Ouch!
In the English (as opposed to American) speaking world this will be very
confusing! The pound sign is £ not #.
If this is not dictated by some sort of upstream PLEASE can we make it
$(hash) not $(pound)

Hi Paul
Below are my preliminary test results tested on PPC VM supplied by
Open source lab of Oregon State University, thank you for your
support!
[Preliminary test results on ppc64le virtual guest]
1. Conclusion
Some other kernel configuration besides RCU may lead to "BUG: Kernel
NULL pointer dereference" at boot
2. Test Environment
2.1 host hardware
8 core ppc64le virtual guest with 16G ram and 160G disk
cpu : POWER9 (architected), altivec supported
clock : 2200.000000MHz
revision : 2.2 (pvr 004e 1202)
2.2 host software
Operating System: Ubuntu 20.04.3 LTS, Compiler: gcc version 9.3.0
3. Test Procedure
3.1 kernel source
next-20220203
3.2 build and boot the kernel with CONFIG_DRM_BOCHS=m and
CONFIG_RCU_TORTURE_TEST=y
test result: "BUG: Kernel NULL pointer dereference" at boot
config file: http://154.223.142.244/Feb2022/config-5.17.0-rc2-next.bochs.torture
boot msg: http://154.223.142.244/Feb2022/dmesg.torture.bochs
3.3 build and boot the kernel with CONFIG_DRM_BOCHS=m
test result: "BUG: Kernel NULL pointer dereference" at boot
config file: http://154.223.142.244/Feb2022/config-5.17.0-rc2-next.bochs
boot msg: http://154.223.142.244/Feb2022/dmesg.bochs
3.4 build and boot the kernel with CONFIG_RCU_TORTURE_TEST=y (without
CONFIG_DRM_BOCHS)
test result: boot without error
config file: http://154.223.142.244/Feb2022/config-5.17.0-rc2-next.torture
boot msg: http://154.223.142.244/Feb2022/dmesg.torture
3.5 build and boot the kernel with CONFIG_RCU_TORTURE_TEST=m (without
CONFIG_DRM_BOCHS)
test result: boot without error
config file: http://154.223.142.244/Feb2022/config-5.17.0-rc2-next
boot msg: http://154.223.142.244/Feb2022/dmesg
4. Acknowledgement
Thank Open source lab of Oregon State University and Paul Menzel and
all other community members who support my tiny research.

openSUSE has the testsuite packaged so it's easy to run on arbitrary
kernel but only on ppc64(le) because there is no ppc there anymore.
So yes, it does not regress Book3S/64 as far as kmod testsuite is
conderned and building s390x non-modular kernel also still worka but
that's not saying much.

I removed all the "`", fixed some unwrapped commit log, shortened some lines
and applied the set to md-next. Please review that version and let me know if
anything need to change.

* [PATCH v2] include: linux: Reorganize timekeeping and ktime headers
From: Carlos Bilbao @ 2022-02-08 16:10 UTC (permalink / raw)
To: john.stultz, tglx, sboyd, alexandre.belloni, gregkh
Cc: linux-rtc, jgross, linux-ia64, kernel test robot, linux-kernel,
rostedt, Carlos Bilbao, linux-m68k, geert, bilbao, boon.leong.ong,
linuxppc-dev, linux-stm32, linux-arm-kernel, mhiramat
The timekeeping subsystem could use some reorganization. Reorganize and
separate the headers by making ktime.h take care of the ktime_get()
family of functions, and reserve timekeeping.h for the actual timekeeping.
This also helps to avoid implicit function errors and strengthens the
header dependencies, since timekeeping.h was using ktime_to_ns(), a static
function defined in a header it does no include, ktime.h.
Include the header timekeeping.h wherever it is necessary for a successful
compilation after the header code reorganization for all archs.

Thanks for your suggestion. I will change the commit message as you
suggested to make it clear. yes, this struct is accessed with mutex.

Which allows the migration code to avoid adding an error path. I could
go either way, but this approach seems fine to me assuming all users of
the global object are guarded by an appropriate lock.

* [PATCH v2 2/2] lib/raid6: Include <asm/ppc-opcode.h> for `VPERMXOR`
From: Paul Menzel @ 2022-02-08 15:21 UTC (permalink / raw)

In-Reply-To: <20220208152148.48534-1-pmenzel@molgen.mpg.de>
On Ubuntu 21.10 (ppc64le) building `raid6test` with gcc (Ubuntu
11.2.0-7ubuntu2) 11.2.0 fails with the error below.
gcc -I.. -I ../../../include -g -O2 -I../../../arch/powerpc/include -DCONFIG_ALTIVEC -c -o vpermxor1.o vpermxor1.c
vpermxor1.c: In function ‘raid6_vpermxor1_gen_syndrome_real’:

| ^~~~~~~~
make: *** [Makefile:58: vpermxor1.o] Error 1
So, include the header `asm/ppc-opcode.h` defining this macro also when
not building the Linux kernel but only this too.

The errors come from the `HAS_ALTIVEC` test, which fails, and the POWER
optimized versions are not built. That’s also reason nobody noticed on the
other architectures.
GNU Make 4.3 does not remove the backslash anymore. From the 4.3 release
announcment:
> * WARNING: Backward-incompatibility!
> Number signs (#) appearing inside a macro reference or function invocation
> no longer introduce comments and should not be escaped with backslashes:
> thus a call such as:
> foo := $(shell echo '#')
> is legal. Previously the number sign needed to be escaped, for example:
> foo := $(shell echo '\#')
> Now this latter will resolve to "\#". If you want to write makefiles
> portable to both versions, assign the number sign to a variable:
> H := \#
> foo := $(shell echo '$H')
> This was claimed to be fixed in 3.81, but wasn't, for some reason.
> To detect this change search for 'nocomment' in the .FEATURES variable.
So, do the same as commit 9564a8cf422d ("Kbuild: fix # escaping in .cmd
files for future Make") and commit 929bef467771 ("bpf: Use $(pound) instead
of \# in Makefiles") and define and use a `$(pound)` variable.
Reference for the change in make:

ppc64_cpu --smt=off sets all but the first CPU per core offline.

That's IRQ_POLL_SOFTIRQ. The problem here is probably that some of these
softirqs are pending even though ksoftirqd has been parked.
I see there is irq_poll_cpu_dead() that migrates the pending queue once
the CPU is finally dead, so this is well handled.
I'm preparing a patch to fix the warning.
Thanks.

The host system runs Linux 5.17-rc1+ started with kexec. Unfortunately,
I am unable to find the exact sha1.

Sorry, that was the wrong path/test. The correct one for the excerpt
below is:

I'm not sure if that's the host kernel version or the version you're
using of rcutorture? Can you tell us the sha1 of your host kernel and of
the tree you're running rcutorture from?

Mine looks pretty much identical:

But mine doesn't segfault, it runs fine and the test completes.
What qemu version are you using?
I tried 4.2.1 and 6.2.0, both worked.

The disassembly from 3c40100f is:
lis r2,4111
addi r2,r2,31744
mr r9,r1
rldicr r1,r1,0,59
li r0,0
stdu r1,-128(r1) <- fault
mtlr r0
std r0,0(r1)
ld r8,-32752(r2)
I think you'll find that's the code at the ELF entry point. You can
check with:
$ readelf -e tools/testing/selftests/rcutorture/initrd/init | grep Entry
Entry point address: 0x10000c0c
$ objdump -d tools/testing/selftests/rcutorture/initrd/init | grep -m 1 -A 8 10000c0c

10000c2c: 10 80 02 e9 ld r8,-32752(r2)
The fault you're seeing is the first store using the stack pointer (r1),
which is setup by the kernel.
The fault address f0656d90 is weirdly low, the stack should be up near 128TB.
I'm not sure how we end up with a bad r1.
Can you dump some info about the kernel that was built, something like:
$ file /dev/shm/linux/tools/testing/selftests/rcutorture/res/2022.02.01-21.52.37-torture/results-rcutorture/TREE03/vmlinux
And maybe paste/attach the full log, maybe there's a clue somewhere.

Dear Linux folks,
On the POWER8 server IBM S822LC running Ubuntu 21.10, Linux 5.17-rc1+
built with
$ grep HZ /boot/config-5.17.0-rc1+
CONFIG_NO_HZ_COMMON=y
# CONFIG_HZ_PERIODIC is not set
CONFIG_NO_HZ_IDLE=y
# CONFIG_NO_HZ_FULL is not set
CONFIG_NO_HZ=y
# CONFIG_HZ_100 is not set
CONFIG_HZ_250=y
# CONFIG_HZ_300 is not set
# CONFIG_HZ_1000 is not set
CONFIG_HZ=250
once warned about a NOHZ tick-stop error, when I executed `sudo
/usr/sbin/ppc64_cpu --smt=off` (so that KVM would work).

PPC folks,
The "%u%u" sscanf() format above seems totally bogus to me. How could 2
unsigned int without a separating characters be parsed as such ? Surely,
a separation character is needed, no ?
I cannot find any documentation on what the intr_coalescing sysfs
attribute format should be... Please have a look.

Use the %u format for unsigned int parameters handling with sscanf() and
sysfs_emit() to avoid compilation warnings. In
fsl_sata_rx_watermark_store(), the call to sscanf() to parse a single
argument is replaced with a call to kstrtouint().
While at it, also replace the printk(KERN_ERR) calls with dev_err()
calls and fix blank lines in fsl_sata_rx_watermark_store().
