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/sysreg.h

between commit:

  79d82cbcbb3d ("arm64/kexec: Test page size support with new TGRAN range values")

from the arm64 tree and commit:

  b31578f62717 ("arm64/mm: Define ID_AA64MMFR0_TGRAN_2_SHIFT")

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
