# commit 14d7c92f8df9c0964ae6f8b813c1b3ac38120825
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Mon Jun 17 12:57:03 2024 -0700

#     Revert "mm: mmap: allow for the maximum number of bits for randomizing mmap_base by default"
#     
#     This reverts commit 3afb76a66b5559a7b595155803ce23801558a7a9.
#     
#     This was a wrongheaded workaround for an issue that had already been
#     fixed much better by commit 4ef9ad19e176 ("mm: huge_memory: don't force
#     huge page alignment on 32 bit").
#     
#     Asking users questions at kernel compile time that they can't make sense
#     of is not a viable strategy.  And the fact that even the kernel VM
#     maintainers apparently didn't catch that this "fix" is not a fix any
#     more pretty much proves the point that people can't be expected to
#     understand the implications of the question.
#     
#     It may well be the case that we could improve things further, and that
#     __thp_get_unmapped_area() should take the mapping randomization into
#     account even for 64-bit kernels.  Maybe we should not be so eager to use
#     THP mappings.
#     
#     But in no case should this be a kernel config option.
