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
