[PATCH] i386/x86-64: Fix x87 information leak between processes (CVE-2006-1056)

AMD K7/K8 CPUs only save/restore the FOP/FIP/FDP x87 registers in FXSAVE when an exception is pending. This means the value leak through context switches and allow processes to observe some x87 instruction state of other processes.
This was actually documented by AMD, but nobody recognized it as being different from Intel before.

関係あるのは AMD K7/K8 の人だけかな。
