Subject: linux-next: manual merge of the kvm-arm tree with the arm64 tree

Hi all,

Today's linux-next merge of the kvm-arm tree got a conflict in:

  arch/arm64/include/asm/cpufeature.h

between commit:

  48ce8f80f590 ("arm64: irqflags: Introduce explicit debugging for IRQ priorities")

from the arm64 tree and commit:

  c118bbb52743 ("arm64: KVM: Propagate full Spectre v2 workaround state to KVM guests")

from the kvm-arm tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
