[PATCH 29/43] KVM: SVM: Tweak order of cr0/cr4/efer writes at RESET/INIT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hoist svm_set_cr0() up in the sequence of register initialization during
vCPU RESET/INIT, purely to match VMX so that a future patch can move the
sequences to common x86.
