Subject: linux-next: manual merge of the kvm-x86 tree with the tip tree

Hi all,

Today's linux-next merge of the kvm-x86 tree got a conflict in:

  arch/x86/include/asm/cpufeatures.h

between commits:

  a018d2e3d4b1 ("x86/cpufeatures: Add Architectural PerfMon Extension bit")
  660569472dd7 ("x86/cpufeature: Add the CPU feature bit for LKGS")

from the tip tree and commit:

  751b1e1ee8e9 ("x86/cpufeatures: Add macros for Intel's new fast rep string features")

from the kvm-x86 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
