OpenBSD. This driver seems to give a small performance increase, and
should lead to better maintainability in the future.
The nForce Ethernet-specific hack in sys/i386/xbox/xbox.c is still
required, judging from dev/nfe/if_nfe.c. The condition it hacks will
almost certainly only occur on XBOX-es anyway, so it is best left there.

- the process group ID of the process which owns the connected tty
- some page fault stats
- time spend in kernel/userland
- priority/nice value
- starttime [1]
- memory/swap stats
- scheduling policy
Additionally add some new fields and correct some not filled out ones.
This brings us down to 15 dummy fields.
The fields marked with [1] are needed to get Oracle 10 running. The starttime
field is not completely right, since it displays the _same_ starttime for
_every_ process, but at least it is not 0 and Oracle accepts this.

memory space the 'buf' pointer of the union points to. This is then used
in linux_semctl() and svr4_sys_semctl() to eliminate use of the stackgap.
- Mark linux_ipc() and svr4_sys_semsys() MPSAFE.
notes:
- Adopted Solaris-compatible format for subject32_ex and subject64_ex
tokens, which previously did not correctly implement variable length
address storage.
- Prefer inttypes.h to stdint.h; enhance queue.h detection to test for
TAILQ_FOREACH_SAFE(), which is present in recent BSD queue.h's, but not
older ones. OpenBSM now builds on some FreeBSD 4.x version.
- New event types for extended attributes, ACLs, and scheduling.

- Expand the scope of Giant some in unmount(2) to protect the mp structure
(or rather, to handle concurrent unmount races) from going away.
umount(2) is now MPSAFE, as well as linux_umount() and linux_oldumount().
- nmount(2) and linux_mount() were already MPSAFE.
- For privileged processes safe two mutex operations.
We may want to consider if this is good idea to use SUSER_ALLOWJAIL here,
but for now I didn't wanted to change the original behaviour.

1. Make the caller responsible for performing pmap_install(). This reduces
the number of times that pmap_install() is performed by
pmap_enter_object() from twice per page to twice overall.
2. Don't block if pmap_find_pte() is unable to allocate a PTE. If it did
block, then it might wind up mapping a cache page. Specifically, if
pmap_enter_quick_locked() slept when called from pmap_enter_object(), the
page daemon could change an active or inactive page into a cache page just
before it was to be mapped.
3. Bail out of pmap_enter_quick_locked() if pv entries aren't plentiful.
In other words, don't force the allocation of a pv entry if they aren't
readily available.

pmap_copy() if the mapping is VM_INHERIT_SHARE. Suppose the mapping
is also wired. vmspace_fork() clears the wiring attributes in the vm
map entry but pmap_copy() copies the PG_W attribute in the PTE. I
don't think this is catastrophic. It blocks pmap_remove_pages() from
destroying the mapping and corrupts the pmap's wiring count.
This revision fixes the problem by changing pmap_copy() to clear the
PG_W attribute.

Finally fix the EEPROM reading code so that we can access the EEPROMs on all
devices. In order to access the EEPROM, we must select 'EEPROM programming'
mode, and then set the EEPROM chip select bit. Previously, we were setting
both bits simultaneously, which doesn't work: they must be set in the
right sequence.
Always obtain the station address from the EEPROM, now that EEPROM
reading works correctly.
Make the TX interrupt moderation code based on the internal timer
optional and turned off by default.
Make the re_diag() routine conditional and off by default. When it is
on, only use it for the original 8169, which was the only device that
that really needed it.
Modify interrupt handling to use a fast interrupt handler and fast
taskqeueue.
Correct the rgephy driver so that it only applies the DSP fixup for
PHY revs 0 and 1. Later chips are fixed and don't need the fixup.
Make the rgephy driver advertise both 1000_FD and 1000_HD bits in
autoneg mode. A couple of the devices don't autoneg correctly unless
configured this way.
all of the module event handlers are MP safe yet, so always acquire Giant
