 	src/tests/kernel/arch/x86: sig_fpu.c sig_fpu.h
 
 Log Message:
 Verify signal delivery preserves various FPU state.
 
 Should also test AVX512 but I'm not sure I have hardware handy to do
 this right now and qemu doesn't emulate it, as far as I know!  TBD.
 (Plus: there's umpteen different cpuid feature bits to consider,
 annoyingly, and that means a lot of manual reading to sort through
 them.)
