Subject: KVM: Use the generic skip_emulated_instruction() in hypercall code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=510043da8582ad49d22a1e9a6b211e6ede10cd2e;p=mv-sheeva.git

KVM: Use the generic skip_emulated_instruction() in hypercall code

Instead of twiddling the rip registers directly, use the
skip_emulated_instruction() function to do that for us.
