Subject: [GIT PULL] x86, CPU, AMD: Cleanup AMD-specific MSR-rw users

Hi Peter,

so here are the final versions of the patches, as discussed. 3/4 has
lost the stable tag and all have received Konrad's Acked-by. Other than
that, 1ab46fd319bc takes care of the -stable issue for xen and Greg is
picking that one up. So all those should be queued for 3.6.

Please pull, thanks.

  x86, CPU, AMD: Deprecate AMD-specific MSR variants (2012-06-07 12:52:58 +0200)

----------------------------------------------------------------
x86, CPU, AMD: Cleanup AMD-specific MSR-rw users

This patchset takes care of all the {rd,wr}msrl_amd_safe headaches we
had wrt xen. After it is applied, the AMD-specific variants become
private to amd.c and issue a warning when used on anything else beside
K8 because they're supposed to be used only on K8.

This also contains the two patches from Andre which cleanup the PV-side
of things.
