+	 *
+	 * We used to clear some PSR bits here but that requires slow
+	 * serialization.  Fortuntely, that isn't really necessary.
+	 * The rationale is as follows: we used to clear bits
+	 * ~PSR_PRESERVED_BITS in PSR.L.  Since
+	 * PSR_PRESERVED_BITS==PSR.{UP,MFL,MFH,PK,DT,PP,SP,RT,IC}, we
+	 * ended up clearing PSR.{BE,AC,I,DFL,DFH,DI,DB,SI,TB}.
+	 * However,
+	 *
+	 * PSR.BE : already is turned off in __kernel_syscall_via_epc()
+	 * PSR.AC : don't care (kernel normally turns PSR.AC on)
+	 * PSR.I  : already turned off by the time fsys_bubble_down gets
+	 *	    invoked
+	 * PSR.DFL: always 0 (kernel never turns it on)
+	 * PSR.DFH: don't care --- kernel never touches f32-f127 on its own
+	 *	    initiative
+	 * PSR.DI : always 0 (kernel never turns it on)
+	 * PSR.SI : always 0 (kernel never turns it on)
+	 * PSR.DB : don't care --- kernel never enables kernel-level
+	 *	    breakpoints
+	 * PSR.TB : must be 0 already; if it wasn't zero on entry to
+	 *          __kernel_syscall_via_epc, the branch to fsys_bubble_down
+	 *          will trigger a taken branch; the taken-trap-handler then
+	 *          converts the syscall into a break-based system-call.
