You dropped the generic-y += kvm_para.h for arm64 & c6x, but not for
unicore, avr32 & ia64 patch, which seems a bit inconsistent. Was there
some reason behind that?

AFACT the non-uapi kvm_para.h is needed (e.g. by using the generic
non-uapi one) by kernel/watchdog.c for
kvm_check_and_clear_guest_paused(), so all arches should have at least
generic-y += kvm_para.h (or their own one) for non-uapi, even if they
have a uapi one too.

For UAPI, they're presumably only needed for architectures which support
KVM (s390, ia64, arm, powerpc, arm64, mips, x86 all provide an asm/kvm.h).

Is that right? Clearly there's some cleanup to do for kvm_para.h (which
is what made me look at the header issues previously).

Cheers
James
