Subject: [PATCH v1 01/26] tools/x86/kcpuid: Update bitfields to x86-cpuid-db v2.4
Update kcpuid's CSV file to version 2.4, as generated by x86-cpuid-db.
Summary of the v2.4 changes:
* Mark CPUID(0x80000001) EDX:23 bit, 'e_mmx', as not exclusive to
Transmeta since it is supported by AMD as well.
Signed-off-by: Ahmed S. Darwish <darwi@...utronix.de>
