* CVE-2019-15807: Denial-of-service when discovering expander in SAS Domain

A logic error when discovering expander in SAS Domain Transport
Attributes fails could lead to a kernel assert. A local attacker could
use this flaw to cause a denial-of-service.

* Improved fix to CVE-2019-1125: Information leak in kernel entry code when
swapping GS.

The original CVE-2019-1125 did not correctly handle late microcode
updates resulting in a missing mitigation if the microcode was loaded
after boot time.
