ddebcb409b Eliminate one set of XBOX #ifdefs. The Xbox code just needs to set a
different TIMER_FREQ value than default.  Accomplish this via the
config file rather than via an #ifdef.

f56b5a43dc Strengthen the check for a PMBR:
o PMBR partitions count to the number of partitions on the disk, which
  means that if a PMBR entry is invalid we will not treat the MBR as a
  PMBR by virtue of it not describing any partitions.
  Previously the checks were inconsistent in that an invalid PMBR entry
  would be harmless when no other partitions exist (we would treat the
  MBR as a PMBR by virtue of it being empty), but it would be fatal when
  there is at least one other partition.
o The partition size of a PMBR partition is one less than the media size
  because the GPT starts at the second sector (LBA 1) and extends to
  the end of the media. For backward bug-compatibility we accept a size
  that's exactly the media size (FreeBSD bug).
  Also, when the partition size can not be represented in a 32-bit
  integral, the partition size in the MBR is to be set to 0xFFFFFFFF.
  Accept this as a valid size, even if the size can be represented.

c70759dcdd Add pc98 specific code to adjust the firmware geometry when it differs
from the actual geometry.  This enables support of disks larger than
~120GB on pc98 boxes.  They make great little network appliances.
I've been using these changes for the past year or so on my network
storage pc98 box :-).

ab649fd4d2 Most platforms map the actual drive geometry to the firmware's notion
of geometry.  However, some platforms have a more complicated mapping
of the firmware values to the actual values.  pc98 is the only
platform that currently does this.  This mapping is necessary for
large disks connected to pc98 boxes, as the firmware labels require do
special hacks to the actual geometry for interoperability.  We cannot
do this all in the geom layer because of initialization issues (geom
looks for an already initialized pc98 label, but we need the geometry
information prior to initialization, classic chicken and egg problem).
We pass the disk and the device_t to this function because the
geometry mapping depends on what kind of controller is used.

This hook allows platforms that want to override things to do so, and
has 0 overhead on all other platforms.  These patches have been in use
locally for a long time, and received good feedback from the pc98
community and sos@ at various times during their development.

5786be7cc7 Introduce a field to struct vm_page for storing flags that are
synchronized by the lock on the object containing the page.

Transition PG_WANTED and PG_SWAPINPROG to use the new field,
eliminating the need for holding the page queues lock when setting
or clearing these flags.  Rename PG_WANTED and PG_SWAPINPROG to
VPO_WANTED and VPO_SWAPINPROG, respectively.

Eliminate the assertion that the page queues lock is held in
vm_page_io_finish().

Eliminate the acquisition and release of the page queues lock
around calls to vm_page_io_finish() in kern_sendfile() and
vfs_unbusy_pages().

13c85d339d Add a bandaid to avoid a deadlock in a situation, when we are trying to suspend
a file system, but need to obtain a vnode. We may not be able to do it, because
all vnodes could be already in use and other processes cannot release them,
because they are waiting in "suspfs" state.

In such situation, we allow to allocate a vnode anyway.

This is a temporary fix - there is no backpressure to free vnodes allocated in
those circumstances.

9500ad1d7d Thomas Wintergerst reports that when this tsleep went away, certain
cards stopped working.  Specifically the AVM B1 PCMCIA Card no longer
detected.  Its CIS chain read back as all FF's.  Putting the delay
back solves those problems.  I've opted to put in a much shorter delay
because as far as I can tell, no delay is really needed here.  We'll
see how well this works in practice.

d1a5c5275c Fix a phase-ordering bug: check the mediasize and sectorsize after
we obtained access. It is possible that GPT gets to taste a disk
first, which means the disk has not been opened before and it will
not get opened until after we checked the mediasize and sectorsize.
However, since the mediasize and sectorsize are determined at open
and that happens when access is optained, checking the mediasize
and sectorsize before obtaining access may result in GPT rejecting
the disk.

49953e11d7 Rewrite ARM_USE_SMALL_ALLOC so that instead of the current behavior, it maps
whole the physical memory, cached, using 1MB section mappings. This reduces
the address space available for user processes a bit, but given the amount of
memory a typical arm machine has, it is not (yet) a big issue.
It then provides a uma_small_alloc() that works as it does for architectures
which have a direct mapping.

1565bf54af Lock the vnode around the call to VOP_GETATTR. Move the locked code
and vn_fullpath (that call malloc(..., M_WAITOK)) from under the
vm object lock, since sleep is not allowed while holding the mutex.

Being there, wrap VOP_GETATTR call with conditional Giant aquire.
Currently this is (almost) noop because pseudofs is Giant-locked.

is interaction between in-kernel sound buffer handling and hardware.
 With small buffer, there are times when both harwdare reads and

 think). I'm digging in channel.c and buffer.c to find a solution that
 allow use of large hardware buffers without sound lags - hardware can

This allows the hints to be used to work around broken BIOSes that don't
