Linus Torvalds 038a5008b2 Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6
* 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (867 commits)
  [SKY2]: status polling loop (post merge)
  [NET]: Fix NAPI completion handling in some drivers.
  [TCP]: Limit processing lost_retrans loop to work-to-do cases
  [TCP]: Fix lost_retrans loop vs fastpath problems

  [TCP]: Kill almost unused variable pcount from sacktag
  [TCP]: Fix mark_head_lost to ignore R-bit when trying to mark L
  [TCP]: Add bytes_acked (ABC) clearing to FRTO too
  [IPv6]: Update setsockopt(IPV6_MULTICAST_IF) to support RFC 3493, try2
  [NETFILTER]: x_tables: add missing ip6t_modulename aliases
  [NETFILTER]: nf_conntrack_tcp: fix connection reopening
  [QETH]: fix qeth_main.c
  [NETLINK]: fib_frontend build fixes
  [IPv6]: Export userland ND options through netlink (RDNSS support)

  ...

Fix up conflicts manually in Documentation/feature-removal-schedule.txt
and my new least favourite crap, the "mod_devicetable" support in the
files include/linux/mod_devicetable.h and scripts/mod/file2alias.c.

(The latter files seem to be explicitly _designed_ to get conflicts when
different subsystems work with them - that have an absolutely horrid
lack of subsystem separation!)

Trent Piepho a991f44b79 V4L/DVB (6316): Change list_for_each+list_entry to list_for_each_entry
The rest of V4L files.

There is one list_for_each+list_entry in cpia_pp.c that
wasn't changed because it expects the loop iterator to remain NULL if
the list is empty.

A bug in vivi is fixed; the 'safe' version needs to be used because the loop
deletes the list entries.

Simplify a second loop in vivi and get rid if an un-used variable in that loop.

A couple loops weren't changed because they expected the loop iterator

Trent Piepho 805a439241 V4L/DVB (6313): ivtv: Replace list_for_each+list_entry with list_for_each_entry
Also fixed a few cases of cut&paste errors where 'buf' would be set to the
first entry in the list prior to be used as the loop iterator.  In one case
the value of buf was used before it was changed, but the rest were
unnecessary.

There was one list_for_each+list_entry loop that wasn't changed, since it
depending on the loop iterator being left as NULL if the list was empty.

This patch renames it, to avoid confusion with the previous kernel API, doing:

Also, the operations is now part of the function parameter. The function will
also add a test if this is defined, otherwise producing BUG.

Trent Piepho 5a3ebe8755 V4L/DVB (6283): videobuf: Remove references to old Kconfig option name
CONFIG_VIDEO_BUF_DVB became CONFIG_VIDEOBUF_DVB.

But in these cases, it makes more sense to use CONFIG_VIDEO_SAA7134_DVB
or CONFIG_VIDEO_CX88_DVB_MODULE depending on the driver.

The reference in cx23885.h should just be removed, as the code there needs to
be included if DVB is on or off.  I do not think you can even compile the
cx23885 driver without DVB.  It's clearly just leftover from when the file was
obvious copied from the cx88 driver (which is not mentioned in the copyright
BTW).
