TNT5004 IC. This involved a major rewrite of a number of things, as
this chip no longer supports the NAT7210 legacy mode but requires the
host to use the (more modern) FIFO mode.
In theory, this also ought to work on the older TNT4882C chip. I'll
probably add this as optional support (perhaps by a device.hints flag)
later on. By now, FIFO mode is *only* activates iff a TNT5004 chip
has been detected (where the old code didn't work at all), while
everything else is supposed to use the old code.

1. checking whether there's a link before initializing devices
on the bus. When there's no link any access onto the bus
will wedge the CPU.
2. synthesizing the class & subclass so that the host controller
appears as a standard PCI bridge, rather than a PowerPC CPU.
PCI Express, rather than a bit-field (boolean). Saving the capability
pointer this way makes access to capability-specific configuration
registers easy and efficient.
For our compiler the two constructs are completely equivalent, but
some compilers (including MSC and tcc) use the base type for alignment,
which in the cases touched here result in aligning the bitfields
to 32 bit instead of the 8 bit that is meant here.
Note that almost all other headers where small bitfields
are used have u_int8_t instead of u_int.

- Remove the BUS_HANDLE_MIN checking in the __BUS_DEBUG_ACCESS macro;
for UPA it should have fulfilled its purpose by now and Fireplane-
and JBus-based machines are way to messy in organization to implement
something equivalent.
- Fix a bunch of style(9) bugs.
- Const'ify the bus_stream_asi and bus_type_asi arrays.
- Replace hard-coded functions names missed in bus_machdep.c with __func__.
- Break some long lines.
* Fix a race in chunk_dealloc_dss().
* Check for allocation failure before zeroing memory in base_calloc().
Merge enhancements from a divergent version of jemalloc:
* Convert thread-specific caching from magazines to an algorithm that is
more tunable, and implement incremental GC.
* Add support for medium size classes, [4KiB..32KiB], 2KiB apart by
default.
* Add dirty page tracking for pages within active small/medium object
runs. This allows malloc to track precisely which pages are in active
use, which makes dirty page purging more effective.
* Base maximum dirty page count on proportion of active memory.
* Use optional zeroing in arena_chunk_alloc() to avoid needless zeroing
of chunks. This is useful in the context of DSS allocation, since a
long-lived application may commonly recycle chunks.
* Increase the default chunk size from 1MiB to 4MiB.
Remove feature:
* Remove the dynamic rebalancing code, since thread caching reduces its
utility.

passed to sysctl(8) across different systems where particular OIDs may not
exist, and still get as much information as possible from them.

for negative name cache entries in a manner analogous to

- Make sure the mode argument is either a character or a block device.
- Use S_IS*() instead of checking S_IF*-flags by hand.
- Don't use kern.devname when the argument is already NODEV.
- Always call snprintf with the proper amount of arguments corresponding
with the format.
- Perform some whitespace fixes. Tabs instead of 4 spaces, missing space
for return statement.
- Remove unneeded includes.

In 99% of the cases people just want to recreate device nodes they
removed from /dev. There is no reason to pass the additional "c 0 0"

Also slightly improve the manpage. Remove references to non-existent
device names and platforms.
interface's MTU to the if_bridge(4) interface. This fixes a
bug that MTU value of "addm <interface>" is used even when it
is invalid for the if_bridge(4) member:
# ifconfig bridge0 create
# ifconfig bridge0
bridge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
...
# ifconfig bridge0 addm lo0
ifconfig: BRDGADD lo0: Invalid argument
# ifconfig bridge0
bridge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 16384
...
- Do not ignore MTU value of an interface even when if_type == IFT_GIF.
This fixes MTU mismatch when an if_bridge(4) interface has a
gif(4) interface and no other interface as the member, and it
is directly used for L2 communication with EtherIP tunneling
enabled.
- Implement SIOCSIFMTU ioctl. Changing the MTU is allowed only
when all members have the same MTU value.
Also, change the existing -vi behavior to send the filenames to
stderr rather than stdout, as GNU cpio does.

This first commit brings 3 functions for enumerating, retrieving,
adding, removing and modifying EFI variables. The immediate use of these
include the insertion of a new boot option as part of the installation
process.
This library uses ioctl(2) requests implemented by io(4) to pass the
requests down through the kernel to EFI. These ioctl requests are only
implemented on ia64, so libefi is currently only enabled on ia64. The
interface is generic and io(4) on mad64/i386 can easily be taught to
handle these once EFI support has been added to the kernel there.
The basic idea is to use a the same virtual address as a window onto
distinct physical memory locations - one per processor. The physical
address that you access through this mapping depends on which cpu you
are currently executing on. We can now use the same virtual address
on any processor to access its per-cpu area.
The details are:
- The virtual address for 'struct pcpu *pcpup' is obtained by
stealing 2 pages worth of KVA in pmap_bootstrap().
- The mapping from the constant virtual address to a distinct
physical page is done in cpu_pcpu_init() through a wired TLB entry.
- A side-effect of this is that we reserve 2 pages worth of memory
for the pcpu but in reality it needs much less than that. The unused
memory is now used as the boot stack for the BSP and APs.
Remove SMP-specific bits from locore.S. The plan is to use a separate
mpboot.S for AP bootstrap.

lagg and vlan the vlan attach/detach event is not being
handed down to em, this caused some init code not to run,
and thus VLANs did not work. Ultimately having the event
get propagated would be nice, but for now the solution is
to have HWFILTER off by default, when this is the case
VLANs will work, ifconfig can be used to turn it on and
then get HW tag filtering.
programming I/F. New SoC designs have different device IDs, but
don't need special treatment. Consequently, we fail to probe and
attach for no other reason than not having added the device ID to
the code.
Bank on Freescale's sense of backward compatibility and assume
that if we find a host controller, we know how work with it.
This fixes detection of the PCI Express host controllers on
Freescale's QorIQ family of processors (P1, P2 and P4).
