sparc: Convert some assembler over to linakge.h's ENTRY/ENDPROC Use those, instead of doing it all by hand. Signed-off-by: David S. Miller <davem@davemloft.net>

#include <linux/linkage.h>
Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
