Konrad Rzeszutek Wilk 254790a909 i386: Define AMD's no SSB mitigation needed. 
AMD future CPUs expose a mechanism to tell the guest that the
Speculative Store Bypass Disable is not needed and that the
CPU is all good.

This is exposed via the CPUID 8000_0008.EBX[26] bit.

See 124441_AMD64_SpeculativeStoreBypassDisable_Whitepaper_final.pdf
