Subject: amd svm: Do not touch (non-existent) attr and selector fields for GDTR
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~14192^2~62
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https://%22%22/%22http:/www.example.com/cgi/%22https:/%22%22?a=commitdiff_plain;h=7280aab36008a5c2b4605b61847907f75f05b2d0;p=xen.git

amd svm: Do not touch (non-existent) attr and selector fields for GDTR
and IDTR in the VMCB in svm_set_segment_register(). This is just for
clarity of code and to prevent any issues in the future.
