From: Alexander Graf <[email protected]> MSR_EFER_SVME_MASK, MSR_VM_CR and MSR_VM_HSAVE_PA are set in KVM specific headers. Linux does have nice header files to collect EFER bits and MSR IDs, so IMHO we should put them there.
While at it, I also changed the naming scheme to match that of the other defines.
