Commit 109303336a0c ("crypto: vmx - Move to arch/powerpc/crypto") moves the
crypto vmx files to arch/powerpc, but misses to adjust the file entries for
IBM Power VMX Cryptographic instructions and LINUX FOR POWERPC.

The generic vtime_task_switch() implementation gets built only
if __ARCH_HAS_VTIME_TASK_SWITCH is not defined, but requires an
architecture to implement arch_vtime_task_switch() callback at
the same time, which is confusing.
Further, arch_vtime_task_switch() is implemented for 32-bit PowerPC

update_timer_sys() and update_timer_mcck() are inlines used for
CPU time accounting from the interrupt and machine-check handlers.
These routines are specific to s390 architecture, but included
via header implicitly. Avoid the extra loop and

Hi All,
I kept all tags on reveiwed patches.
v2:
- patch 4: commit message reworded (Heiko)
- patch 5: vtime.h is removed from Kbuild scripts (PowerPC only) (Heiko)
v1:
Please find a small cleanup to vtime_task_switch() wiring.
I split it into smaller patches to allow separate PowerPC
vs s390
__ARCH_HAS_VTIME_TASK_SWITCH macro is not used anymore.

There is no architecture-specific code or data left

reg.h is updated with Power11 pvr. pvr_mask value of 0x0F07
means we are arch v3.1 compliant. This is used by phyp and
kvm when booting as a pseries guest to detect and enable
the appropriate hwcap, facility bits and PMU related fields.
Copied most of fields from Power10 table entry.

Since v2:
- Rebase on riscv port and auxvinfo fix was merged.
- Clean up initrd cleanup moves more commands into the new cleanup
function from the trap handler comands (suggested by Thomas).
- "arch-run: Clean up temporary files properly" patch is now renamed
to "arch-run: Fix TRAP handler..."
Migration files were not being removed when the QEMU process is
interrupted (e.g., with ^C). This is becaus the SIGINT propagates to the
bash TRAP handler, which recursively TRAPs due to the 'kill 0' in the
handler. This eventually crashes bash.
This can be observed by interrupting a long-running

Test cases may now switch to calling migrate() one or more times.
