The quilt patch titled Subject: mm: huge_memory: use !CONFIG_64BIT to relax huge page alignment on 32 bit machines has been removed from the -mm tree. Its filename was mm-huge_memory-use-config_64bit-to-relax-huge-page-alignment-on-32-bit-machines.patch

This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Yves-Alexis Perez reported commit 4ef9ad19e176 ("mm: huge_memory: don't force huge page alignment on 32 bit") didn't work for x86_32 [1]. It is because x86_32 uses CONFIG_X86_32 instead of CONFIG_32BIT.

!CONFIG_64BIT should cover all 32 bit machines.
