CVS commit: [yamt-idlelwp] src/sys/arch/i386/i386

[Andrew Doran <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Thu Mar 29 19:00:25 UTC 2007

Modified Files:
        src/sys/arch/i386/i386 [yamt-idlelwp]: locore.S

Log Message:
- Tidy up slightly: remove pointless #ifdefs, make function descriptions
  consistent, remove checks for options that were removed 4+ years ago, ...
- Don't reload %cr0 or check for RAS if switching to a kthread.
- Don't try dropping the ipl using "movl $IPL_SCHED,CPUVAR(ILEVEL)". Causes
  deadlocks because the later drop of priority (possibly by mi_switch) can
  fail to notice pending IPIs. Just leave the level at IPL_IPI (for a very
  short time) at let it be dropped in mi_switch(). Spotted by yamt@.
