nommu: fix build breakage
Commit 34e55232e59f7b19050267a05ff1226e5cd122a5 ("mm: avoid false sharing
of mm_counter") added sync_mm_rss() for syncing loosely accounted rss
counters. It's for CONFIG_MMU but sync_mm_rss is called even in NOMMU
enviroment (kerne/exit.c, fs/exec.c). Above commit doesn't handle it
well.
This patch changes
SPLIT_RSS_COUNTING depends on SPLIT_PTLOCKS && CONFIG_MMU
And for avoid unnecessary function calls, sync_mm_rss changed to be inlined
noop function in header file.
