Hi Linus,

Please pull powerpc updates for 5.11.

There's only one conflict I'm aware of, which is the three lkdtm files,
resolution is simply to take both sides.

Notable out of area changes:
drivers/misc/lkdtm/* # 3ba150fb2120 lkdtm/powerpc: Add SLB multihit test
tools/testing/selftests/lkdtm/tests.txt

include/linux/compat.h # 14026b94ccfe signal: Add unsafe_put_compat_sigset()
include/linux/memory_hotplug.h # 4abb1e5b63ac powerpc/mm: factor out creating/removing linear mapping
include/linux/regset.h # 640586f8af35 powerpc/ptrace: Simplify gpr_get()/tm_cgpr_get()

cheers

powerpc/32s: Fix cleanup_cpu_mmu_context() compile bug (2020-12-17 14:33:35 +1100)

- ------------------------------------------------------------------
powerpc updates for 5.11

- Switch to the generic C VDSO, as well as some cleanups of our VDSO
setup/handling code.

- Support for KUAP (Kernel User Access Prevention) on systems using the hashed
page table MMU, using memory protection keys.

- Better handling of PowerVM SMT8 systems where all threads of a core do not
share an L2, allowing the scheduler to make better scheduling decisions.

- Further improvements to our machine check handling.

- Show registers when unwinding interrupt frames during stack traces.

- Improvements to our pseries (PowerVM) partition migration code.

- Several series from Christophe refactoring and cleaning up various parts of
the 32-bit code.

- Other smaller features, fixes & cleanups.
