Peter Zijlstra 3289bdb429 sched: Move the loadavg code to a more obvious location

I could not find the loadavg code.. turns out it was hidden in a file
called proc.c. It further got mingled up with the cruft per rq load
indexes (which we really want to get rid of).

Move the per rq load indexes into the fair.c load-balance code (that's
the only thing that uses them) and rename proc.c to loadavg.c so we
can find it again.

According to Alan Modra alan@linuxcare.com.au, the -fno-omit-frame-pointer is

needed for x86 only. Why this used to be enabled for all architectures is beyond

me. I suspect most platforms don't need this, but until we know that for sure

I turn this off for IA-64 only. Andreas Schwab says it's also needed on m68k

to get a correct value for the wait-channel (WCHAN in ps). --davidm
