Ingo Molnar 0915c4e89d sched: batch sleeper bonus 
batch up the sleeper bonus sum a bit more. Anything below
sched-granularity is too small to make a practical difference
anyway.

this optimization reduces the math in high-frequency scheduling
scenarios.

Ingo Molnar 6cfb0d5d06 [PATCH] sched: reduce debug code 
move the rest of the debugging/instrumentation code to under
CONFIG_SCHEDSTATS too. This reduces code size and speeds code up:

    text    data     bss     dec     hex filename
   33044    4122      28   37194    914a sched.o.before
   32708    4122      28   36858    8ffa sched.o.after

Ingo Molnar 8179ca23d5 [PATCH] sched: use schedstat_set() API 
make use of the new schedstat_set() API to eliminate two #ifdef sections.

No functional changes:

    text    data     bss     dec     hex filename
   29009    4122      28   33159    8187 sched.o.before
