Change 134532 by imp at imp_lighthouse on 2008/01/31 07:04:55

	Save 32-bits only on ISA_MIPS32.  Save 64 on MIPS64.  Even if you
	are running a 32-bit kernel, you'll need to save 64-bits of registers
	because the kernel dereferences 64-bit addresses when it is writing
	to the octeon hardware.  This is likely to be typical of all 64-bit
	machines, so base it off of ISA_MIPS64.
	
	There's a hack in types.h that uses ISA_MIPS64 to define a few things,
	but I'm not sure that's right since this file is exported to userland.
