[PATCH 0/4] x86, CPU, AMD: Cleanup AMD-specific MSR-rw users

From: Borislav Petkov <borislav.petkov [at] amd>

Ok,

the following patchset should take care of all the {rd,wr}msrl_amd_safe
headaches we had this week. After it is applied, the AMD-specific
variants become private to amd.c and issue a warning when used on
anything else beside K8.

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

Thanks.

Looks good. This can be for 3.6, right (no immediate urgency)?

None on arch/x86/ - simply correctness fixes.

And I'm assuming since you took Konrad's patch, there are no pending
issues for xen either.

So yeah, this can wait for 3.6, IMHO.

Thanks.
