95e9f935c7 Add support for the U4 PCI-Express bridge chipset used in late-generation
Powermac G5 systems. MSI and several other things are not presently
supported.

The U3/U4 internal device support portions of this change were contributed
by Andreas Tobler.

0e169b2cc7 Allow to configure UMA usage for ZIO data via loader and turn it on by
default for amd64. On i386 I saw performance degradation when UMA was used,
but for amd64 it should help.

eb30e42c89 Add task structure to zio and use it instead of allocating one.
This eliminates the only place where we can sleep when calling zio_interrupt().
As a side-effect this can actually improve performance a little as we
allocate one less thing for every I/O.

4f54652124 The whole point of having dedicated worker thread for each leaf VDEV was to
avoid calling zio_interrupt() from geom_up thread context. It turns out that
when provider is forcibly removed from the system and we kill worker thread
there can still be some ZIOs pending. To complete pending ZIOs when there is
no worker thread anymore we still have to call zio_interrupt() from geom_up
context. To avoid this race just remove use of worker threads altogether.
This should be more or less fine, because I also thought that zio_interrupt()
does more work, but it only makes small UMA allocation with M_WAITOK.
It also saves one context switch per I/O request.

612952a975 Change the commented msgs examples in profile/csh.login from -f to -q.
Starting something that wants input on login seems strange and can be
dangerous. In some configurations, causing output can be bad, but it is not
as dangerous.

I do not expect this msgs invocation to be uncommented often.

32096493f0 Apply a patch that has been lingering in my inbox for far too long:
On a soekris Net5501, if you do a watchdog -t 16, followed by a watchdog
-t 0 to disable the watchdog, and then after some time (16s) re-enable
the watchdog the box reboots immediatly. This prevents also to stop and
restart watchdogd(8).

This is because when you stop the watchdog, the timer is not stoped,
only the hard reset is disabled. So when the timer has elapsed, the C2
event of the timer is set.

But when the hard reset is re-enabled, the event is not cleared and the
box reboots.

The attached patch stops and resets the counter when the watchdog is
disabled and do not disable the hard reset of the timer (if the timer
has elapsed it's too late).

c9d1ca826b Fix an issue with the dynamic pcpu/vnet data allocators.
We cannot expect that modspace is the last entry in the linker
set and thus that modspace + possible extra space up to PAGE_SIZE
would be contiguous.  For the moment do not support more than
*_MODMIN space and ignore the extra space (*).

(*) We know how to get it back but it'll need testing.

f545ac862c - Enable DMA write parity error interrupts on Schizo with a working
implementation.
- Revert the Sun Fire V890 WAR of r205254. Instead let schizo_pci_bus()
  only panic in case of fatal errors as the interrupt triggered by the
  error the firmware of these and also Sun Fire 280R with version 7
  Schizo caused may happen as late as using the HBA and not only prior
  to touching the PCI bus (in the former case the actual error still is
  fatal but we clear it before touching the PCI bus).
  While at it count and export non-fatal error interrupts via sysctl(9).
- Remove unnecessary locking from schizo_ue().

518f6e2bd2 If controller received bad frames make sure to update newly added
RFA. Also drop frames that have either CRC error or alignment
error. Normally bad frames are not received at all. But controllers
running in promiscuous mode will receive bad frames. 82557 will
also receive bad frames to receive VLAN oversized frames.

While I'm here mark RNR condition if driver happen to see RNR in
RFA status and restart RU to receive frames again. Because driver
checks all received frames in RX loop, RNR condition could be set
in the middle of RX processing. Just relying on RNR interrupt was
not enough.

This change fixes "Memory modified after free" issue when fxp(4)
is running as a member of if_bridge(4).
