232 /* Before touching these macros, you owe it to yourself to go and
233 * see how arch/sparc64/kernel/winfixup.S works... -DaveM
234 *
235 * For the user cases we used to use the %asi register, but
236 * it turns out that the "wr xxx, %asi" costs ~5 cycles, so
237 * now we use immediate ASI loads and stores instead. Kudos
238 * to Greg Onufer for pointing out this performance anomaly.
239 *
240 * Further note that we cannot use the g2, g4, g5, and g7 alternate
241 * globals in the spill routines, check out the save instruction in
242 * arch/sparc64/kernel/etrap.S to see what I mean about g2, and
243 * g4/g5 are the globals which are preserved by etrap processing
244 * for the caller of it. The g7 register is the return pc for
245 * etrap. Finally, g6 is the current thread register so we cannot
246 * us it in the spill handlers either. Most of these rules do not
247 * apply to fill processing, only g6 is not usable.
