Merge tag 'powerpc-6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
- Support for configuring secure boot with user-defined keys on PowerVM
LPARs
- Simplify the replay of soft-masked IRQs by making it non-recursive
- Add support for KCSAN on 64-bit Book3S
- Improvements to the API & code which interacts with RTAS (pseries
firmware)
- Change 32-bit powermac to assign PCI bus numbers per domain by
default
- Some improvements to the 32-bit BPF JIT
- Various other small features and fixes
