Now that free_pv_entry() accesses the pmap, call free_pv_entry() in
pmap_remove_all() before rather than after the pmap is unlocked. At
present, the page queues lock provides sufficient sychronization. In the
future, the page queues lock may not always be held when free_pv_entry() is
called.
Add regression tests of the emulation of the long branch conditional form.
These tests can obviously only be run on Merced processors, as they don't
implement the long branch.
Remove sysctl_vm_zone() and vm.zone sysctl from 7.x. As of 6.x,
libmemstat(3) is used by vmstat (and friends) to produce more accurate
and more detailed statistics information in a machine-readable way,
and vmstat continues to provide the same text-based front-end.

Make three simplifications to pmap_ts_referenced():
Eliminate an initialized but otherwise unused variable.
Eliminate an unnecessary test.
Exit the loop in a shorter way.
Some rearrangement of headers to minimize diffs with outside of
FreeBSD repository and to clean up the license header so as to
not pollute the license with file function.
Zero all mailbox structures prior to use (just in case). Change
the outgoing mailbox count for INIT_FIRMWARE to be correct.
Fix a compile time problem on amd64. I'm not sure if the fix is correct
from a semantic point of view, but I notified the author of the driver
for confirmation. So far it at least fixes the build and should only
lead to not identifying or wrongly identifying a soundcard in the worst
case.

tighten invariant on loops used to parse ie's; this ensures we never
touch data outside the packet (previously we might touch 1 byte); it
also has the happy side effect of working around broken orinoco/agere
firmware that sends malformed association response frames
If we're in mpt_wait_req and the command times out,
mark it as timed out. Don't try and free the config
request for read_cfg_header that times out because
it's still active. Put in code for the config reply
handler that will then free up timed out requests.
Fix the FC_PRIMITIVE_SEND completion to not try
and free a command twice. Dunno how this possibly
could have been working for awhile.
If the card has target mode enabled, and we hang
out ELS buffers but *don't* hang out commands,
we hang folks on the SAN because the LSI-Logic
f/w apparently sends back BUSY or QFULL or some
darn thing.
If we add command buffers, we have to respond to
them sensibly even if we don't have any upstream
listeners (scsi_targ or scsi_targ_bh), so put in
some local command reponse stuff.
Add snd_emu10kx driver for Creative SoundBlaster Live! and Audigy series
sound cards with optional pseudo-multichannel playback.
It's based on snd_emu10k1 sound driver. Single channel version is available
from audio/emu10kx port since some time.
The two new ALSA header files (GPLed), which contain Audigy 2 ("p16v") and
Audigy 2 Value ("p17v") specific interfaces, are latest versions from ALSA
Mercurial repository.
- Update ALSA emu10k1.h (it was imported as emu10k1-alsa.h) header file to
latest version from Mercurial repository. It brings definition of some
additional Audigy 2 / Audigy 2 Value registers.
- Use new #defines from ALSA emu10k1.h
- Remove unused include files:
+ emu10k1-ac97.h was imported from ALSA and never used,
+ emu10k1.h was imported from Creative Linux emu10k1 driver, but only
AUDIGY_CODEBASE was used from it.

Add FreeBSD version information to the menu title so it's possible to
see which release you are installing (really which FreeBSD version the
installer is running, but that shouldn't matter in all normal cases).
Make pc_freemask an array of uint32_t, rather than uint64_t. (I believe
that the use of the latter is simply an oversight in porting the new pv
entry code from amd64.)
Enable debug.mpsafevfs by default on arm. Since every architecture except
powerpc has debug.mpsafevfs enabled by default, it is shorter to enumerate
the architectures on which debug.mpsafevfs is off.
Allow iic bridges to support a generalized transfer, rather than
forcing all transfers to do the start read/write stop by hand. Some
smart bridges prefer this sort of operation, and this allows us to
support their features more easily. When bridges don't support it, we
fall back to using the old-style opertaions. Expand the ioctl
interface to expose this function. Unlike the old-style interface,
this interface is thread safe, even on old bridges.
MFp4:
Introduce framework to configure the multiplexed pins on boot.
Since the USART supprots RS-485 multidrop mode, it allows the
TX pins to float. However, for RS-232 operations, we don't
want these pins to float. Instead, they should be pulled up
to avoid mismatches. Linux does something similar when it
configures the TX lines. This implies that we also allow the
RX lines to float rather than be in the state they are left in
by the boot loader. Since they are input pins, I think that
this is the right thing to do.
For the moment, make board configuration a compile time option. This
saves space in the final kernel, but at the expense of flexibility to
boot the same kernel accross a family of boards.
Be sure to flush the cache after a partial read on timeout. Expand
comments about timeouts. Fix a style nit. Sometimes small messages
were getting corrupted.
o compat_group() and files_group() are more complicated than I thought
in rev. 1.34. Mainly I missed the fact that the buffer is used for two
purposes:
1) storing a group line from the group file;
2) __gr_parse_entry() parses the buffer and tries to put the group
members to the remaining part of the buffer and can fail if there
is no enough room for them.
Re-arrange the buffer size checks to account the latter case.
Define prototype for pru_close, which in the future will notify the
protocol of a socket close event distinct from a detach event, which
will (in a future commit) become aligned with pru_abort, which will
also be a notification of close prior to detach. Add prurequests event
for close, as well as patch up some existing missing ones.

Reduce the memory requirements for the tables by (1) using malloced strings
instead of maximum sized arrays embedded in the table structures and (2)
using pointers to constant oids instead of copying the oid into each
table structure. This also fixes indexing in the case when a string used
for indexing is longer than the maximum size allowed in the MIB.
Add MEMORY_BARRIER for the few scratch dma ops that were missing
them plus add a couple of hi 32 bit dma ops (we could probably
allow 64 bit scratch and request/response queue dma now).
Caching scheduling policy and priority in userland, a critical but baddly
written application is frequently changing thread priority for SCHED_OTHER
policy.
Create the diskless magic files in /etc during the install_etc() step
instead of setup_nanobsd(), because this gives customize tasks a chance
to fiddle the details.

Backout the feature which can change thread's scheduling option, I really
don't want to mix process and thread scheduling options together in these
functions, now the thread scheduling option is implemented in new thr
syscalls.
Add syscalls thr_setscheduler, thr_getscheduler, and thr_setschedparam,
these syscalls are designed to set thread's scheduling parameters and
policy, because each syscall contains a size parameter, it is possible
to support future scheduling option, e.g SCHED_SPORADIC, this option
needs other fields in structure sched_param, current they are not
avaiblable.
Honor db_pager_quit in 'show threadchain', 'show allchains', and
'show lockchain'. This is especially helpful for the first 2 as a
threadchain could get stuck in an infinite loop during a mutex deadlock.
Simplify the pager support in DDB. Allowing different db commands to
install custom pager functions didn't actually happen in practice (they
all just used the simple pager and passed in a local quit pointer). So,
just hardcode the simple pager as the only pager and make it set a global
db_pager_quit flag that db commands can check when the user hits 'q' (or a
suitable variant) at the pager prompt. Also, now that it's easy to do so,
enable paging by default for all ddb commands. Any command that wishes to
honor the quit flag can do so by checking db_pager_quit. Note that the
pager can also be effectively disabled by setting $lines to 0.
Other fixes:
- 'show idt' on i386 and pc98 now actually checks the quit flag and
terminates early.
- 'show intr' now actually checks the quit flag and terminates early.

Teach mount(8) about a 'late' keyword, which means the file system should
not be mounted unless the -l flag was specified.
Add an rc script, mountlate, which basically runs 'mount -a -l'. It runs
after DAEMON but before LOGIN.
This is useful for things like loopback mounts, because mountcritremote
runs before mountd / nfsd (since /usr might be a remote file system), so
an attempt to mount a loopback network file system in mountcritremote will
fail.
Also add a progress message to mountcritlocal, for the sake of symmetry
with similar messages in mountcritremote and mountlate.
