From a8f8001b386fe2eeb885121ae0f2b748ddf8e1f7 Mon Sep 17 00:00:00 2001 From: jhb Date: Fri, 14 Jan 2005 20:13:04 +0000 Subject: - Remove some OBE comments regarding cpu_exit(). cpu_exit() is no longer the last action of kern_exit(). Instead, it is a MD callout to cleanup per-process state during exit. - Add notes of concern to Alpha and ia64 about the possible need to drop fp state in cpu_thread_exit() rather than in cpu_exit() since it is per-thread state rather than per-process. --- sys/powerpc/aim/vm_machdep.c | 7 ------- 1 file changed, 7 deletions(-) (limited to 'sys/powerpc/aim') diff --git a/sys/powerpc/aim/vm_machdep.c b/sys/powerpc/aim/vm_machdep.c index acd8645..654a4be 100644 --- a/sys/powerpc/aim/vm_machdep.c +++ b/sys/powerpc/aim/vm_machdep.c @@ -182,13 +182,6 @@ cpu_set_fork_handler(td, func, arg) cf->cf_arg0 = (register_t)arg; } -/* - * cpu_exit is called as the last action during exit. - * We release the address space of the process, block interrupts, - * and call switch_exit. switch_exit switches to proc0's PCB and stack, - * then jumps into the middle of cpu_switch, as if it were switching - * from proc0. - */ void cpu_exit(td) register struct thread *td; -- cgit v1.1
