Subject: mm/shmem: fix build without THP
Some optimizers don't notice that shmem_punch_compound() is always true
(PageTransCompound() being false) without CONFIG_TRANSPARENT_HUGEPAGE=3Dy:
use IS_ENABLED to help them to avoid the BUILD_BUG inside HPAGE_PMD_NR.
Link: http://lkml.kernel.org/r/alpine.LSU.2.11.2004142339170.10035@eggly.anvils
Fixes: 71725ed10c40 ("mm: huge tmpfs: try to split_huge_page() when punchin=
g hole")
