Pull powerpc updates from Michael Ellerman:
- Extend KCSAN support to 32-bit and BookE. Add some KCSAN annotations
- Make ELFv2 ABI the default for 64-bit big-endian kernel builds, and
use the -mprofile-kernel option (kernel specific ftrace ABI) for big
endian ELFv2 kernels
- Add initial Dynamic Execution Control Register (DEXCR) support, and
allow the ROP protection instructions to be used on Power 10
- Various other small features and fixes

__strncpy_user is only used when CONFIG_ARCH_HAS_STRNCPY_FROM_USER is
enabled so don't build the source when it's off.

The stubs were provided by commit 725aea873261 ("xtensa: enable KCSAN")
to make linker happy allthought they are not meant to be used at all.
KCSAN core has been fixed to not require them anymore on
32 bits architectures.
Then they can be removed.

gcc-13 may generate calls for __bswap{si,di}2. This breaks the kernel
build when optimization for size is selected. Add __bswap{si,di}2
helpers to fix that.

xtensa gcc-13 has changed multiplication handling and may now use
__umulsidi3 helper where it used to use __muldi3. As a result building
the kernel with the new gcc may fail with the following error:
linux/init/main.c:1287: undefined reference to `__umulsidi3'
Fix the build by providing __umulsidi3 implementation for xtensa.

Prefix arch-specific barrier macros with '__' to make use of instrumented
generic macros.
Prefix arch-specific bitops with 'arch_' to make use of instrumented
generic functions.
Provide stubs for 64-bit atomics when building with KCSAN.
Disable KCSAN instrumentation in arch/xtensa/boot.

Don't rely on libgcc presence, build own versions of the helpers with
correct ABI.
