Umm, and this is different how from clearing the PSE bit when we decide
not to use large-page support?

See arch/x86/kernel/setup_32.c: parse_mem() for an example.

Rene - you have valid points (ie that patches were NAK'ed etc and you
might have wanted better changelog entries), but trust me, this one is not
one of them. /proc/cpuinfo and the kernel clearing feature bits is
_normal_. It's how it has always been.
