 222 /* Before touching these macros, you owe it to yourself to go and
 223  * see how arch/sparc64/kernel/winfixup.S works... -DaveM
 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.
