2012-05-16[PARISC] fix panic on prefetch(NULL) on PA7300LCJames Bottomley1-1/+6
Due to an errata, the PA7300LC generates a TLB miss interruption even on the prefetch instruction. This means that prefetch(NULL), which is supposed to be a nop on linux actually generates a NULL deref fault. Fix this by testing the address of prefetch against NULL before doing the prefetch.
