  lib/mpi: Fix building for powerpc with clang (2020-04-24 13:14:59 +1000)

Out of area changes:
lib/mpi/longlong.h	# 5990cdee689c lib/mpi: Fix building for powerpc with clang

- ------------------------------------------------------------------
powerpc fixes for 5.7 #3

 - 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.
