[Xen-devel] [PATCH 4/5] svm: implement CR access part of DecodeAssist



Newer SVM implementations (Bulldozer) now give the used general
purpose register on a MOV-CR intercept explictly. This avoids
fetching and decoding the instruction from guest's memory and speeds
up some Windows guest, which exercise CR8 quite often.
