X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25391454e73e3156202264eb3c473825afe4bc94;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git KVM: VMX: don't clobber segment AR of unusable segments. Usability is returned in unusable field, so not need to clobber entire AR. Callers have to know how to deal with unusable segments already since if emulate_invalid_guest_state=true AR is not zeroed.
