Revision d9592025000b3cf26c742f3505da7b83aedc26d5 authored by Yang Shi on 12 July 2024, 15:58:55 UTC, committed by Andrew Morton on 26 July 2024, 21:33:09 UTC 
mm: huge_memory: use !CONFIG_64BIT to relax huge page alignment on 32 bit machines
 
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.
