in bufs_info sysctl handler. dev->dma and dev->dma_lock existence are
protected by DRM_LOCK(). Fixes panic on sysctl hw.dri when the device is
uninitialied (when you aren't in X).
- Add a DDB function to dump the contents of an ithread and optionally
details about each handler in that ithread. This function can be used
by MD code to implement DDB commands that display information about
interrupt sources and their registered handlers.
the ACPI timer and we shouldn't do that if ACPI is already around to do
that for us.
- Set a description and tweak the order of checks in the probe function
to more closely match other PCI drivers.
This should probably be moved to sys/dev/piix/piix.c at some point and
turned on for all i386 kernels rather than just SMP ones.
(aka RFC2292bis). Though I believe this commit doesn't break
backward compatibility againt existing binaries, it breaks
backward compatibility of API.
Now, the applications which use Advanced Sockets API such as
telnet, ping6, mld6query and traceroute6 use RFC3542 API.

stdin and stdout instead of relaying the data. Now it is possible
to say:
nghook -e path: hook /usr/local/bin/foo arg1 arg2
and foo will have the hook to path: at file descriptors 0 and 1.
Add an option to specify control messages to be send to the node before
either executing the program or entering the data relay loop.

- Modify vm_pager_put_pages() and vm_pager_page_unswapped() to expect the
vm object to be locked on entry. (All of the pager routines now expect
this.)
that at most 20% of sockets can be in time_wait at one time, ensuring
that time_wait sockets do not starve real connections from inpcb
structures.
No implementation change is needed, jlemon already implemented a nice
LRU-ish algorithm for tcp_tw structure recycling.
This should reduce the need for sysadmins to lower the default msl on
busy servers.
overlapping TR/TC entries (which results in a machine check). Note
that we don't look at the size of the memory descriptor, because
it doesn't guarantee non-overlap.
With this change, a UP kernel could boot on a Intel Tiger4 machine
with the following options:
options LOG2_ID_PAGE_SIZE=26 # 64M
options LOG2_PAGE_SIZE=14 # 16K

setting. Make va_copy be an alias if __ISO_C_VISIBLE >= 1999.
Why? more than a few ports have an autoconf that looks for __va_copy
because it is available on glibc. It is critical that we use it if
at all possible on amd64. It generally isn't a problem for i386 and its
ilk because autoconf driven code tends to fall back to an assignment.
locking, and the apparently unnecessary locking for -stable has been removed.
This may fix issues with missed interrupts since April, which manifested
themselves as slowdowns or hangs in radeon, in particular. Many cleanups also
took place. In the shared code, there are improvements to r128 driver
stability.

o cleanup data structures on module unload when no application has
been started (i.e. kldload, kldunload w/o mrtd)
o remove extraneous unlocks immediately prior to destroying them
