1/*
2 * include/asm-parisc/prefetch.h
3 *
4 * PA 2.0 defines data prefetch instructions on page 6-11 of the Kane book.
5 * In addition, many implementations do hardware prefetching of both
6 * instructions and data.
7 *
8 * PA7300LC (page 14-4 of the ERS) also implements prefetching by a load
9 * to gr0 but not in a way that Linux can use. If the load would cause an
10 * interruption (eg due to prefetching 0), it is suppressed on PA2.0
11 * processors, but not on 7300LC.
