2006-10-04	[PARISC] PA7200 also supports prefetch for read	Kyle McMartin	1	-0/+3
	It seems PA7200 processors also suppress traps on loads to %r0. This means we can prefetch for read on these cpus. Of course, we can't support prefetch for write, since that requires LOAD DOUBLEWORD which was added with PA2.0 Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2006-10-04	[PARISC] Untangle <asm/processor.h> header include mess	Kyle McMartin	1	-0/+36
	asm/processor.h on parisc wants spinlocks for cpuinfo, but linux/spinlock_types.h needs lockdep, and lockdep wants prefetch. This leads to a horrible circular dependancy, because <asm/processor.h> is including something which depends on things which are not defined until the end of the file. Kludge around this by moving prefetch related code into <asm/prefetch.h> and including it before <linux/spinlock_types.h>, however this is just a temporary solution until this mess can be cleaned up.
