bus_dmamem_map() maps DMA safe memory, which is usually one or more
...
managed pages, into KVA space. Since the pages are managed, we should
use pmap_enter(), not pmap_kenter_pa().
Also, when entering the mappings, enter with an access_type of
VM_PROT_READ | VM_PROT_WRITE. We do this for a couple of reasons:
(1) On systems that have H/W mod/ref attributes, the hardware
may not be able to track mod/ref done by a bus master.
(2) On systems that have to do mod/ref emulation, this prevents
a mod/ref page fault from potentially happening while in an
interrupt context, which can be problematic.
This latter change is fairly important if we ever want to be able to
transfer DMA-safe memory pages to anonymous memory objects; we will need
to know that the pages are modified, or else data could be lost!
Note that while the pages are unowned (i.e. "just DMA-safe memory pages"),
they won't consume any swap resources, as the mappings are wired, and
the pages aren't on the active or inactive queues.

Don't use pmap_kenter_pgs() for entering pager_map mappings. The pages
...
are still owned by the object which is paging, and so the test for a kernel
object in uvm_unmap_remove() will cause pmap_remove() to be used instead
of pmap_kremove().
This was a MAJOR source of pmap_remove() vs pmap_kremove() inconsistency
(which caused the busted kernel pmap statistics, and a cause of much
locking hair on MP systems).
