Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux

Pull i2c-embedded changes from Wolfram Sang:
 "Major changes:

   - lots of devicetree additions for existing drivers.  I tried hard to
     make sure the bindings are proper.  In more complicated cases, I
     requested acks from people having more experience with them than
     me.  That took a bit of extra time and also some time went into
     discussions with developers about what bindings are and what not.
     I have the feeling that the workflow with bindings should be
     improved to scale better.  I will spend some more thought on
     this...

   - i2c-muxes are succesfully used meanwhile, so we dropped
     EXPERIMENTAL for them and renamed the drivers to a standard pattern
     to match the rest of the subsystem.  They can also be used with
     devicetree now.

   - ixp2000 was removed since the whole platform goes away.

   - cleanups (strlcpy instead of strcpy, NULL instead of 0)

   - The rest is typical driver fixes I assume.

  All patches have been in linux-next at least since v3.4-rc6."

Fixed up trivial conflict in arch/arm/mach-lpc32xx/common.c due to the
same patch already having come in through the arm/soc trees, with
additional patches on top of it.

builddeb: include autogenerated header files

After 303395ac3bf3e2cb488435537d416bc840438fcb, some headers are
autogenerated. Include these autogenerated headers (mainly
unistd_32_ia32.h) in out-of-tree builds to allow DKMS modules to be
built succesfully.

Merge branch 'generic-string-functions'

This makes <asm/word-at-a-time.h> actually live up to its promise of
allowing architectures to help tune the string functions that do their
work a word at a time.

David had already taken the x86 strncpy_from_user() function, modified
it to work on sparc, and then done the extra work to make it generically
useful.  This then expands on that work by making x86 use that generic
version, completing the circle.

But more importantly, it fixes up the word-at-a-time interfaces so that
it's now easy to also support things like strnlen_user(), and pretty
much most random string functions.

David reports that it all works fine on sparc, and Jonas Bonn reported
that an earlier version of this worked on OpenRISC too.  It's pretty
easy for architectures to add support for this and just replace their
private versions with the generic code.

* generic-string-functions:
  sparc: use the new generic strnlen_user() function
  x86: use the new generic strnlen_user() function
  lib: add generic strnlen_user() function
  word-at-a-time: make the interfaces truly generic
  x86: use generic strncpy_from_user routine
xfrm: take net hdr len into account for esp payload size calculation

Corrects the function that determines the esp payload size. The calculations
done in esp{4,6}_get_mtu() lead to overlength frames in transport mode for
certain mtu values and suboptimal frames for others.

According to what is done, mainly in esp{,6}_output() and tcp_mtu_to_mss(),
net_header_len must be taken into account before doing the alignment
calculation.

ipv6: fix incorrect ipsec fragment

Since commit ad0081e43a
"ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed"
the fragment of packets is incorrect.
because tunnel mode needs IPsec headers and trailer for all fragments,
while on transport mode it is sufficient to add the headers to the
first fragment and the trailer to the last.

so modify mtu and maxfraglen base on ipsec mode and if fragment is first
or last.

with my test,it work well(every fragment's size is the mtu)
and does not trigger slow fragment path.

Changes from v1:
	though optimization, mtu_prev and maxfraglen_prev can be delete.
	replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL.
	add fuction ip6_append_data_mtu to make codes clearer.

Merge tag 'omapdss-for-3.5' of git://github.com/tomba/linux into fbdev-next

Omapdss driver changes for 3.5 merge window.

Lots of normal development commits, but perhaps most notable changes are:

* HDMI rework to properly decouple the HDMI audio part from the HDMI video part.
* Restructure omapdss core driver so that it's possible to implement device
  tree support. This included changing how platform data is passed to the
  drivers, changing display device registration and improving the panel driver's
  ability to configure the underlying video output interface.
* Basic support for DSI packet interleaving
lib: Fix generic strnlen_user for 32-bit big-endian machines

The aligned_byte_mask() definition is wrong for 32-bit big-endian
machines: the "7-(n)" part of the definition assumes a long is 8
bytes.  This fixes it by using BITS_PER_LONG - 8 instead of 8*7.
Tested on 32-bit and 64-bit PowerPC.
