linux-next: rr tree build failure

[Stephen Rothwell]

Hi Rusty,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

arch/powerpc/kernel/irq.c: In function 'fixup_irqs':
arch/powerpc/kernel/irq.c:240: error: incompatible type for argument 2 of 'irq_desc[irq].chip->set_affinity'

arch/powerpc/platforms/pseries/xics.c:864: error: incompatible type for argument 2 of 'desc->chip->set_affinity'

caused by commit 5b03e170d524383a34a89fd73ec9d1bda0922d63
("cpumask:irq-functions-take-cpumask_t-ptr") which changed the
set_affinity callback but didn't update all the instances.

I have dropped the rr tree again today.

Not sure how these got through.  I did another sweep.

linux-next: rr tree build failure

Hi Rusty,

The cpufreq patch above is now in Linus' tree, so You should add the
patch below to your tree (or squash it into the affected patch).

linux-next: rr tree build failure

[Stephen Rothwell]

Hi Rusty,

Today's linux-next build (powerpc ppc44x_defconfig) failed like this:

.tmp_exports-asm.o: In function `__ksymtab_pci_alloc_consistent':
(__ksymtab_sorted+0x2a30): undefined reference to `pci_alloc_consistent'
.tmp_exports-asm.o: In function `__ksymtab_pci_free_consistent':
(__ksymtab_sorted+0x2b70): undefined reference to `pci_free_consistent'

Caused by the powerpc architecture EXPORTing static inlines (for 32 bit
builds) interacting with changes in the rr tree.

I have applied this patch for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Thu, 12 Nov 2009 18:54:13 +1100
Subject: [PATCH] powerpc: do not export pci_alloc/free_consistent

Since they are static inline functions.

Thanks. Our EXPORTs are bogus (probably leftovers) it seems. I'll dbl
check tomorrow but that looks like a patch I should pickup in powerpc
-next anyways.

It's inline and exported when CONFIG_PARAVIRT=y.  Which is wrong.

Here's the patch I've put in my series for tomorrow's linux-next:

Subject: x86: don't export inline function

For CONFIG_PARAVIRT, load_gs_index is an inline function (it's #defined
to native_load_gs_index otherwise).

Exporting an inline function breaks the new assembler-based alphabetical
sorted symbol list:

Looks like I have made some bad assumptions. I will re-write the
original patch to be x86-only.

Sorry for breaking the build.

I have posted a replacement patch for that commit: "[PATCH v6] RO/NX
protection for loadable kernel modules"
Please let me know if you would rather see a short "patch patch"
rather than complete patch replacement. The fix, essentially, is to
encapsulate entire bodies of unset_section_ro_nx() and
set_section_ro_nx() inside #ifdef CONFIG_X86 ... #endif. This way
set_memory_* will be called only on x86.

Thanks.

Sorry, was on leave for 3 weeks.  I hope Linus will be flexible; many of these
patches have been in linux-next for months now, it'd be nice to unload.

Looks like I'm doing this the wrong way (by passing a cpumask on the
stack).  I'll try to figure out the approved way of doing this and
send a followup patch.

Here's a patch to fix this.  Since Linus' tree still contains instances
of set_cpus_allowed(), I'm guessing this patch should be added to the rr
tree?

Bjorn



ACPI: remove cpumask_t usage

set_cpus_allowed() is on the way out; replace it with
set_cpus_allowed_ptr().

Since set_cpus_allowed_ptr() aleeady exists in Linus' tree, you could put
that patch in your tree, Bjorn.

> Yep, my series removes it, at least for CONFIG_CPUMASK_OFFSTACK=y.

So one of you (at least) should apply that patch to your tree!  Please?

Hi Rusty,

Today's linux-next build (sparc64 defconfig) failed like this:

arch/sparc/mm/init_64.c: In function 'paging_init':
arch/sparc/mm/init_64.c:1802: error: 'CPU_MASK_ALL_PTR' undeclared (first use in this function)

Caused by commit 3360ebad15b16eac7b0205595d6fe561716725c5
("cpumask:remove-CPU_MASK_ALL_PTR") from the rr tree interacting with
commits 21bc149d59288fe43d1ba18a59d874ba6a5f1db9 ("sparc64: Make

Rusty, I assume that there is something that Dave can use in the sparc
tree already instead of CPU_MASK_ALL_PTR (cpu_all_mask?).

I have reverted the rr tree patch for today - after reverting these other
patches as well:

linux-next: rr tree build failure

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 702 bytes --]

Hi Rusty,

Today's linux-next build (sparc64 defconfig) failed like this:

drivers/pci/probe.c: In function 'pci_bus_show_cpuaffinity':
drivers/pci/probe.c:56: error: 'CPU_MASK_ALL_PTR' undeclared (first use in this function)

Caused by commit 66ec53ceff39a3daf3b1a3628bca1198bd88c7b3
("cpumask:remove-CPU_MASK_ALL_PTR"). 2.6.29-rc2 added cpumask_of_pcibus()
(which references CPU_MASK_ALL_PTR) to
arch/sparc/include/asm/topology_64.h .

I have reverted that commit (as well as commit
ba5eb00621351d4f16270cf2db0932fe2c7067f3 ("cpumask:remove-cpu_mask_all")
that depended on it).

Hmm, I *did* get that, but somehow lost it from the series file in the patch
shuffle.

cpumask:remove-address-of-CPU_MASK_ALL-sparc.patch

cpumask: remove dangerous CPU_MASK_ALL_PTR, &CPU_MASK_ALL.: sparc

Impact: cleanup

(Thanks to Al Viro for reminding me of this, via Ingo)

CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so:

	#define CPU_MASK_ALL (cpumask_t) { { ... } }

Taking the address of such a temporary is questionable at best,
unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added
CPU_MASK_ALL_PTR:

	#define CPU_MASK_ALL_PTR (&CPU_MASK_ALL)

Which formalizes this practice.  One day gcc could bite us over this
usage (though we seem to have gotten away with it so far).

So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR
with the modern "cpu_all_mask" (a real struct cpumask *), and remove
CPU_MASK_ALL_PTR altogether.

Also remove the confusing and deprecated large-NR_CPUS-only
"cpu_mask_all".

Hi Stephen,

I have this fixed in:


commit 3b656ce6c3d7ea2a36c1ebe77d436d5550980baa
Author: Mike Travis <travis@sgi.com>
Date:   Sat Dec 27 01:45:56 2008 -0800

    x86: cleanup remaining cpumask_t ops in smpboot code

which was pushed via tip/cpus4096.  It includes many other
updates so I'm not exactly sure how this merges into
linux-next.

Thanks,
Mike

Oh, fun.  We added a config option to disable the deprecated cpus_* functions;
it's mainly for those interested in helping with the conversion.

Of course, allmodconfig turns it on.  I made it depend on CONFIG_BROKEN for now.

Thanks,
Rusty.

Hi Rusty,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

arch/powerpc/sysdev/mpic.c:809: error: conflicting types for 'mpic_set_affinity'
arch/powerpc/sysdev/mpic.h:39: error: previous declaration of 'mpic_set_affinity' was here

The declaration in the header file was missed.

Also, the x86_64 allmodconfig build failed like this:

ERROR: "hvc_resize" [drivers/char/virtio_console.ko] undefined!

hvc_resize is currently not exported to modules.

I have dropped the rr tree again.

Thanks, fixed.  Grepping found some more sparc ones, too.

OK, I've dropped Christian's patch for the moment until he fixes this.  I'm 
travelling to Sydney for the day so I won't get a chance to fix this if it 
breaks tomorrow :(

Ok. Sorry about that. allmodconfig on s390 and i386 select VIRTIO_CONSOLE as 
(y) and not as (m), therefore my tests did not trigger this problem. I will 
try to get an x86_64 box to test on in the future.

This version of the patch adds an EXPORT_SYMBOL_GPL. Feel free to add it 
whenever it fits your schedule. 

[PATCH 1/2]: virtio_console: support console resizing

From: Christian Borntraeger <borntraeger@de.ibm.com>

this patch uses the new hvc callback hvc_resize to set the window site 
which allows to change the tty size of hvc_console via a hvc_resize 
function.

I have added a new feature bit VIRTIO_CONSOLE_F_SIZE. The driver will 
change the window size on tty open and via the config_changed callback
of the transport. Currently lguest and kvm_s390 have not implemented this
callback, but the callback can be implemented at a later point in time.

Thanks, applied.

For future reference I've taken to preferring fixup patches, which I can fold

Yes, I didn't get a reply from Greg about whether he really needs "nousb" to
be a module param, so I dropped my proposed USB fix.  I've restored it now.

Greg, here's the complete patch I have now:

Subject: USB: Use core_param.

Found this when I changed args to __module_param_call.  We now have
core_param for exactly this.

This reverts to the 2005 (pre- aafbf24a) behaviour where "nousb" was
not a module parameter, just a kernel command line parameter.  That's
more sensible anyway.

OK, after discussions with Arnd I applied two fixes.  One is similar to yours 
but neater, and the other then changes NR_CPUS to nr_cpu_ids once it becomes 
available for UP.

Hmm, prefer either tristate "Virtio console" or "depends on VIRTIO = y". 
select has issues in that it ignores dependencies.
