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!

/* Before touching these macros, you owe it to yourself to go and

|
* see how arch/sparc64/kernel/winfixup.S works... -DaveM
|
|
*
|
|
* For the user cases we used to use the %asi register, but
|
|
* it turns out that the "wr xxx, %asi" costs ~5 cycles, so
|
|
* now we use immediate ASI loads and stores instead. Kudos
|
|
* to Greg Onufer for pointing out this performance anomaly.
|
|
*
|
|
* Further note that we cannot use the g2, g4, g5, and g7 alternate
|
|
* globals in the spill routines, check out the save instruction in
|
|
* arch/sparc64/kernel/etrap.S to see what I mean about g2, and
|
|
* g4/g5 are the globals which are preserved by etrap processing
|
|
* for the caller of it. The g7 register is the return pc for
|
|
* etrap. Finally, g6 is the current thread register so we cannot
|
|
* us it in the spill handlers either. Most of these rules do not
|
|
* apply to fill processing, only g6 is not usable.
