Jérôme Duval c7360f4b02 kernel/x86_64: on context switch, load defaults in fpu control and mxcsr
after a0131eaae2884fdced27158c3d34732d1656aca9 mxcsr was possibly also incorrect.
fpu control and mxcsr will be restored with fxrstor/xrstor.
no need to clear pending exceptions on #MF
fix #18656 (and #18624 after reverting).
