Log Message:
Update for cpuid flags:

 - The table 11 was changed from CPUID 0x0f leaf 0 %edx to a Linux mapping.
 - The table 12 was changed from CPUID 0x0f leaf 1 %edx to CPUID 0x07 leaf 1
   %edx. Print avx_vnni and avx512_bf16.
 - Print cppc, enqcmd and arch_lbr.
 - Modify linux mapping. No used on NetBSD.
