Linus Torvalds 7307c00f33 arm-soc: late OMAP changes
This branch contains changes for OMAP that came in late during the release
 staging, close to when the merge window opened.
 
 It contains, among other things:
 
 - OMAP PM fixes and some patches for audio device integration
 - OMAP clock fixes related to common clock conversion
 - A set of patches cleaning up WFI entry and blocking.
 - A set of fixes and IP block support for PM on TI AM33xx SoCs (Beaglebone, etc)
 - A set of smaller fixes and cleanups around AM33xx restart and revision
   detection, as well as removal of some dead code (CONFIG_32K_TIMER_HZ)

Pull s390 update from Martin Schwidefsky:
 "The most prominent change in this patch set is the software dirty bit
  patch for s390.  It removes __HAVE_ARCH_PAGE_TEST_AND_CLEAR_DIRTY and
  the page_test_and_clear_dirty primitive which makes the common memory
  management code a bit less obscure.

  Heiko fixed most of the PCI related fallout, more often than not
  missing GENERIC_HARDIRQS dependencies.  Notable is one of the 3270
  patches which adds an export to tty_io to be able to resize a tty.

  The rest is the usual bunch of cleanups and bug fixes."

Linus Torvalds 3298a3511f arm-soc: multiplatform support
Converting more ARM platforms to multiplatform support. This time, OMAP
 gets converted, which is a major step since this is by far the largest
 platform in terms of code size. The same thing happens to the vt8500
 platform.
 
 Conflicts include:
 * Two mach/uncompress.h files are removed, the changes made to them
   elsewhere can be discarded now.
 * Moving the OMAP4 irq_match array has context clashes with turning
   omap4_sar_ram_init into an omap_early_initcall()

Mauro Carvalho Chehab ac89758697 Revert "[media] dvb_frontend: return -ENOTTY for unimplement IOCTL"
As reported by Klaus Schmidinger:
 "In VDR I use an ioctl() call with FE_READ_UNCORRECTED_BLOCKS on a
  device (using stb0899).  After this call I check 'errno' for
  EOPNOTSUPP to determine whether this device supports this call.  This
  used to work just fine, until a few months ago I noticed that my
  devices using stb0899 didn't display their signal quality in VDR's OSD
  any more.  After further investigation I found that
  ioctl(FE_READ_UNCORRECTED_BLOCKS) no longer returns EOPNOTSUPP, but
  rather ENOTTY.  And since I stop getting the signal quality in case
  any unknown errno value appears, this broke my signal quality query
  function."

While the changes reflect what is there at:

  http://comments.gmane.org/gmane.linux.kernel/1235728

it does cause regression on userspace.  So, revert it to stop the
damage.

This reverts commit 177ffe506c ("[media] dvb_frontend: return -ENOTTY
for unimplement IOCTL").

Merge branch 'omap/multiplatform-fixes', tag 'v3.8-rc5' into next/multiplatform

The omap multiplatform support uncovered a bug in the cwdavinci_cpdma
code and was missing two drivers that are enabled now but are not
quite ready for multiplatform, as found by allyesconfig builds.

There is also a conflict generated by automated merge in
arch/arm/mach-omap2/drm.c between a bug fix that went into v3.8-rc5
and a different version of the same fix that went into the
omap/multiplatform branch. This merge removes the extraneous
 #include that was causing build errors.

on multiplatform kernels, which causes a problem
since the driver tries to incude the davinci
platform specific mach/hardware.h file. Fortunately
that file is not required at all in the driver,
so we can simply remove the #include statement.

Without this patch, building allyesconfig results in:

drivers/media/platform/davinci/vpss.c:28:27: fatal error: mach/hardware.h: No such file or directory
compilation terminated.

Christoph Nuscheler ed72d37a33 [media] media: Add 0x3009 USB PID to ttusb2 driver (fixed diff)
The "Technisat SkyStar USB plus" is a TT-connect S-2400 clone, which the
V4L-DVB drivers already support. However, some of these devices (like
mine) come with a different USB PID 0x3009 instead of 0x3006.

There have already been patches simply overwriting the USB PID in
dvb-usb-ids.h. Of course these patches were rejected because they would
have disabled the 0x3006 PID.

This new patch adds the 0x3009 PID to dvb-usb-ids.h, and adds references
to it within the ttusb2.c driver. PID 0x3006 devices will continue to work.

The only difference between the two hardware models seems to be the
EEPROM chip. In fact, Windows BDA driver names the 0x3009 device with a
"(8 kB EEPROM)" suffix. In spite of that, the 0x3009 device works
absolutely flawlessly using the existing ttusb2 driver.

Frank Schaefer 33f6984ece [media] em28xx: fix analog streaming with USB bulk transfers
With the conversion to videobuf2, some unnecessary calls of
em28xx_set_alternate() have been removed. It is now called at analog streaming
start only.
This has unveiled a bug that causes USB bulk transfers to fail with all urbs
having status -EVOERFLOW.
The reason is, that for bulk transfers usb_set_interface() needs to be called
even if the previous alt setting was the same (side note: bulk transfers seem
to work only with alt=0).
While it seems to be NOT necessary for isoc transfers, it's reasonable to just
call usb_set_interface() unconditionally in em28xx_set_alternate().
Also add a comment that explains the issue to prevent regressions in the future.

The ttusb_process_muxpack() function is only called from
ttusb_process_frame().  Before calling, it verifies that len >= 2.  The
problem is that len == 2 is not valid and would lead to an array
underflow.
Odd number values for len are also invalid and would lead to reading
