Subject: KVM: Remove unused 'instruction_length'
X-Git-Tag: v3.12-rc1~30556^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2ff81f70b56dc1cdd3bf2f08414608069db6ef1a;p=kernel%2Fkernel-generic.git

KVM: Remove unused 'instruction_length'

As we no longer emulate in userspace, this is meaningless.  We don't
compute it on SVM anyway.
