Jason A. Harmening 713841afb2 Add two new pmap functions: ... vm_offset_t pmap_quick_enter_page(vm_page_t m) void pmap_quick_remove_page(vm_offset_t kva) These will create and destroy a temporary, CPU-local KVA mapping of a specified page. Guarantees: --Will not sleep and will not fail. --Safe to call under a non-sleepable lock or from an ithread Restrictions: --Not guaranteed to be safe to call from an interrupt filter or under a spin mutex on all platforms --Current implementation does not guarantee more than one page of mapping space across all platforms. MI code should not make nested calls to pmap_quick_enter_page. --MI code should not perform locking while holding onto a mapping created by pmap_quick_enter_page The idea is to use this in busdma, for bounce buffer copies as well as virtually-indexed cache maintenance on mips and arm. NOTE: the non-i386, non-amd64 implementations of these functions still need review and testing.
