204 /* Before touching these macros, you owe it to yourself to go and
205 * see how arch/sparc64/kernel/winfixup.S works... -DaveM
206 *
207 * For the user cases we used to use the %asi register, but
208 * it turns out that the "wr xxx, %asi" costs ~5 cycles, so
209 * now we use immediate ASI loads and stores instead. Kudos
210 * to Greg Onufer for pointing out this performance anomaly.
211 *
212 * Further note that we cannot use the g2, g4, g5, and g7 alternate
213 * globals in the spill routines, check out the save instruction in
214 * arch/sparc64/kernel/etrap.S to see what I mean about g2, and
215 * g4/g5 are the globals which are preserved by etrap processing
216 * for the caller of it. The g7 register is the return pc for
217 * etrap. Finally, g6 is the current thread register so we cannot
218 * us it in the spill handlers either. Most of these rules do not
219 * apply to fill processing, only g6 is not usable.
