Now that powerpc has removed its use of MSG_ALL_BUT_SELF and MSG_ALL
all these MSG_ flags are unused.

To be merged by powerpc with the series posted to linuxppc-dev

After the previous 2 patches, grep shows the following false hits (from
partial symbol matches):

find . -name .git -prune -o -name .pc -prune -o -name patches -prune -o -type f|
 xargs grep -E 'MSG_(ALL|RESCHEDULE|CALL_FUNCTION|INVALIDATE_TLB|STOP_CPU)'

	XFRM_MSG_ALLOCSPI (include/linux/xfrm.h, net/xfrm/xfrm_user.c)
	CHANNELMSG_ALLOFFERS_DELIVERED (drivers/staging/hv/)
	PPC_MSG_CALL_FUNCTION, PPC_MSG_RESCHEDULE (arch/powerpc/)
	SMP_MSG_RESCHEDULE (arch/sh/)
