make C=2

instead of the two-step process:
| Do a kernel make with "make C=1" to run sparse on all the C files that get
| recompiled, or use "make C=2" to run sparse on the files whether they need to
| be recompiled or not. The latter is a fast way to check the whole tree if you
| have already built it.

rm arch/arm/mach-omap2/*.o;make C=1 arch/arm/mach-omap2/ 2>Kerr;make C=2 arch/arm/mach-omap2/ 2>Kerr1;diff Kerr Kerr1

Kinda interesting to note that C=2 does'nt list all potential gcc warnings :( if one wanted a collated list of all warnings, rm .../*.o helps I guess.
