208 * For the user cases we used to use the %asi register, but
209 * it turns out that the "wr xxx, %asi" costs ~5 cycles, so
210 * now we use immediate ASI loads and stores instead. Kudos
211 * to Greg Onufer for pointing out this performance anomaly.
212 *
213 * Further note that we cannot use the g2, g4, g5, and g7 alternate
214 * globals in the spill routines, check out the save instruction in
215 * arch/sparc64/kernel/etrap.S to see what I mean about g2, and
216 * g4/g5 are the globals which are preserved by etrap processing
217 * for the caller of it. The g7 register is the return pc for
218 * etrap. Finally, g6 is the current thread register so we cannot
219 * us it in the spill handlers either. Most of these rules do not
220 * apply to fill processing, only g6 is not usable.
