b0493a9984 Move device 'cs' into i386/pc98 specific NOTES. It is broken on ppc
because it uses i386 specific calls.  Maybe it could be added to
amd64, but I'm not so sure it would work there so I've not added it
there.

33181681c7 - Use PCIR_BAR() macro for the BAR for the aperture.
- Axe macros used for walking PCI capabilities list.  We now ask the PCI
  bus to find caps for us rather than doing it in the drm and agp drivers.

e9aa66d283 - Bump FreeBSD version for the hostb(4) and vgapci(4) drivers as well as
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.

8e8e46ccfc Add a vgapci(4) stub device driver for VGA PCI devices. This device serves
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

c626f1fe9a Change the various AGP drivers that attach to the Host-PCI bridge device to
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).

5b2119223e Move the hostb driver out of the i386 and amd64 PCI code (where it was
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).

aa5affaf3b Brooks pointed out a potential problem with disabling the X cleaning
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).

5bcf484019 Don't map the AGP aperture into contiguous KVA. The various graphics
drivers already map sections into KVA as needed anyway.  Note that this

7881e1ee07 Liberation Day is no longer celebrated in Romania; rather a national
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]

5776f433ab Extract the high and low words together. With gcc-3.4 on uniformly
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.

c505fe7a0f Reduce Giant scope a bit, as fdrop() is believed to be MPSAFE.
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.

f668cd5df7 If LOADER_BZIP2_SUPPORT is defined allocate heap in the 1MB-4MB range to
provide enough room for decompression (up to 2.5MB is necessary). This
should be safe to do since we load i386 kernels after 8MB mark now, so
that 16MB is the minimum amount of RAM necessary to even boot FreeBSD.

This makes bzip2-support  practically useable.

915dad0e92 Long-long time ago, when the trees were large and memory expensive amount of
memory directly available to loader(8) and friends was limited to 640K on i386.
Those times have passed long time ago and now loader(8) can directly access
up to 4GB of RAM at least theoretically. At the same time, there are several
places where it's assumed that malloc() will only allocate memory within
first megabyte.

Remove that assumption by allocating appropriate bounce buffers for BIOS
calls on stack where necessary.

This allows using memory above first megabyte for heap if necessary.
