  powerpc/32s: fix booting with CONFIG_PPC_EARLY_DEBUG_BOOTX (2019-06-07 19:00:14 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.2 #4

One fix for a regression introduced by our 32-bit KASAN support, which broke
booting on machines with "bootx" early debugging enabled.

A fix for a bug which broke kexec on 32-bit, introduced by changes to the 32-bit
STRICT_KERNEL_RWX support in v5.1.

Finally two fixes going to stable for our THP split/collapse handling,
discovered by Nick. The first fixes random crashes and/or corruption in guests
under sufficient load.

Thanks to:
  Nicholas Piggin, Christophe Leroy, Aaro Koskinen, Mathieu Malaterre.
