1) After setting an input or output channel to pause, watch for DCH (DMA
halted) to be set before resetting the registers. The manual says this is
required. This *may* fix random auich lockups.
2) Add auich_{trigger,intr,halt}_pipe(), which can operate on any of the
input and output channels. This reduces code duplication quite a bit.
While I'm at it, fill in the mic interrupt handling.
3) The mic in interrupt is MINT, not MIINT. (The latter is modem input.)
- Add xen devices to MAKEDEV
- Add Xen kernels to list of kernel to build
- Add INSTALL_XENU to the install kernels
- introduce the xbd disk devices to sysinst.
This will add 3 kernels to the i386 release:
XEN0 for use as a Xen domain0 kernel
XENU for use on a non-privileged domain
INSTALL_XENU to install NetBSD on a non-privileged domain virtual disk.
* Only futz with the done list in the soft interrupt handler. In the hard
interrupt handler, do nothing except mask WDH and queue the soft interrupt.
This simplifies a bunch of code, removes two O(n^2) queue manipulations,
and gets rid of some really sketchy stuff around the queue head access.
* Use the auto-masking code at the end of the interrupt handler for both WDH
and RHSC interrupts. Again, this reduces the code a little, and avoids
multiple writebacks to the chip registers.
* Improve some comments and (error) messages.
* Use EXIT_FAILURE and EXIT_SUCCESS.
* Add function `maybe_syslog' (only log when -l is enabled).

in connected state. Avoid a panic when the interface is configured
before being in connected state (e.g. when configured automatically by xend
when a domain is created).
Remove the padding bits from blkif_extent_t, so that the message size doesn't
change. You'll need xentools20-2.0.3nb1 if you upgrade your kernel
(the old tools didn't zero out the padding bits, and a new kernel will
interpret them as part of the device number).
previously-allocated pages may not have been loaned to the remote domain
yet. Let the called deal with this.
- clean up the TX and RX loops to use less MASK_NETIF_xX_IDX() calls
- When we're done with the queued TX requests, try again in case some new
ones are available
- avoid leaking a xmit page if we queued NB_XMIT_PAGES_BATCH requests.
- remove dead code.
