KVM: SVM: ignore type when setting segment registers
Commit 19bca6a ("KVM: SVM: Fix cross vendor migration issue with unusable bit") added checking type when setting unusable. So unusable can be set if present is 0 OR type is 0. According to the AMD processor manual, long mode ignores the type value in segment descriptor. And type can be 0 if it is read-only data segment. Therefore type value is not related to unusable flag. This patch is based on linux-next v4.12.0-rc3. Signed-off-by: Gioh Kim <gi-oh.kim@profitbricks.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
