[PATCH 0/2] Add support for FFXSR

[Alexander Graf <agraf@suse.de>]

AMD k10 includes support for the FFXSR feature, which leaves out
XMM registers on FXSAVE/FXSAVE when the EFER_FFXSR bit is set in
EFER.

This patchset enables support for the FFXSR feature in KVM, allowing
the VM to set the bit in EFER when the physical CPU and the guest's
CPUID allow it.

  Add EFER descriptions for FFXSR
