Merge tag 'powerpc-5.7-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
- a revert of a recent change to the PTE bits for 32-bit BookS, which
broke swap.
- a "fix" to disable STRICT_KERNEL_RWX for 64-bit in Kconfig, as it's
causing crashes for some people.
Thanks to Christophe Leroy and Rui Salvaterra.
