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

Hi all,

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

  arch/arm64/mm/proc.S

between commit:

  49b3cf035edc ("kasan: arm64: set TCR_EL1.TBID1 when enabled")

from the arm64 tree and commit:

  68cd215d6529 ("arm64: kasan: allow enabling in-kernel MTE")

from the akpm tree.

I fixed it up (I think, 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
