fde8140fde Erm, don't forget to store the mbuf in the dmamap in bus_dmamap_load_mbuf_sg(), 
so that bus_dmamap_sync() knows what to invalidate. This makes em(4) work again.
While I'm there, remove the unused "first" variable.

1f70d62298 Modify pmap_enter_quick() so that it expects the page queues to be locked 
on entry and it assumes the responsibility for releasing the page queues
lock if it must sleep.

Remove a bogus comment from pmap_enter_quick().

Using the first change, modify vm_map_pmap_enter() so that the page queues
lock is acquired and released once, rather than each time that a page
is mapped.

e1e6b9d3c6 - The IQ80321 has a jumper which changes the PCI device id from 4 to 8 for the 
GigE controller, so handle this.
- Use the outbound window 0 if the PCI mem requested is in its range, instead
of inconditionally use the outbound window 1.
This should be enough to get FreeBSD/arm to work on the IQ80321 board as well.

85f5b24573 In the common case, pmap_enter_quick() completes without sleeping. 
In such cases, the busying of the page and the unlocking of the
containing object by vm_map_pmap_enter() and vm_fault_prefault() is
unnecessary overhead.  To eliminate this overhead, this change
modifies pmap_enter_quick() so that it expects the object to be locked
on entry and it assumes the responsibility for busying the page and
unlocking the object if it must sleep.  Note: alpha, amd64, i386 and
ia64 are the only implementations optimized by this change; arm,
powerpc, and sparc64 still conservatively busy the page and unlock the
object within every pmap_enter_quick() call.

Additionally, this change is the first case where we synchronize
access to the page's PG_BUSY flag and busy field using the containing
object's lock rather than the global page queues lock.  (Modifications
to the page's PG_BUSY flag and busy field have asserted both locks for
several weeks, enabling an incremental transition.)
