Merge branch 'x86-nuke386-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull "Nuke 386-DX/SX support" from Ingo Molnar:
"This tree removes ancient-386-CPUs support and thus zaps quite a bit
of complexity:
24 files changed, 56 insertions(+), 425 deletions(-)
... which complexity has plagued us with extra work whenever we wanted
to change SMP primitives, for years.
Unfortunately there's a nostalgic cost: your old original 386 DX33
system from early 1991 won't be able to boot modern Linux kernels
anymore. Sniff."
I'm not sentimental. Good riddance.
