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!

[SPARC64]: Need to clobber global reg vars in switch_to(). Otherwise the compiler can't see the things like the per-cpu area base register are changing. Signed-off-by: David S. Miller <davem@davemloft.net>

SPARC64: use generic percpu Sparc64 has a way of providing the base address for the per cpu area of the currently executing processor in a global register. Sparc64 also provides a way to calculate the address of a per cpu area from a base address instead of performing an array lookup.
