bd6fb92679 Some more cleanups for vblank code on Intel.
The Intel 2d driver calls modeset before reinstalling the handler on
a vt switch.  This means that vblank status ends up getting cleared
after it has been setup.  Restore saved values for the pipestat registers
rather than just wiping them out.

87697759f9 Additional vblank cleanups.
Use the vbl_lock when maniputlating the refcount.  Eventually I want to
convert this to use our internal refcount code.  Continue to use atomic
ops for manipulating vblank count since we access it often just for
reading.

ce189363a0 Add a dying flag to prevent races at detach.
I tried re-ordering ether_ifdetach(), but this created a new race
where sometimes, when under heavy receive load (>1Mpps) and running
tcpdump, the machine would panic.  At panic, the ithread was still in
the original (not dead) if_input() path, and was accessing stale BPF
data structs.  By using a dying flag, I can close the interface prior
to if_detach() to be certain the interface cannot send packets up in
the middle of ether_ifdetach.

4713c64cd8 - Change this driver to do taskqueue(9) based TX and interrupt
handling in order to reduce interrupt overhead which results in
  better performance.
- Call ether_ifdetach(9) before stopping the controller and the
  callouts detach in order to prevent active BPF listeners to clear
  promiscuous mode which may lead to the tick callout being restarted
  which will trigger a panic once it's actually gone.
- Add explicit IFF_DRV_RUNNING checking in order to prevent extra
  link up/down events when using dhclient(8).
- Use the correct macro for deciding whether 2/3 of the available TX
  descriptors are used.
- Wrap the RX fault printing in #ifdef CAS_DEBUG in order to not
  unnecessarily frighten users and as debugging was the actual
  intention. Real errors caused by these faults still will be
  accumulated as input errors. It might be a good idea to later on
  add driver specific counters for the faults though.

8c4a62bd5b With the fdc control device disappearing some 5 years ago, it is no
longer useful for the FD_STYPE and FD_SOPTS ioctls to insist on being
issued on a writable file descriptor.  Otherwise, there's no longer a
chance to set the drive type or options when a read-only medium is
present in the drive, as there is no way to obtain a writable fd then.

6aa8875fe3 Revert the part of r194763 which added a dying flag and instead
call ether_ifdetach(9) before stopping the controller and the
callouts. The consensus is that the latter is now safe to do and
should also solve the problem of active BPF listeners clearing
promiscuous mode can result in the tick callout being restarted
which in turn will trigger a panic once it's actually gone.

fa686c638e Implement global and per-uid accounting of the anonymous memory. Add
rlimit RLIMIT_SWAP that limits the amount of swap that may be reserved
for the uid.

The accounting information (charge) is associated with either map entry,
or vm object backing the entry, assuming the object is the first one
in the shadow chain and entry does not require COW. Charge is moved
from entry to object on allocation of the object, e.g. during the mmap,
assuming the object is allocated, or on the first page fault on the
entry. It moves back to the entry on forks due to COW setup.

The per-entry granularity of accounting makes the charge process fair
for processes that change uid during lifetime, and decrements charge
for proper uid when region is unmapped.

The interface of vm_pager_allocate(9) is extended by adding struct ucred *,
that is used to charge appropriate uid when allocation if performed by
kernel, e.g. md(4).

Several syscalls, among them is fork(2), may now return ENOMEM when
global or per-uid limits are enforced.

224c243ab7 - Initialize the ifnet structure, especially if_dname, before probing
the PHYs as some PHY drivers use it (but probably shouldn't). How
  gem(4) has worked with brgphy(4) on powerpc without this so far is
  unclear to me.
- Introduce a dying flag which is set during detach and checked in
  gem_ioctl() in order to prevent active BPF listeners to clear
  promiscuous mode which may lead to the tick callout being restarted
  which will trigger a panic once it's actually gone.
- In gem_stop() reset rather than just disable the transmitter and
  receiver in order to ensure we're not unloading DMA maps still in
  use by the hardware. [1]
- The blanking time is specified in PCI clocks so we should use twice
  the value when operating at 66MHz.
- Spell some 2 as ETHER_ALIGN and a 19 as GEM_STATUS_TX_COMPLETION_SHFT
  to make the actual intentions clear.
- As we don't unload the peak attempts counter ignore its overflow
  interrupts.
- Remove a stale setting of a variable to GEM_TD_INTERRUPT_ME which
  isn't used afterwards.
- For optimum performance increment the TX kick register in multiples
  of 4 if possible as suggested by the documentation.
- Partially revert r164931; drivers should only clear the watchdog
  timer if all outstanding TX descriptors are done.
- Fix some debugging strings.
- Add a missing BUS_DMASYNC_POSTWRITE in gem_rint().
- As the error paths in the interrupt handler are generally unlikely
  predict them as false.
- Add support for the SBus version of the GEM controller. [2]
- Add some lock assertions.
- Improve some comments.
- Fix some more or less cosmetic issues in the code of the PCI front-end.
- Change some softc members to be unsigned where more appropriate and
  remove unused ones.

bc389932fa Update mxge firmware from 1.4.39 to 1.4.43. Changes include:
- Support for 10G-PCIE*-8B*-C (dual-port CX4)  NICs
- For dual-port NICs, f/w failover is now a few microsecs
    instead of a few millisecs.
-  On failover, f/w sends RARP broadcast to make the change
   immediately known to the network
- Fixed a bug observed on IBM X3 architecture where
   some spurious ecrc errors would be reported when OS enabled
   ecrc support.
