Hi all,

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

  arch/arm64/kernel/cpufeature.c

between commits:

  143ba05d867a ("arm64: capabilities: Prepare for fine grained capabilities=
")
  12eb369125ab ("arm64: cpufeature: Avoid warnings due to unused symbols")

from the arm64 tree and commit:

  a1efdff442ec ("arm64: cpufeatures: Drop the ARM64_HYP_OFFSET_LOW feature =
flag")

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
