It turns out that le16_to_cpup() and le32_to_cpup() aren't always safe
to call with pointers into packed structures, since those are inlined
functions and GCC may lose the "packed" attribute. So those references
can become unaligned kernel accesses, which are evil on some hardware.
This patch updates uses of those routines in the gadget stack. The
references into packed structures can just use leXX_to_cpu(*x), which
in most cases is more natural. Some other uses in RNDIS, mostly in
debug code, were wrong in the first place; those use get_unaligned().

  [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.

b2c2-flexcop-pci module, that is dependent on CONFIG_PCI, fixing the bug
as reported by Geert Uytterhoeven <geert@linux-m68k.org>:
drivers/media/dvb/b2c2/flexcop-dma.c uses the PCI DMA API, but
DVB_B2C2_FLEXCOP doesn't depend on PCI, causing the following problem on
PCI-less systems:

| linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent'

DVB_B2C2_FLEXCOP_PCI and DVB_B2C2_FLEXCOP_USB.

Sliced VBI transfers use PIO instead of DMA. This was done inside the
interrupt handler, but since PIO accesses are very slow this meant that
a lot of time was spent inside the interrupt handler. All PIO copies are
now moved to a workqueue. This should fix various issues with missing time

If the SAA7111 device is powered down, and requires re-initialisation when
the V4L device is opened (as on the NetWinder), the SAA7111 driver gets
completely confused about the current settings.
The problem is centred around the way the driver keeps _two_ cached copies
of the current settings - one of the struct video_picture settings, and one
of the registers.
When the decoder is re-initailised, the cached register settings are
overwritten, as are the values in the hardware registers. However, the
cached video_picture settings are not.
Resolve this by removing the useless and buggy second level of caching for
video_picture. Instead, provide a function which updates register values
if and only if the value we are going to write to the register has changed.

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.
