Subject: KVM: x86 emulator: fix JMP_REL
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e826ec9ae2baf9980402e85f0bbe1dac53ceb110;p=linux-beck.git

KVM: x86 emulator: fix JMP_REL

Change JMP_REL to call to register_address_increment(): the operands size
should not effect the calculation of the eip, instead the ad_bytes should
affect it.
