Modified files: sys/arch/hppa/hppa: pmap.c Log message: Be more agressive in flusing the cache. In addition to flushing the instruction cache, also purge TLB entries. The PA-RISC 2.0 architecture says that cache lines may be moved in when a translation exists even if no access is done. This might have been hurting us badly since we create illegal aliases in pmap_zero_page() and pmap_copy_page(). Probably not perfect yet, and perhaps a bit of a sledgehammer, but it makes PA-RISC 2.0 machines stable again.
