  powerpc/mm: Mark __init memory no-execute when STRICT_KERNEL_RWX=y (2017-07-18 19:54:24 +1000)

----------------------------------------------------------------
powerpc fixes for 4.13 #3

A handful of fixes, mostly for new code.

Some reworking of the new STRICT_KERNEL_RWX support to make sure we also remove
executable permission from __init memory before it's freed.

A fix to some recent optimisations to the hypercall entry where we were
clobbering r12, this was breaking nested guests (PR KVM).

A fix for the recent patch to opal_configure_cores(). This could break booting
on bare metal Power8 boxes if the kernel was built without
CONFIG_JUMP_LABEL_FEATURE_CHECK_DEBUG.

And finally a workaround for spurious PMU interrupts on Power9 DD2.

Thanks to:
  Nicholas Piggin, Anton Blanchard, Balbir Singh.
