Subject: linux-next: manual merge of the kvm tree with Linus' and the tip
 trees

Hi all,

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

  arch/x86/include/asm/cpufeatures.h

between commit:

  a89f040fa34e ("x86/cpufeatures: Add X86_BUG_CPU_INSECURE")

from Linus' tree, commit:

  76b043848fd2 ("x86/retpoline: Add initial retpoline support")

from the tip tree and commit:

  18c71ce9c882 ("x86/CPU/AMD: Add the Secure Encrypted Virtualization CPU feature")

from the kvm 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
