rearnsha 2c48187673 Don't unmap page 0 when preparing to swap out a process. If the pmap 
is shared with another process (as can happen if vfork is being used),
then that other process will end up not having a page 0, which is bad
news indeed, since then there is no way back into the kernel.

Found this using a multi-ice box, so they are useful after all!

This seems to fix pr port-arm32/11921 and (possibly) kern/9859.

arm32_machdep.c Update pmap_update to now take the updated pmap as an argument. 2001-09-10 21:19:08 +00:00
ast.c
bcopy_page.S Patch in Richard E's changes to bcopy page, the loop doesn't need unrolling as much as it currently is due to the overhead of the load/stores taking most of the time. (profiling shows minimal time difference) 2001-08-11 12:44:42 +00:00
bcopyinout.S Note the alignment state of the stack. This is part of the work to get the stack 8byte aligned for ELF 2001-09-28 09:56:03 +00:00

spl.S Tweak spl functions a little, try to do something between an ldr and it's use. Not the greatest of gains but spl is called a lot it might add up. 2001-09-28 10:01:02 +00:00
