Kim Phillips fd470a8bee x86/cpu: Enable STIBP on AMD if Automatic IBRS is enabled ... Unlike Intel's Enhanced IBRS feature, AMD's Automatic IBRS does not provide protection to processes running at CPL3/user mode, see section "Extended Feature Enable Register (EFER)" in the APM v2 at https://bugzilla.kernel.org/attachment.cgi?id=304652 Explicitly enable STIBP to protect against cross-thread CPL3 branch target injections on systems with Automatic IBRS enabled. Also update the relevant documentation.
