The function vfs_write_suspend stops all new write operations to a file

to complete, then sync's the file system to disk and returns. The

complete.

This adds a device (atabus) between IDE controllers and wd or atapibus, to
have each ATA channel show up in the device tree. Later there will be atabus
devices in /dev, so that we can do IOCTL on them.
Each atabus has its own kernel thread, to handle operations that needs polling,
e.g. reset and others.
Device probing on each bus it defered to the atabus thread creation.
This allows to do the reset and basic device probes in parallel, which reduce
boot time on systems with several pciide controllers.
When probing a nonexistent slave, we may timeout waiting for an interrupt.
In __wdccommand_start(), for polled data in commands, abort quickly if
status still read 0 after 400ns (for a nonexistant slave, the
command will either be aborted, or the status register will report 0; for
a real device we should have BSY, DRQ or ERR).
Thanks to Alexander Yurchenko for reporting the problem and testing the
fix.

* Lower the buffer size to one page.

* auich_calibrate() assumes that the AC97 part is in its reset state. To
ensure this, call audio_attach_mi() after auich_calibrate().
* Explicitly support 12000Hz and 24000Hz. (Why is there a discrete list at
all?)
* Fix an obvious recording bug -- we were acking the wrong interrupt.
* Ensure that we don't get an interrupt during the AC97 speed probe by clearing
the "interrupt on completion" bit in the DMA setup.
* Separate the code to set the default parameters into a new function,
audio_set_defaults(). Make it use audiosetinfo(), which properly initializes
the block size and whatnot. Use this in both audioattach() and the
/dev/audio case of audio_open().
* Do not force a reinitialization when /dev/sound is opened.
* Do all of the block size sanity checks in auto_init_ringbuffer(), not in
both audio_calc_blksize() and audiosetinfo().
* Fix a bug in audiosetinfo() that caused the block size to not be recalculated
immediately if we set it to 0.
* For AUDIO_GET[IO]OFFS, modify the deltablks calculation so that it gives us
the number of block boundaries crossed.

to pci_attach_args. The latter is allocated on the stack during auto-

It's amazing how the old code worked for so long. I guess pci_attach_args
is allocated deep in pid#0's kernel stack on most platforms.

- if_bcereg.h should only have register definitions, so declarations
of softc structure etc. should be in if_bce.c.
- The types of DMA descriptors should be u_int32_t, not unsigned long.
- netinet headers are not required here.
- Values passed via bce_tx_ring should also be byte-swapped.
- byte-swapping is not needed for bus_space access.
from me:
- KNF
- mark all magic numbers with /* MAGIC */ so they can be identified at
some point. there are 33 in total though many appear to be the same
value, or related (eg, the 6 emac points.)
leaves these issues:
- RX pre-packet headers need to be byte-swapped or not?
- PAGE_SIZE bytes are allocated for both TX and RX DMA ring descriptors,
but they should be 1024 (== sizeof(struct bce_dma_slot) * N[TR]XDESC).
- the mcast filter.
it should be there, but in practice, on some systems an ugly race condition
rears its head: SCSI commands are issued before the FC thread ever runs, and
fail from then on forever. Yuck.
The driver backend is capable of supporting also ISA cards (no DMA)
and primary rate (PRI) cards in addition to the basic rate ones,
but I don't any to test on right now, so we don't support those
currently.

1) Don't wait for DRQ on an IDENTIFY command -- if it's not set when we see
BSY clear, abort the command and ignore the drive. (Do this by testing
for DRQ in the read/write cases in __wdccommand_intr().)
2) Don't wait for DRQ to deassert when we finish an IDENTIFY (or any other
non-block command that reads data) -- we don't do this for block I/O, and
empirically it doesn't clear on my CF cards at all, causing a pointless 1s
delay.
3) Add comments to some of the delay()s, and add missing ones in wdcreset()
and the WDCC_RECAL in the so-called "pre-ATA" probe.
4) Slightly simplify the reset sequence -- we were doing an extra I/O.
5) Modify the register writability test to make sure that registers are not
overlapped -- this can happen in some weird cases with a missing device 1.
6) Check the error register value after the reset -- if it's not 01h or 81h,
as appropriate (see ATA spec), punt.
Tested with a number of ATA-only, ATAPI-only, mixed ATA-ATAPI, CF, and IDE
disk configurations.
Also remove the SINGLE_DRIVE nonsense again.

device 1 isn't present. Pointed out by Quentin Garnier.
So the only way to know if device 1 is there or not is to send a command, which
is done later.
Detecting the second device here isn't important and won't speed up the probe.
We just need to know if there is at last one device on the bus.
