Linus Torvalds 0ba09b1733 Revert "mm: align larger anonymous mappings on THP boundaries" 
This reverts commit f35b5d7d67.

It has been reported to cause huge performance regressions on some loads
(will-it-scale.per_process_ops, but also building the kernel with
clang).

The commit did speed up gcc builds by a small amount, so it's not an
unambiguous regression, but until the big regressions are understood,
let's revert it.
