I was wondering where I can find out what the cpuinfo flags mean, when you
type 'cat /proc/cpuinfo'. The proc man page was not very helpful in this
regard. Other than 'fpu' I have no idea what they mean.

1. fix up newer x86 cpuinfo flags.
According to Intel document 24161823.pdf[*] page 18, 'tm2' is misdefined.
Its bit 7 not, bit 8. Also add the missing 'EST' (Enhanced Speedstep Technology)
bit, and use the correct Intel terminology for the context ID bit.
