# commit 0ba09b1733878afe838fe35c310715fda3d46428
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Revert "mm: align larger anonymous mappings on THP boundaries"
#     
#     This reverts commit f35b5d7d676e59e401690b678cd3cfec5e785c23.
#     
#     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.
