3MB of physical memory for heap instead of range between 1MB and 4MB.
This makes this feature working with PAE and amd64 kernels, which are
loaded at 2MB. Teach i386_copyin() to avoid using range allocated by
heap in such case, so that it won't trash heap in the low memory
conditions.
This should make loading bzip2-compressed kernels/modules/mfs images
generally useable, so that re@ team is welcome to evaluate merits
of using this feature in the installation CDs.

and including both in this file had nasty side effects on the
ordering of syslogd, as well as producing an error when running
rcorder. Remove the more bogus of the two options, which restores
proper ordering and removes the error.
There is an open question as to whether scripts with the nostart
KEYWORD should even have REQUIRE/BEFORE lines, and indeed, whether
they should be in /etc/rc.d at all, but that's for another time.
the addition of pci_find_extcap().
- Change the drm drivers to attach to vgapci. This is #ifdef'd so the
code can be shared across branches.
- Use pci_find_extcap() to look for AGP and PCIE capabilities in drm.
- GC all the drmsub stuff for i810/i830/i915. The agp and drm devices are
now both children of vgapci.
as a bus so that other drivers such as drm(4), acpi_video(4), and agp(4)
can attach to it thus allowing multiple drivers for the same device. It
also removes the need for the drmsub hack for the i8[13]0/i915 drm and agp
drivers.

attach to the hostb driver instead. This means that agp can now be loaded
at runtime (in theory at least). Also, the drivers no longer have to
explicity call device_verbose() to cancel out any earlier calls to
device_quiet() by the hostb(4) driver (this shows a limitation in new-bus,
drivers really shouldn't be doing device_quiet() until they know they are
going to drive that device, i.e. in attach).
duplicated anyways) and into a single MI driver. Extend the driver a bit
to implement the bus and PCI kobj interfaces such that other drivers can
attach to it and transparently act as if their parent device is the PCI
bus (for the most part).
ELF trampoline build its own target, "trampoline".
It makes it possible to construct a bootable gzipped kernel without having
to build in the same process.
by default, so add a new knob that is on by default, and check that
knob in start_precmd so that it can run even if cleaning /tmp is
not enabled. This has the advantage of not violating POLA, while
still allowing the user to disable this behavior if they wish (for
example on a server that will never run X).
drivers already map sections into KVA as needed anyway. Note that this
will probably break the nvidia driver, but I will coordinate to get that
fixed.

to search for a specific extended capability. If the specified capability
is found for the given device, then the function returns success and
optionally returns the offset of that capability. If the capability is
not found, the function returns an error.
holiday is now celebrated on December 1st. From the PR:
December 1 was adopted as National Day in 1990, being the day of
celebration of the Great Assembly of Alba Iulia which voted for the
union of Transylvania with Romania and which symbolise the union of all
Romanians within a single state and the achievement of the unity of
Romanian national state. [1]

distributed non-large args, this saves about 14 of 134 cycles for
Athlon64s and about 5 of 199 cycles for AthlonXPs.
Moved the check for x == 0 inside the check for subnormals. With
gcc-3.4 on uniformly distributed non-large args, this saves another
5 cycles on Athlon64s and loses 1 cycle on AthlonXPs.
Use INSERT_WORDS() and not SET_HIGH_WORD() when converting the first
approximation from bits to double. With gcc-3.4 on uniformly distributed
non-large args, this saves another 4 cycles on both Athlon64s and and
AthlonXPs.
Accessing doubles as 2 words may be an optimization on old CPUs, but on
current CPUs it tends to cause extra operations and pipeline stalls,
especially for writes, even when only 1 of the words needs to be accessed.
Removed an unused variable.
The purpose of this change is consistency (not performance improvement:)),
as it was hard to tell if fdrop() is MPSAFE or not when I saw it sometimes
under the Giant and sometimes without it.
