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

| * | |
| * 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. | |
