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

[Stephen Rothwell]

Hi all,

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

  arch/arm64/include/asm/kvm_coproc.h
  arch/arm64/kvm/handle_exit.c

between commit:

  74cc7e0c35c1 ("KVM: arm64: clean up redundant 'kvm_run' parameters")

from the kvm tree and commits:

  6b33e0d64f85 ("KVM: arm64: Drop the target_table[] indirection")
  750ed5669380 ("KVM: arm64: Remove the target table")
  3a949f4c9354 ("KVM: arm64: Rename HSR to ESR")

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.
