  [PATCH] ide: if the id fields looks screwy, disable DMA
  It's the safer choice. Originally due to a bug in itx821x, but a
  generally sound thing to do.
  Signed-off-by: Jens Axboe <axboe@suse.de>
However it worked by pure luck before Jens' fixes: bogus ide_dma_enable()
usage in it821x driver combined with loosy check in ide_dma_verbose() allowed
the hardware to operate in DMA mode. When these problems were fixed the DMA
support broke...
The source root for the regression turned out to be that the it821x.c code
was clearing too much of id->field_valid. The IDE core code was using the
original value of id->field_valid to do the tuning but later DMA got disabled
in ide_dma_verbose() because of the incorrect id->field_valid fixup. Fix it.
While at it:
* Do fixup() after probing the drives but before tuning them (which is also
OK w.r.t. ide_undecoded_slave() fixup). This change fixes device IDENTIFY
data to be consistent before/after the tuning and allows us to remove extra
re-tuning of drives from it821x_fixups().
* Fake MWDMA0 enabled/supported bits in IDENTIFY data if the device has
DMA capable bit set (this is just to tell the IDE core that DMA is
supported since it821x firmware takes care of DMA mode programming).
* Don't touch timing registers and don't program transfer modes on devices
et all when in RAID mode - depend solely on firmware to do the tuning
(as suggested by Alan Cox and done in libata pata_it821x driver).
Thanks for testing the patch goes out to Thomas Kuther.

Problem noticed by Joe Zbiciak, see
http://kerneltrap.org/node/8252
for details.
On CSB6 the driver is using BIOS settings and not programming DMA/PIO timings
itself. However the logic was completely broken and resulted in wrong timings
being silently allowed (instead of being corrected by the driver).
This bug would explain some data corruption/timeout issues with Serverworks
MegaIDE in RAID mode that Alan Cox has fixed recently with:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2074a106f52b6371885afbd714e929d60d0e3f64
For 2.6.23 we may be better off with completely switching the driver to always
programming timings (libata pata_serverworks.c driver is doing things this way
and there were no problems reported so far) but for 2.6.22 lets fix the bug
in the simplest and the least intrusive way.

The statistics block DMA on 5708 can be messed up occasionally on the
average of about once per hour. If the user is reading the counters
within one second after the corruption, the counters will be all
messed up. One second later, the counters will be ok again until the
next corruption occurs.
The workaround is to disable the periodic statistics DMA. Instead,
we manually trigger the DMA once a second in bnx2_timer(). This
manual trigger of the DMA avoids the problem.
As a consequence, we can only allow 0 or 1 second settings for
ethtool -C statistics block.

There's a bug in the driver that only initializes half of the context
memory on the 5708. Surprisingly, this works most of the time except
for some occasional netdev watchdogs when sending a lot of 64-byte
packets. The fix is to add the missing code to initialize the 2nd
halves of all context memory.

Several people have reported LITE-ON LTR-48246S detection failed
because SETXFER fails. It seems the device raises IRQ too early after
SETXFER. This is controller independent. The same problem has been
reported for different controllers.
So, now we have pata_via where the controller raises IRQ before it's
ready after SETXFER and a device which does similar thing. This patch
makes libata always execute SETXFER via polling. As this only happens
during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is
also moved from issue hot path to ata_dev_set_xfermode() - the only
place where SETXFER can be issued.
Note that ATA_TFLAG_POLLING applies only to drivers which implement
SFF TF interface and use libata HSM. More advanced controllers ignore
the flag. This doesn't matter for this fix as SFF TF controllers are
the problematic ones.

There is a race between input handler's release() and disconnect()
methods: when input handler disconnects it wakes up all regular
users and then process to walk user list to wake up async. users.
While disconnect() walks the list release() removes elements of
the same list causing oopses.
While this is not a substibute for proper locking we can reduce
odds of getting an oops if we wake up normal readers after walking
the list.

The compiler warning
drivers/atm/firestream.c: In function ‘top_off_fp’:
drivers/atm/firestream.c:1505: warning: cast to pointer from integer of different size
does indicate a bug, albeit a minor one. Fixed, by using a 32-bit
temporary prior to the call to bus_to_virt().
The larger bug is still present: the entire driver assumes that machine
pointers are 32-bit, as it stores pointers in 32-bit hardware registers.
This is obvious to anyone who knows the driver well, but for the casual
readers it is helpfully noted with FIXME.

The bug is caused by code that always set
(TG3_FLAG_USE_MI_INTERRUPT | TG3_FLAG_USE_LINKCHG_REG) on all Dell's
onboard devices. With these 2 flags set, the link status is polled
by tg3_timer() and will only work when the PHY is set up to interrupt
the MAC on link changes. This breaks 5906 because the 5906 PHY does
not support TG3_FLAG_USE_MI_INTERRUPT the same as other PHYs.
For correctness, only Dell's onboard 5701 needs these 2 flags to be
set. This change will fix the 5906 problem and will change other
Dell devices except 5700 and 5701 to use the more efficient
interrupt-driven link changes.
Update version to 3.77.

individually, which is rather bogus, as they can simply use

specifically).
There are also inb/outb definitions which are totally bogus (missing

try to use a 16-bit access to fake 8-bit access). Kill that nonsense off
