mm: cleanup count_mthp_stat() definition
Patch series "Shmem mTHP controls and stats improvements", v3.
This is a small series to tidy up the way the shmem controls and stats are
exposed. These patches were previously part of the series at [2], but I
decided to split them out since they can go in independently.
This patch (of 2):
Let's move count_mthp_stat() so that it's always defined, even when THP is
disabled. Previously uses of the function in files such as shmem.c, which
are compiled even when THP is disabled, required ugly THP ifdeferry. With
this cleanup, we can remove those ifdefs and the function resolves to a
nop when THP is disabled.
I shortly plan to call count_mthp_stat() from more THP-invariant source
files.
