224  *
225  * For the user cases we used to use the %asi register, but
226  * it turns out that the "wr xxx, %asi" costs ~5 cycles, so
227  * now we use immediate ASI loads and stores instead.  Kudos
228  * to Greg Onufer for pointing out this performance anomaly.
229  *
230  * Further note that we cannot use the g2, g4, g5, and g7 alternate
231  * globals in the spill routines, check out the save instruction in
232  * arch/sparc64/kernel/etrap.S to see what I mean about g2, and
233  * g4/g5 are the globals which are preserved by etrap processing
234  * for the caller of it.  The g7 register is the return pc for
235  * etrap.  Finally, g6 is the current thread register so we cannot
236  * us it in the spill handlers either.  Most of these rules do not
237  * apply to fill processing, only g6 is not usable.
