Subject: KVM: x86 emulator: pass destination type to ____emulate_2op()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b3b3d25a12986fb08666823db3e9a74649a71925;p=linux-beck.git

KVM: x86 emulator: pass destination type to ____emulate_2op()

We'll need it later so we can use a register for the destination.
