Compilers are smart enough now a days and may not perform !!
at all I believe.. And so this patch is more about code clarity ..
I tried comparing results for ARM and got this with/without
this patch ..
$ size ../bexynos/kernel/sched/idle.o
text data bss dec hex filename
690 30 0 720 2d0 ../bexynos/kernel/sched/idle.o
Don't know if some architectures are using somewhat dumb
compilers which might result in better code with this patch :)
