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/msr-index.h

between commit:

  0c5caea762de3 ("perf/x86: Add PERF_CAP_PEBS_TIMING_INFO flag")

from the tip tree and commit:

  cdfed9370b96a ("KVM: x86/pmu: Move PMU_CAP_{FW_WRITES,LBR_FMT} into msr-index.h header")

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.
