[PATCH v5 00/20] x86/kexec: Add exception handling for relocate_kernel and further yak-shaving

[David Woodhouse]

Debugging kexec failures is painful, as anything going wrong in execution
of the critical relocate_kernel() function tends to just lead to a triple
fault. Thus leading to *weeks* of my life that I won't get back. Having
hacked something up for my own use, I figured I should share it...

Add a CONFIG_KEXEC_DEBUG option which sets up a trivial exception 
handler in that environment, and outputs to the early_printk serial 
console if configured. Currently only 8250-compatible serial ports are 
supported, but that could be extended.

While we're here, clean the code up a little and fix some other problems. 
Most notably, load a suitable GDT on the way back into the kernel after a 
KEXEC_PRESERVE_CONTEXT invocation instead of trusting the called code to do 
so.

I had to hack up QEMU support for a PCI serial port which matches what
the existing early_printk code can drive, and the *real* 8250_pci driver
doesn't seem to cope with that setup at all, but whatever... the kexec
code now drives the same 32-bit stride which is all that earlyprintk
supports. We can always add more later, if anyone cares.

Someone who cares might want to bring the i386 version into line with 
this, although the lack of rip-based addressing makes all the PIC code a 
bit harder.

v5:
 • Drop [RFC].
 • Drop _PAGE_NOPTISHADOW fix, which Ingo already took into tip/x86/urgent.
 • Add memory-mapped serial port support (32-bit MMIO spacing only).

v4 (RFC): https://lore.kernel.org/kexec/20241127190343.44916-1-dwmw2@infradead.org/T/
 • Add _PAGE_NOPTISHADOW fix for the identmap code.
 • Drop explicit map of control page, which was masking the identmap bug.

v3 (RFC): https://lore.kernel.org/kexec/20241125100815.2512-1-dwmw2@infradead.org/T/
 • Add CONFIG_KEXEC_DEBUG option and use earlyprintk config.
 • Allocate PGD separately from control page.
 • Explicitly map control page into identmap.

V2 (RFC): https://lore.kernel.org/kexec/20241122224715.171751-1-dwmw2@infradead.org/T/
 • Introduce linker script, start to clean up data access.

V1 (RFC): https://lore.kernel.org/kexec/20241103054019.3795299-1-dwmw2@infradead.org/T/
 • Initial proof-of-concept hacks.

[PATCH v5 01/20] x86/kexec: Restore GDT on return from preserve_context kexec

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

The restore_processor_state() function explicitly states that "the asm code
that gets us here will have restored a usable GDT". That wasn't true in the
case of returning from a preserve_context kexec. Make it so.

Without this, the kernel was depending on the called function to reload a
GDT which is appropriate for the kernel before returning.

Test program:

 #include <unistd.h>
 #include <errno.h>
 #include <stdio.h>
 #include <stdlib.h>
 #include <linux/kexec.h>
 #include <linux/reboot.h>
 #include <sys/reboot.h>
 #include <sys/syscall.h>

int main (void)
{
        struct kexec_segment segment = {};
	unsigned char purgatory[] = {
		0x66, 0xba, 0xf8, 0x03,	// mov $0x3f8, %dx
		0xb0, 0x42,		// mov $0x42, %al
		0xee,			// outb %al, (%dx)
		0xc3,			// ret
	};
	int ret;

	segment.buf = &purgatory;
	segment.bufsz = sizeof(purgatory);
	segment.mem = (void *)0x400000;
	segment.memsz = 0x1000;
	ret = syscall(__NR_kexec_load, 0x400000, 1, &segment, KEXEC_PRESERVE_CONTEXT);
	if (ret) {
		perror("kexec_load");
		exit(1);
	}

	ret = syscall(__NR_reboot, LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2, LINUX_REBOOT_CMD_KEXEC);
	if (ret) {
		perror("kexec reboot");
		exit(1);
	}
	printf("Success\n");
	return 0;
}

[PATCH v5 05/20] x86/kexec: Allocate PGD for x86_64 transition page tables separately

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

Now that commit d0ceea662d45 ("x86/mm: Add _PAGE_NOPTISHADOW bit to
avoid updating userspace page tables") stops kernel_ident_mapping_init()
from scribbling over the end of a 4KiB PGD by assuming the following
4KiB will be a userspace PGD, there's no good reason for the kexec PGD
to be part of a single 8KiB allocation with the control_code_page.

(It's not clear that that was the reason for x86_64 kexec doing it that
way in the first place either; there were no comments to that effect and
it seems to have been the case even before PTI came along. It looks like
it was just a happy accident which prevented memory corruption on kexec.)

Either way, it definitely isn't needed now. Just allocate the PGD
separately on x86_64, like i386 already does.

future changes will need to make the control page read-only and executable,
so all writes should be completed before machine_kexec_prepare() returns.

[PATCH v5 07/20] x86/kexec: Invoke copy of relocate_kernel() instead of the original

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

This currently calls set_memory_x() from machine_kexec_prepare() just
like the 32-bit version does. That's actually a bit earlier than I'd
like, as it leaves the page RWX all the time the image is even *loaded*.

Subsequent commits will eliminate all the writes to the page between the
point it's marked executable in machine_kexec_prepare() the time that
relocate_kernel() is running and has switched to the identmap %cr3, so
that it can be ROX. But that can't happen until it's moved to the .data
section of the kernel, and *that* can't happen until we start executing
the copy instead of executing it in place in the kernel .text. So break
the circular dependency in those commits by letting it be RWX for now.

[PATCH v5 08/20] x86/kexec: Move relocate_kernel to kernel .data section

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

Now that the copy is executed instead of the original, the relocate_kernel
page can live in the kernel's .text section. This will allow subsequent
commits to actually add real data to it and clean up the code somewhat as
well as making the control page ROX.

Now that the relocate_kernel page is handled sanely by a linker script
we can have actual data, and just use %rip-relative addressing to access
it.

[PATCH v5 10/20] x86/kexec: Drop page_list argument from relocate_kernel()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

The kernel's virtual mapping of the relocate_kernel page currently needs
to be RWX because it is written to before the %cr3 switch.

Now that the relocate_kernel page has its own .data section and local
variables, it can also have *global* variables. So eliminate the separate
page_list argument, and write the same information directly to variables
in the relocate_kernel page instead. This way, the relocate_kernel code
itself doesn't need to copy it.

[PATCH v5 11/20] x86/kexec: Eliminate writes through kernel mapping of relocate_kernel page

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

All writes to the relocate_kernel control page are now done *after* the
%cr3 switch via simple %rip-relative addressing, which means the DATA()
macro with its pointer arithmetic can also now be removed.

[PATCH v5 12/20] x86/kexec: Clean up register usage in relocate_kernel()

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

The memory encryption flag is passed in %r8 because that's where the
calling convention puts it. Instead of moving it to %r12 and then using
%r8 for other things, just leave it in %r8 and use other registers
instead.

All writes to the page now happen before it gets marked as executable

OK to be RWX).

[PATCH v5 15/20] x86/kexec: Debugging support: load a GDT

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

There are some failure modes which lead to triple-faults in the
relocate_kernel function, which is fairly much undebuggable for normal
mortals.

Adding a GDT in the relocate_kernel environment is step 1 towards being
able to catch faults and do something more useful.

[PATCH v5 19/20] x86/kexec: Add 8250 MMIO serial port output

[David Woodhouse]

From: David Woodhouse <dwmw@amazon.co.uk>

This supports the same 32-bit MMIO-mapped 8250 as the early_printk code.

It's not clear why the early_printk code supports this form and only this
form; the actual runtime 8250_pci doesn't seem to support it. But having
hacked up QEMU to expose such a device, early_printk does work with it,
and now so does the kexec debug code.

x86/kexec: Restore GDT on return from ::preserve_context kexec

The restore_processor_state() function explicitly states that "the asm code
that gets us here will have restored a usable GDT". That wasn't true in the
case of returning from a ::preserve_context kexec. Make it so.

Without this, the kernel was depending on the called function to reload a
GDT which is appropriate for the kernel before returning.

Test program:

 #include <unistd.h>
 #include <errno.h>
 #include <stdio.h>
 #include <stdlib.h>
 #include <linux/kexec.h>
 #include <linux/reboot.h>
 #include <sys/reboot.h>
 #include <sys/syscall.h>

 int main (void)
 {
        struct kexec_segment segment = {};
	unsigned char purgatory[] = {
		0x66, 0xba, 0xf8, 0x03,	// mov $0x3f8, %dx
		0xb0, 0x42,		// mov $0x42, %al
		0xee,			// outb %al, (%dx)
		0xc3,			// ret
	};
	int ret;

	segment.buf = &purgatory;
	segment.bufsz = sizeof(purgatory);
	segment.mem = (void *)0x400000;
	segment.memsz = 0x1000;
	ret = syscall(__NR_kexec_load, 0x400000, 1, &segment, KEXEC_PRESERVE_CONTEXT);
	if (ret) {
		perror("kexec_load");
		exit(1);
	}

	ret = syscall(__NR_reboot, LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2, LINUX_REBOOT_CMD_KEXEC);
	if (ret) {
		perror("kexec reboot");
		exit(1);
	}
	printf("Success\n");
	return 0;
 }

x86/kexec: Mark relocate_kernel page as ROX instead of RWX

All writes to the page now happen before it gets marked as executable
(or after it's already switched to the identmap page tables where it's
OK to be RWX).

x86/kexec: Clean up register usage in relocate_kernel()

The memory encryption flag is passed in %r8 because that's where the
calling convention puts it. Instead of moving it to %r12 and then using
%r8 for other things, just leave it in %r8 and use other registers
instead.

x86/kexec: Eliminate writes through kernel mapping of relocate_kernel page

All writes to the relocate_kernel control page are now done *after* the
%cr3 switch via simple %rip-relative addressing, which means the DATA()
macro with its pointer arithmetic can also now be removed.

x86/kexec: Drop page_list argument from relocate_kernel()

The kernel's virtual mapping of the relocate_kernel page currently needs
to be RWX because it is written to before the %cr3 switch.

Now that the relocate_kernel page has its own .data section and local
variables, it can also have *global* variables. So eliminate the separate
page_list argument, and write the same information directly to variables
in the relocate_kernel page instead. This way, the relocate_kernel code
itself doesn't need to copy it.

x86/kexec: Add data section to relocate_kernel

Now that the relocate_kernel page is handled sanely by a linker script
we can have actual data, and just use %rip-relative addressing to access
it.

x86/kexec: Move relocate_kernel to kernel .data section

Now that the copy is executed instead of the original, the relocate_kernel
page can live in the kernel's .text section. This will allow subsequent
commits to actually add real data to it and clean up the code somewhat as
well as making the control page ROX.

x86/kexec: Invoke copy of relocate_kernel() instead of the original

This currently calls set_memory_x() from machine_kexec_prepare() just
like the 32-bit version does. That's actually a bit earlier than I'd
like, as it leaves the page RWX all the time the image is even *loaded*.

Subsequent commits will eliminate all the writes to the page between the
point it's marked executable in machine_kexec_prepare() the time that
relocate_kernel() is running and has switched to the identmap %cr3, so
that it can be ROX. But that can't happen until it's moved to the .data
section of the kernel, and *that* can't happen until we start executing
the copy instead of executing it in place in the kernel .text. So break
the circular dependency in those commits by letting it be RWX for now.

x86/kexec: Copy control page into place in machine_kexec_prepare()

There's no need for this to wait until the actual machine_kexec() invocation;
future changes will need to make the control page read-only and executable,
so all writes should be completed before machine_kexec_prepare() returns.

x86/kexec: Allocate PGD for x86_64 transition page tables separately

Now that the following fix:

  d0ceea662d45 ("x86/mm: Add _PAGE_NOPTISHADOW bit to avoid updating userspace page tables")

stops kernel_ident_mapping_init() from scribbling over the end of a
4KiB PGD by assuming the following 4KiB will be a userspace PGD,
there's no good reason for the kexec PGD to be part of a single
8KiB allocation with the control_code_page.

( It's not clear that that was the reason for x86_64 kexec doing it that
  way in the first place either; there were no comments to that effect and
  it seems to have been the case even before PTI came along. It looks like
  it was just a happy accident which prevented memory corruption on kexec. )

Either way, it definitely isn't needed now. Just allocate the PGD
separately on x86_64, like i386 already does.

x86/kexec: Only swap pages for ::preserve_context mode

There's no need to swap pages (which involves three memcopies for each
page) in the plain kexec case. Just do a single copy from source to
destination page.

x86/kexec: Clean up and document register use in relocate_kernel_64.S

Add more comments explaining what each register contains, and save the
preserve_context flag to a non-clobbered register sooner, to keep things
simpler.

No change in behavior intended.

I just bisected a change in behavior that I see in to this change in
-next as commit 5a82223e0743 ("x86/kexec: Mark relocate_kernel page as
ROX instead of RWX"). I usually kexec my machines by running:

  # kexec --load /boot/vmlinuz-linux --initrd /boot/initramfs-linux.img --reuse-cmdline

  # systemctl kexec

to cleanly shutdown userspace then kexec into the new kernel after
installing it via the package manager. After this change, I get sent to
systemd-boot after running 'systemctl kexec', which selects the default
entry, my distribution kernel.

I just see:

  [  OK  ] Reached target Reboot via kexec.
  BdsDxe: loading Boot0007 "Linux Boot Manager" from HD(1,GPT,4B5AFD80-5EC7-47FC-83EA-7EC88ACB15A7,0x800,0x200000)/\EFI\systemd\systemd-bootx64.efi

then the systemd-boot menu in QEMU when reproducing this there.

Is this expected? If not, I am happy to provide any information or test
patches as necessary.

Cheers,
Nathan

Hi David,

I've hit some kdump/kexec regression issue for guest kernel in KVM/QEMU 
based VM and reported in https://bugzilla.kernel.org/show_bug.cgi?id=219592.

based on further git bisect, it seems to be related with this commit, 
would you help to take a look?

Thanks for the report; I'll take a look. Please could you share your
kernel .config?

Also, you say that this is in QEMU running on an IA64 host. Is that
true, or did you mean x86_64 host? Are you using OVMF or SeaBIOS as the
QEMU firmware?

In the short term, I think that just reverting the 'offending' commit
should be OK. I'd *prefer* not to leave the page RWX for the whole time
period that the image is loaded, but that's how it's been on i386 for
ever anyway.

No, definitely not expected. Thanks for the report. I'll see if I can
reproduce it; please could you share your kernel .config?

Please could you also confirm that it still occurs if you don't use
systemctl; for speed of testing I have mostly been booting my test
kernel with no actual root file system; just an initrd which does
'kexec -f' immediately.

Since you are running in QEMU, if you can reproduce with this patch to
QEMU itself which should dump the CPU state on a triple-fault, it would
be very useful please:

Yes, it appears to reproduce with just 'kexec -e' after 'kexec -l'.

Here is the output that I see with that patch applied when rebooting via
'systemctl kexec':

So it's faulting when it tries to write to saved_rsp, which is the
first instruction after it loads the new page tables into %cr3.

Before loading %cr3, the CPU is running on the original kernel page
tables, It's running from the *virtual* address of the control page,
which in your case is ff1cd0425c444000. In those old page tables, this
control page is read-only.

But in the newly-loaded page tables, this control page should be read-
write. 

What CPU is this? Shouldn't loading %cr3 have caused the existing TLB
entry to be flushed?

Can you tell me what happens if we don't write through *that* virtual
mapping of the page, but instead do it a few instructions later through
the identity mapping of the same page (which surely *won't* have an
older, non-writeable TLB entry already...)?

The machine I have mainly been reproducing and testing this issue on is
an Intel Xeon Gold 6314U but I initially noticed this problem on a few
consumer AMD and Intel chips that I have locally.

Applying that diff on top of 5a82223e0743 makes the issue go away for
me.

Not on my Haswell Xeon box though, it seems.

Dave Hansen points out that it's probably the _PAGE_GLOBAL bit; that
TLB entry *won't* get flushed.

Thanks. It actually seems to break the preserve_context mode for me, so
I'll give it a bit more thought and probably come back to you with
another version to test.

[PATCH] x86/kexec: Only write through identity mapping of control page

[David Woodhouse]

[-- Attachment #1: Type: text/plain, Size: 3032 bytes --]

From: David Woodhouse <dwmw@amazon.co.uk>

The virtual mapping of the control page may have been _PAGE_GLOBAL and
thus its PTE might not have been flushed on the %cr3 switch and it might
effectively still be read-only. Move the writes to it down into the
identity_mapped() function where the same %rip-relative addressing will
get the new mapping.

The stack is fine, as that's using the identity mapped address anyway.

Shouldn't we also ensure that Global entries don't bite anyone else?

Doesn't hurt, but this is an identity mapping so absolutely everything other than this one page is going to be in the low (positive) part of the canonical address space, so won't have had global pages in the first place will they?

Probably a kind thing to do for whatever we're passing control to though :)

I'll round it up into the tree and send it out with the next batch of debug support. Care to give me a SoB for it? You can s/CR0_PGE/CR4_PGE/ too if you like but I can do that myself as well.

Right, it's generally _not_ a problem. But it _can_ be a surprising
problem which is why we're all looking at it today. ;)

Here's a fixed one with a changelog and a SoB. Still 100% gloriously
untested though.

Subject: [PATCH] x86/mm: Ensure Global mappings are zapped during kexec

The kernel switches to a new set of page tables during kexec. The
global mappings (_PAGE_GLOBAL==1) can remain in the TLB after this
switch. This is generally not a problem because the new page tables
use a different portion of the virtual address space than the normal
kernel mappings.

But there's no good reason to leave the old TLB entries around. They
can cause nothing but trouble. Clear "Page Global Enable"
(X86_CR4_PGE). This, along with the CR3 write ensures that there is
no trace of the old page tables in the TLB, even global entries.

Ta. I'll play with it in the morning. May actually shift it earlier and use it instead of my other fix, so we can actually write to the virtual address.

[PATCH] x86/kexec: Disable global pages before writing to control page

[David Woodhouse]

[-- Attachment #1: Type: text/plain, Size: 2798 bytes --]

From: David Woodhouse <dwmw@amazon.co.uk>

The kernel switches to a new set of page tables during kexec. The global
mappings (_PAGE_GLOBAL==1) can remain in the TLB after this switch. This
is generally not a problem because the new page tables use a different
portion of the virtual address space than the normal kernel mappings.

The critical exception to that generalisation (and the only mapping
which isn't an identity mapping) is the kexec control page itself —
which was ROX in the original kernel mapping, but should be RWX in the
new page tables. If there is a global TLB entry for that in its prior
read-only state, it definitely needs to be flushed before attempting to
write through that virtual mapping.

It would be possible to just avoid writing to the virtual address of the
page and defer all writes until they can be done through the identity
mapping. But there's no good reason to keep the old TLB entries around,
as they can cause nothing but trouble.

Clear the PGE bit in %cr4 early, before storing data in the control page.

figured out what's going on.

You're right, it's x86_64 host, I miss-selected it in bugzilla.
I'm using OVMF as the QEMU firmware.

I guess this seems somewhat unavoidable because control_page is just a
'void *', perhaps machine_kexec() should just be marked as __nocfi? This
diff resolves that issue for me.

Thanks. Could I have that with a SoB please? I can craft a commit message if you need. I'll round it up with a couple of other fixups I already have in my tree, and send them on.

The patch below seems to work too. I already wanted to deal with the
case where relocate_kernel isn't at the start of the page, so it forces
me to do that.

For some reason it also started complaining
vmlinux.o: warning: objtool: relocate_kernel+0x6a: return with modified stack frame
... which is easy to fix just by turning it into a jmp *%rsi; I have no
idea why it was done with a ret like that in the first place.

I don't know why it puts 16 bytes of NOPs between __reloc_start and
__cfi_relocate_kernel (in addition to the 16 before relocate_kernel
itself), and space is *fairly* tight in the control page, but it's
tolerable.

To make the CFI check actually give useful output if it triggers, I'm
tempted to do the IDT/GDT invalidation relocate_kernel itself, instead
of before the call.

Can confirm, thanks for the quick fix. With your fix for the first issue
I reported, the fix I sent for LTO, and this patch below, I can kexec on
a CFI and LTO enabled kernel without any issues.

I think this is something to do with FineIBT IIRC? PeterZ might have
more details.

Thank you for testing.  Which is the LTO one? Is it in my tree yet or
have I missed it?

(The fix we're discussing here isn't there yet; it still needs
polishing)

Argh, using SYM_TYPED_FUNC_START() leads to objtool having more opinions.

I have the Clang build working in my tree now, but the GCC build now complains

vmlinux.o: warning: objtool: relocate_kernel+0x0: unreachable instruction

It seems like adding UNWIND_HINT_FUNC ought to be the answer for that?
But then it complains about this instead:

vmlinux.o: warning: objtool: relocate_kernel+0x69: unsupported stack register modification

That's the lea instruction at
       lea     PAGE_SIZE(%rsi), %rsp
 79:   48 8d a6 00 10 00 00    lea    0x1000(%rsi),%rsp

I've pushed what I have to my kexec-debug branch; I was hoping to post
the fixes for the tip/x86/boot branch this morning but I've run out of
time and will be travelling for the rest of the week. Will try to get
something sent out this evening when I land.

I may resort to the __nocfi option for now. As noted on the typedef
patch and in IRC, the whole SYM_TYPED_FUNC_START() thing using the type
information from the *C* code which is actually doing the call anyway,
is a bit tautological anyway.

I've dropped this for now and just posted the __nocfi thing as the
regression fix. I think we *should* provide the CFI information in
relocate_kernel_64.S though, so I've left these commits in my tree at
https://git.infradead.org/?p=users/dwmw2/linux.git;a=shortlog;h=refs/heads/kexec-debug

I'd really appreciate some help in getting objtool to stop whining
about them, for *both* Clang and GCC builds at the same time :)

Hm, I can't fetch for some reason:

  $ git fetch https://git.infradead.org/users/dwmw2/linux.git kexec-debug
  fatal: https://git.infradead.org/users/dwmw2/linux.git/info/refs not valid: could not determine hash algorithm; is this a git repository?

At some point we had discussed placing the code in .rodata, was it the
alternative preventing that?

The https URL is just gitweb. You can fetch from 
git://git.infradead.org/users/dwmw2/linux.git

No, the alternative seems to be fine, and it's all in the .data section
now (since the kernel does write some variables there which are then
accessed %rip-relative from the code itself).

The problem is when I use SYM_TYPED_FUNC_START for relocate_kernel
itself, objtool starts to whine that the first instruction of
relocate_kernel is unreachable (presumably) because it is never jumped
to directly, but copied into the control page and then called via a
calculated function pointer).

There's also an objtool warning about loading the stack pointer. I seem
to get different warnings from objtool for Clang and GCC builds, and
can't find a set of hints which will make them both shut up at the same
time.

The linker script does place it in .data, but objtool runs on the object
file before linking, where it's still in an executable section
(.text..relocate_kernel).

How about something like below?

  - move text to .data..relocate_kernel
  - remove objtool annotations
  - replace the alternative with a runtime check

That leaves me unable to use 'objdump -S
arch/x86/kernel/relocate_kernel_64.o' so I hate it :)

At the moment objtool is *mostly* happy with the code in here; is there
no way to make it happy even with the CFI annotation?

In practice I probably don't even need to use SYM_TYPED_FUNC_START()
anyway, as it's doing the wrong thing. It's pointless if it just uses
the external __cfi_typeid_relocate_kernel symbol that the C code emits,
because that's obviously going to match the prototype that the C code
expects.

So I might emit the __cfi_relocate_kernel prologue entirely manually,
and then maybe objtool will thinking it's entitled to opinions :)

Well, it's already written in assembly, there's not much benefit in
disassembling it ;-)  But you can still force gdb to do so with
something like "x/50i <addr>".

Isn't that easier than putting in all these hacks to make objtool happy
(and continue to keep it happy over the coming years), when it doesn't
need to care about this code in the first place?

Anyway, what I think you're looking for is UNWIND_HINT_UNDEFINED.  In
fact all the unwind annotations in that file should be UNDEFINED since
the hints are all referring to the wrong addresses (because copied code)
and the ORC unwinder isn't reachable for most of that code anyway.

Also, it's fine to make relocate_kernel() a proper function with
SYM_FUNC_END, you'd just need to add the following line afterwards:

  STACK_FRAME_NON_STANDARD relocate_kernel

I've spent a lot of time recently wanting to know precisely which
instruction it was that faulted (or that objtool is complaining about),
so I *have* wanted to disassemble it. But yeah, in the general case
that shouldn't be something we're doing all the time.

Perhaps you're right, and we should just rip out all the annotations
and move it to .data..relocate_kernel. But I'll give it a bit more
effort to see if we can make objtool happy and keep the ALTERNATIVE
working without having to do that manually...

Less worried about the 'continue' part. This code doesn't get much
churn (not until I just came along and blitzed it, at least).

Thanks, I'll take a look. The next thing objtool is actually
complaining about is that relocate_kernel() itself is not reachable
(since it's never invoked in its original location):

vmlinux.o: warning: objtool: relocate_kernel+0x0: unreachable instruction

I'm not sure why objtool has only just started whining about that with
the very last patches at the top of my tree; it's been true ever since
the commit which executes from the relocated copy.

Right, I think UNWIND_HINT_UNDEFINED should fix that.
