fredette 02f0a2cf44 Significant pmap changes to no longer rely on the "U-bit" (TLB_UNCACHEABLE) ... to deal with aliasing of regular memory pages, because many processors don't support it. Now, the pmap marks all mappings of a page that has any non-equivalent aliasing and any writable mapping, and the fault handlers watch for this and flush other mappings out of the TLB and cache before (re)entering a conflicting mapping. When a page has non-equivalent aliasing, only one writable mapping at a time may be in the TLB and cache. If no writable mapping is in the TLB and cache, any number of read-only mappings may be. The PA7100LC/PA7300LC fault handlers have not been converted yet.		2002-08-11 22:29:07 +00:00
