Please rework this against:

Add a few new AVX512 instruction groups/features for enumeration in
/proc/cpuinfo: AVX512_VBMI2, GFNI, VAES, VPCLMULQDQ, AVX512_VNNI,
AVX512_BITALG.
Clear the flags in fpu_xstate_clear_all_cpu_caps().
CPUID.(EAX=7,ECX=0):ECX[bit 6] AVX512_VBMI2
CPUID.(EAX=7,ECX=0):ECX[bit 8] GFNI

This is alread
Modify cpufeatures.h to add new AVX512 instruction groups/features
for enuermation in /proc/cpuinfo: AVX512IFMA and AVX512VBMI
Also modify the xstate.c to clear the flags in
fpu__xstate_clear_all_cpu_caps().
CPUID.(EAX=7,ECX=0):EBX[bit 21] AVX512IFMA
