Fix breakage in NOMMU build
commit 34e55232e59f7b19050267a05ff1226e5cd122a5 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.
fixes Blackfin systems ...
