The sysfs adsl_status attribute ignores (aside from returning -EIO to the
user) any error sending a START/STOP command to the device and there is at
least one firmware which never sends a response but appears to work
regardless. Therefore atm_start should also continue if an error is received
so that such firmware is usable.
The official Conexant driver doesn't expect a reply either but this is for
another device (E2 router) and a commonly used firmware does respond.
Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing
ever checks for either of these values.

Since usbatm doesn't set the usb_interface driver data until after calling
bind and heavy_init, it would be NULL when the sysfs attributes are read.
Reading the MAC address from atm_dev before atm_dev exists would have been
be possible too.
Calling create_device_file in atm_start will avoid this problem, and the
data is useless until the first status poll runs. However, it must be
ready before a status poll does a printk on line status change otherwise
userspace could react before the files exist.
For completeness I've moved remove_device_file to atm_stop so it's not
called in unbind when it's not needed. There's no point starting ADSL if
atm_start could still fail either.

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().

IPv4 options are not very well aligned within the packet and the
format of a CIPSO option is even worse. The result is that the CIPSO
engine in the kernel does a few unaligned accesses when parsing and
validating incoming packets with CIPSO options attached which generate
error messages on certain alignment sensitive platforms. This patch
fixes this by marking these unaligned accesses with the
get_unaliagned() macro.

operate on sockets and convert the callers. Not only does this make
the code smaller and more consistent but it pushes the locking burden
up to the caller which can be more intelligent about the locks. Also,

This patch makes CIFS honour a process' umask like other filesystems.
Of course the server is still free to munge the permissions if it wants
to; but the client will send the "right" permissions to begin with.
A few caveats:
1) It only applies to filesystems that have CAP_UNIX (aka support unix
extensions)
2) It applies the correct mode to the follow up CIFSSMBUnixSetPerms()
after remote creation
When mode to CIFS/NTFS ACL mapping is complete we can do the
same thing for that case for servers which do not
support the Unix Extensions.

  [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.

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.

Original patch and description from Neil Brown <neilb@suse.de>,
merged and adapted to splice branch by me. Neils text follows:
__generic_file_splice_read() currently samples the i_size at the start
and doesn't do so again unless it needs to call ->readpage to load
a page. After ->readpage it has to re-sample i_size as a truncate
may have caused that page to be filled with zeros, and the read()
call should not see these.
However there are other activities that might cause ->readpage to be
called on a page between the time that __generic_file_splice_read()
samples i_size and when it finds that it has an uptodate page. These
include at least read-ahead and possibly another thread performing a
read
So we must sample i_size *after* it has an uptodate page. Thus the
current sampling at the start and after a read can be replaced with a
sampling before page addition into spd.
