13 * into user reg-file when traded task rets to user space.
40 * we need to explicitly do this. The problem in macros
49 * Minor Surgery of Low Level ISR to make it SMP safe
80 * across sections (.vector to .text) we are guaranteed that 'j somewhere'
154 ; This is to avoid a potential L1-L2-L1 scenario
157 ; -preemption off IRQ, user task in syscall picked to run
158 ; -RTIE to userspace
167 ; need to check STATUS32_L2 to determine if L1 was active
208 ; User process needs to be killed with SIGBUS, but first need to get
209 ; out of the L2 interrupt context (drop to pure kernel mode) and jump
210 ; off to "C" code where SIGBUS in enqueued
233 ; icause1 needs to be read early, before calling tracing, which
234 ; can clobber scratch regs, hence use of stack to stash it
288 ; Very similar to ProtV handler case (6a) above, but avoids the extra checks
308 ; All 2 entry points to here already disable interrupts
314 # But irq tracer needs to be told now...
321 ; Note that we use realtime STATUS32 (not pt_regs->status32) to
344 ; so that sched doesn't move to new task, causing L1 to be delayed
346 ; things to what they were, before returning from L2 context
