This patch addresses CVE-2006-1056 (information leak from
fxsave/fxrstor on AMD CPUs) and also adjusts 64-bit handling so that
full 64-bit RIP/RDP values get saved/restored. More fine-grained
handling may be needed if 32-bit processes are expected to properly
see their selectors (native Linux doesn't currently do that either,
but there is a patch to adjust it there).

Original patch: Jan Beulich (based on Linux original by Andi Kleen)
