Subject: [GIT PULL] Please pull powerpc/linux.git powerpc-5.18-1 tag
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
Hi Linus,
Please pull powerpc updates for 5.18.
Livepatch support for 32-bit is probably the standout new feature, otherwise mostly just
lots of bits and pieces all over the board.
There's a series of commits cleaning up function descriptor handling, which touches
a few other arches as well as LKDTM. It has acks from Arnd, Kees and Helge.
There's no conflicts with your current tree. There are two minor conflicts in linux-next,
one with the nvdimm tree[1] and the other with the tip tree[2].
cheers

powerpc/pseries: Fix use after free in remove_phb_dynamic() (2022-03-21 13:17:47 +1100)
- ------------------------------------------------------------------
powerpc updates for 5.18
- Enforce kernel RO, and implement STRICT_MODULE_RWX for 603.
- Add support for livepatch to 32-bit.
- Implement CONFIG_DYNAMIC_FTRACE_WITH_ARGS.
- Merge vdso64 and vdso32 into a single directory.
- Fix build errors with newer binutils.
- Add support for UADDR64 relocations, which are emitted by some toolchains. This allows
powerpc to build with the latest lld.
- Fix (another) potential userspace r13 corruption in transactional memory handling.
- Cleanups of function descriptor handling & related fixes to LKDTM.
