For some of them it is questionable if there even exists functional specimens of the hardware" Geert Uytterhoeven apparently thought this was a April Fool's pull request ;) * 'x86-nuke-platforms-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, platforms: Remove NUMAQ x86, platforms: Remove SGI Visual Workstation x86, apic: Remove support for IBM Summit/EXA chipset x86, apic: Remove support for ia32-based Unisys ES7000 2014-03-11T17:16:18+00:00 Dave Jones davej@redhat.com 2014-03-10T23:32:22+00:00 urn:sha1:09df7c4c8097ca4a11393b1edd4997d786daad52 This was an optimization that made memcpy type benchmarks a little faster on ancient (Circa 1998) IDT Winchip CPUs. In real-life workloads, it wasn't even noticable, and I doubt anyone is running benchmarks on 16 year old silicon any more. Given this code has likely seen very little use over the last decade, let's just remove it.

As such, it is too unsupported now. Reported-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Link: http://lkml.kernel.org/r/20121128205203.05868eab@pyramind.ukuu.org.uk Signed-off-by: H.
