[linux-vr-cvsupdate] Update to module linux

[Michael K. <mf...@us...>]

Update of /cvsroot/linux-vr/linux/arch/mips/vr41xx
In directory slayer.i.sourceforge.net:/tmp/cvs-serv27021

Modified Files:
	serial.c tpanel.c 
Log Message:
Make all read-modify-write accesses to VR41XX_CMUCLKMSK interrupt-safe,
since the serial driver can write that register at interrupt time if serial
console is configured (so can the touch panel driver for VR4181).
