Merge branch 'x86-nuke-platforms-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 old platform removal from Peter Anvin:
"This patchset removes support for several completely obsolete
platforms, where the maintainers either have completely vanished or
acked the removal. 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
