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.
