+x86: fix information leak on AMD CPUs
+
+The fix for XSA-52 was wrong, and so was the change synchronizing that
+new behavior to the FXRSTOR logic: AMD's manuals explictly state that
+writes to the ES bit are ignored, and it instead gets calculated from
+the exception and mask bits (it gets set whenever there is an unmasked
+exception, and cleared otherwise). Hence we need to follow that model
+in our workaround.
+
+This is XSA-172.
+
+The first hunk (xen/arch/x86/i387.c:fpu_fxrstor) is CVE-2016-3159.
+The second hunk (xen/arch/x86/xstate.c:xrstor) is CVE-2016-3158.
