        src/sys/contrib/dev/ath/netbsd: ah_osdep.c

Log Message:
The Atheros HAL on MIPS uses %s7 as a general purpose register, but the
rest of the kernel uses it to store the value of curlwp. Sam won't
recompile the HAL for us (fair enough), and we can't modify the HAL
to use another register because doing so could put us in breach of
the license (v. crappy). So, do a save/set/restore on %s7 in KernIntr()
and in the stubs that the HAL uses to call back into the kernel.
