Subject: [PATCH] i386: define the AMD 'virt-ssbd' CPUID feature bit
 (CVE-2018-3639)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

AMD Zen expose the Intel equivalant to Speculative Store Bypass Disable
via the 0x80000008_EBX[25] CPUID feature bit.

This needs to be exposed to guest OS to allow them to protect
against CVE-2018-3639.
