+;	For uatrap

+; nested traps and interrupts such as TLB miss, protection violation,
+; or Data Access Exception, and these trap handlers use the shared
+; Temp registers, we must maintain our own that are safe over user-
+; mode loads and stores.  The following must be assigned global
+; registers which are not used in INTR[0-3], TRAP[0-1], TLB miss,
+; TLB protection violation, or data exception trap handlers.
