From: Ingo Molnar <mingo@xxxxxxx>
Subject: sched: clean up fallout of recent changes
this patch cleans up some of the impact of recent (and not so recent)
scheduler changes:
- turning macros into nice inline functions
- sanitizing and unifying variable definitions
- whitespace, style consistency, 80-lines, comment correctness, spelling
and curly braces police
still boots fine, and due to the macro hell and variable placement
simplifications there's even 26 bytes of .text saved:
text data bss dec hex filename
25510 4153 192 29855 749f sched.o.before
25484 4153 192 29829 7485 sched.o.after
goes to the end of the scheduler queue in -mm (sans
sched2-sched-domain-sysctl.patch).
