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. Linus
