Hi Peter,
There are lots of hardcoding of -20 and 19 in kernel to represent
minimum and maximum of nice value currently. This patch set define three
macros in prio.h and replace some of the hardcoding with them.

Please help to take a look at it, thanx :)

sched: Prio: Use DEFAULT_PRIO to define NICE_TO_PRIO and PRIO_TO_NICE.
sched: prio: Add 3 macros of MAX_NICE, MIN_NICE and NICE_WIDTH in
prio.h.
sched: prio: Use NICE_WIDTH macro to avoid using of hard coding of 40
and 20 in prio.h.
sched: prio: Add spaces before and after operator of '-'.
rcu: Use MAX_NICE to replace hard coding of 19.
sched: Replace hardcoding of -20 and 19 with MIN_NICE and MAX_NICE.
