6bce07ae73 It has been observed on the mailing lists that the different categories
of pages don't sum to anywhere near the total number of pages on amd64.
This is for the most part because uma_small_alloc() pages have never been
counted as wired pages, like their kmem_malloc() brethren.  They should
be.  This changes fixes that.

It is no longer necessary for the page queues lock to be held to free
pages allocated by uma_small_alloc().  I removed the acquisition and
release of the page queues lock from uma_small_free() on amd64 and ia64
weeks ago.  This patch updates the other architectures that have
uma_small_alloc() and uma_small_free().

6037400b5a It's probably time I learn C.
Fix a few while (!uart_getreg() & SR1_TNF) when
while (!(uart_getreg() & SR18TNF)) was really meant.
This driver should die anyway, it's awful, and uart_ns8250 should be fine
for the StrongArm 1110. I'll kill it later.

e8b7ad8c05 Add in all the USB devices and all the wireless goo. The KB9202 has

3f0fd37320 Make USB work on the KB9202{,A,B} boards. This has been in p4 for about
7 months.  You must have JP6 in the 1-2 position to supply power to the
USB devices, but I've used uftdi, uplcom and umass successfully.  If you
have it in 2-3, then nothing will show up.  Also, if you have the FQPA
packaging for the AT91RM9200 (like the KN9202 boards have), you will get
the following message

uhub0: device problem (IOERROR), disabling port 2

due to a hardware erratum.  It is safe to ignore as it is about pins that
aren't brought out on the FQPA package and aren't proeprly terminated either.
Alas, there's no register to read to tell the FQPA from the BGA versions.

6308183c5d MFppc:
revision 1.66
date: 2007/07/31 06:23:26;  author: marcel;  state: Exp;  lines: +2 -2
Fix backward compatibility of the "old" (i.e. FreeBSD6) lseek
syscall. It was broken when a new lseek syscall was introduced.
The problem is that we need to swap the 32-bit td_retval values
for the __syscall indirect syscall when the actual syscall has
a 32-bit return value. Hence, we need to exclude lseek(2). And
this means the "old" lseek(2) as well -- which we didn't.

Based on a patch from: grehan@

23f9626539 Bring in two bandaids to get the elf trampoline to work again, until I find
a proper solution.
- Add a dummy entry point which just calls the C entry points, and try to make
sure it's the first code in the binary.
- Copy a bit more than func_end to try to copy the whole load_kernel()
function. gcc4 puts code behind the func_end symbol.

6759608248 Rework the PCPU_* (MD) interface:
- Rename PCPU_LAZY_INC into PCPU_INC
- Add the PCPU_ADD interface which just does an add on the pcpu member
  given a specific value.

Note that for most architectures PCPU_INC and PCPU_ADD are not safe.
This is a point that needs some discussions/work in the next days.

3401f2c1df In some particular cases (like in pccard and pccbb), the real device
handler is wrapped in a couple of functions - a filter wrapper and an
ithread wrapper. In this case (and just in this case), the filter
wrapper could ask the system to schedule the ithread and mask the
interrupt source if the wrapped handler is composed of just an ithread
handler: modify the "old" interrupt code to make it support
this situation, while the "new" interrupt code is already ok.
