        src/sys/arch/x86/x86: fpu.c

Log Message:
Fix fpu_kern_enter in a softint that interrupted a softint.

We need to find the lwp that was originally interrupted to save its
fpu state.

With this, fpu-heavy programs (like firefox) are once again stable,
at least under modest stress testing, on systems configured to use
wifi with WPA2 and CCMP.
