Raw Normal View History

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!

/* delay.h: Linux delay routines on sparc64.
*
[SPARC64]: More sensible udelay implementation. Take a page from the powerpc folks and just calculate the delay factor directly. Since frequency scaling chips use a system-tick register, the value is going to be the same system-wide. Signed-off-by: David S. Miller <davem@davemloft.net>
