James Bottomley b3cb867481 [PARISC] fix panic on prefetch(NULL) on PA7300LC ... 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.
