/proc/cpuinfo cpu database?

[Andrew Jorgensen]

Not absolutely sure, but I think the flag "lm" in /proc/cpuinfo may
indicate that you've got a 64-bit capable processor.
/usr/include/asm-i386/cpufeature.h has a line that says

#define X86_FEATURE_LM          (1*32+29) /* Long Mode (x86-64) */

Looking on google it seems that Long Mode is indeed 64-bit mode.
(Differing from Real Mode 16-bit and Protected Mode 32-bit)
