Subject: KVM: SVM: Initialize fpu_active in init_vmcb()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bff7827479ed004c0394e6e7b35ae601bb1a97ad;p=linux-beck.git

KVM: SVM: Initialize fpu_active in init_vmcb()

init_vmcb() sets up the intercepts as if the fpu is active, so initialize it
there.  This avoids an INIT from setting up intercepts inconsistent with
fpu_active.
