Merge tag 'powerpc-5.7-3' of git://git./linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:

 - One important fix for a bug in the way we find the cache-line size
   from the device tree, which was leading to the wrong size being
   reported to userspace on some platforms.

 - A fix for 8xx STRICT_KERNEL_RWX which was leaving TLB entries around
   leading to a window at boot when the strict mapping wasn't enforced.

 - A fix to enable our KUAP (kernel user access prevention) debugging on
   PPC32.

 - A build fix for clang in lib/mpi.

Thanks to: Chris Packham, Christophe Leroy, Nathan Chancellor, Qian Cai.
