Pull powerpc fixes from Michael Ellerman:

 - Fix handling of PCI domains in /proc on 32-bit systems using the
   recently added support for numbering buses from zero for each domain.

 - A fix and a revert for some changes to use READ/WRITE_ONCE() which
   caused problems with KASAN enabled due to sanitisation calls being
   introduced in low-level paths that can't cope with it.

 - Fix build errors on 32-bit caused by the syscall table being
   misaligned sometimes.

 - Two fixes to get IBM Cell native machines booting again, which had
   bit-rotted while my QS22 was temporarily out of action.

 - Fix the papr_scm driver to not assume the order of events returned by
   the hypervisor is stable, and a related compile fix.
