Re: [RFC 00/15] x86_64: Optimize percpu accesses

> x86_64 are small systems? For 64 bit use one would expect 4GB of memory.

Anything over 1G where 32bit runs out of lowmem starts to be a win.
Plus sometimes it just doesn't make sense to use a 32bit kernel.

Expecting 4GB of real memory seems silly.
