2ae0fcd220 Do not use the IO-mapping to issue the reset on the 82546 on arm. For some 
reason, it results in corrupted descriptors.

332d16a165 Add the possibility to specify the kernel virtual address and the kernel

6052fa47a9 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.

7c320e5bfb Add new functions to know which irqs are pending, and to mask and unmask 
interrupts, as these are CPU specific.
If the interrupt handler is not marked as INTR_FAST, don't unmask the
interrupt until it as been serviced.

1e82631893 Rename macroes, as we don't need to mess with alignment faults. 
Call ast() if TDF_NEEDRESCHED is set too, not just TDF_ASTPENDING.

8e90166a08 Implement pmap_growkernel() and pmap_extract_and_hold(). 
Remove the cache state logic : right now, it provides more problems than it
helps.
Add helper functions for mapping devices while bootstrapping.
Reorganize the code a bit, and remove dead code.

f186a29521 Backout the hack to install mtree, newsyslog, and touch in the cloned 
root in the previous commit.  We'll fix /etc/rc.d/var directly (someday).

02910eee10 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.

058cab4b41 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.

e6c8092ba0 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).
