at 0 as designed. Its BSD adaptation tries to fight it by mapping 0 to
2147483647 after calculation, but this method not works since 2147483647
seed returns to 0 again on the next interation. Instead of after calculation
mapping, map 0 to another value _before_ calculation, so it never stucks.

initialize the context. This way, a failure to initialize the context is
not fatal unless we actually have work to do - because if we don't, we
return PAM_SUCCESS without even trying to initialize the context.
- Fix overwrite problem of freed buffers. It was rare but could happen
when fwohci_arcv() is called before fwohci_txd() is called for
the transcation.
- Drain AT queues and pend AR queues on SID receive rather than BUS reset to
make sure DMA actually stops.
- Do agent reset in sbp_timeout().
have some negative effect on interactivity but it yields great perf. gains.
This also brings the conditions under which ULE context switches inline
with SCHED_4BSD.
- Define some new kseq_* functions for manipulating the run queue.
- Add a new kseq member ksq_rslices and ksq_bload. rslices is the sum of
the slices of runnable kses. This will be used for push load balance
decisions. bload is the number of threads blocked waiting on IO.
likely not present under the simulator. If multiple partitions are
present on the virtual disk, then the 'a' partition would be the
most logical choice. Nowadays partitions are GPT based, which would
make the assumption of a disklabel even more questionable. Given
all the possible scenarios, assuming a raw "device" seems best.
- Use atomic subtract to update the global wired pages count. (See
also vm/vm_page.c revision 1.233.)
- Assert that the page queue lock is held in pmap_remove_entry().
- Implement TX power control with hints to code in Linux driver
by Douglas S. J. De Couto <decouto@lcs.mit.edu>
- Update ifmedia support to use ieee80211_rate2media and
ieee80211_media2rate. Note doesn't work with stock ifconfig
since there seems to be an issue with the setmedia code.
"ancontrol -t" works now, before it did nothing.
- Fix spelling error in header.
Rename functions bctv_* to bctv2_* and macros BCTV_* to BCTV2_* for
coexistance of BCTV2 and BCTV3.
Rename CARD_IO_GV to CARD_TO_BCTV2.
Add auto recognition of BCTV3/PCI.

saving and restoring ia32 specific registers when switching
context and ia32 support has not been compiled-in. The primary
reason for this change is that one of the ia32 registers (ar.fcr)
is wrongly marked as invalid by the simulator. Now that we avoid
using the register when possible, usability is improved. The
secundary reason is that it saves us 7 loads and stores.
Note that the PCB will continue to have room for these registers,
irrespective of the IA32 option. There are no benefits that make
it worthwhile.
