[Nick Hudson <skrll%netbsd.org@localhost>]

Module Name:    src
Committed By:   skrll
Date:           Sat Jan 12 20:50:24 UTC 2008

Modified Files:
        src/sys/arch/arm/arm32: cpuswitch.S locore.S vm_machdep.c
        src/sys/arch/arm/include/arm32: frame.h

Log Message:
Push a switchframe in dumpsys and cpu_switchto, but as dumpsys calls
other funcs a switchframe needs to be a multiple of 8 bytes. Stash sp as
well in the switchframe to bump it to 24bytes.

Setup the switchframe appropriately in cpu_lwp_fork.

Remove savectx - nothing uses it.

All of this make gdb's life much easier when dealing with crash dumps and
live kernels.
