a5a4c2b9b8 Import partial support for the IQ31244 eval board (i80321 CPU). IQ80321 might 
work out of the box too, but I have no hardware to test.
It works well enough to go multiuser. Network works, SATA does not, as I have
no drive to test.
Thanks to Intel for sending such a board.

f0ee02d552 Add new functions to know which irqs are pending, and to mask and unmask

If the interrupt handler is not marked as INTR_FAST, don't unmask the
interrupt until it as been serviced.

639630ead7 Implement pmap_growkernel() and pmap_extract_and_hold().

helps.
Add helper functions for mapping devices while bootstrapping.
Reorganize the code a bit, and remove dead code.

f2a11c9f2e Implement terminating the worker thread when the driver is about to 
be deregistered.

Not yet tested, since by now, GEOM doesn't want us to deregister.  PHK
wants to fix that RSN.

e7c39452fd Add locking notes on the members of rusage. Note that these notes reflect 
what is already present in the tree and apply to the rusage struct for
current process usage rather than child process usage.

08cbc59f16 Update locking notes on several fields to reflect locking already in the 
tree:
- td_standin is (k + a) as it is only touched by either curthread or when
  a thread is being created.
- td_upcall is (k + j)
- td_sticks is (k) rather than the earlier (j) note.
- td_uuticks and td_usticks are both (k).
- td_intrval is (j)
- Neither kg_nextupcall or kg_upquantum seem to be locked and that seems
  to be on purpose, so mark those as (n).
