Merge tag 'powerpc-6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
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
