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