X-Git-Tag: v2.6.38-rc1~244^2~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=db8fcefaa704ccb40b6dcd24e3b75bad3ce7dde3;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git

KVM: move complete_insn_gp() into x86.c

move the complete_insn_gp() helper function out of the VMX part
into the generic x86 part to make it usable by SVM.
