8287361abc ARM: arm-soc: Header cleanups
This is a collection of header file cleanups, mostly for OMAP and AT91,
 that keeps moving the platforms in the direction of multiplatform by
 removing the need for mach-dependent header files used in drivers and
 other places.

cff2f741b8 Driver core updates for 3.8-rc1
Here's the large driver core updates for 3.8-rc1.
 
 The biggest thing here is the various __dev* marking removals.  This is
 going to be a pain for the merge with different subsystem trees, I know,
 but all of the patches included here have been ACKed by their various
 subsystem maintainers, as they wanted them to go through here.
 
 If this is too much of a pain, I can pull all of them out of this tree
 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.
 
 All of these have (much to Stephen's annoyance), been in linux-next for
 a while.

Commit 952cbaaa9b8beacc425f9aedf370468cbb737a2c (OMAPFB: Change
dssdev->manager references) added checks for OMAPFB_WAITFORVSYNC ioctl
to verify that the display, output and overlay manager exist. However,
the code erroneously uses && for each part, which means that
OMAPFB_WAITFORVSYNC may crash the kernel if no display, output or
manager is associated with the framebuffer.

This patch fixes the issue by using ||.

Backend drivers shouldn't transistion to CLOSED unless the frontend is
CLOSED.  If a backend does transition to CLOSED too soon then the
frontend may not see the CLOSING state and will not properly shutdown.

So, treat an unexpected backend CLOSED state the same as CLOSING.

Commit 185bae1095188aa199c9be64d6030d8dbfc65e0a ("OMAPDSS: DSS: Cleanup
cpu_is_xxxx checks") broke the DSS clocks configuration by erroneously
using the clock parameters applicable to all other OMAP34xx SoCs for the
OMAP363x. This went unnoticed probably because the cpu_is_omap34xx()
class check wasn't seen as matching the OMAP363x subclass.

Fix it by checking for the OMAP363x subclass before checking for the
OMAP34xx class.

If dsi_get_dsidev_from_id() is called with a DSI module id that does not
exist on the board, the function will crash as omap_dss_get_output()
will return NULL.

This happens on omap3 boards when dumping DSI clocks, as the dumping
code will try to get the dsidev for DSI modules 0 and 1, but omap3 only
has DSI module 0.

Also clean up the id -> output mapping, so that if the function is
called with invalid module ID it will return NULL.

There's no need to have this file in plat/fpga.h. We can
make it local to plat-omap replacing fpga_read/write
functions directly with readb/writeb as that's how
they are already defined in fpga.h.

Note that 2420 based H4 is also using the fpga, so let's
keep the led support around in plat-omap until we flip
over mach-omap2 to device tree.

406c8563a7 OMAP: VRFB: convert vrfb to platform device
This patch converts vrfb library into a platform device, in an effort to
remove omap dependencies.

The platform device is registered in arch/arm/plat-omap/fb.c and
assigned resources depending on whether running on omap2 or omap3.

The vrfb driver will parse those resources and use them to access vrfb
configuration registers and the vrfb virtual rotation areas.

2474542f64 pwm: Changes for v3.7-rc1
All legacy PWM providers have now been moved to the PWM subsystem. The
 plan for 3.8 is to adapt all board files to provide a lookup table for
 PWM devices in order to get rid of the global namespace. Subsequently,
 users of the legacy pwm_request() and pwm_free() functions can be
 migrated to the new pwm_get() and pwm_put() functions. Once this has
 been completed, the legacy API and the compatibility code in the core
 can be removed.
 
 In addition to the above, these changes also add support for configuring
 the polarity of a PWM signal (currently only supported on ECAP and
 EHRPWM) and include a much needed rework of the i.MX driver. Managed
 functions to obtain and release a PWM device (devm_pwm_get() and
 devm_pwm_put()) have been added and the pwm-backlight driver has been
 updated to use them. If the PWM subsystem hasn't been enabled, dummy
 functions are provided that allow the subsystem to safely compile out.
 
 Some common checks on input parameters have been moved to the core and
 removed from the drivers. Finally, a small fix corrects the description
 of the PWM specifier's second cell in the device tree representation.

0febd3bccf Omapdss driver changes for the 3.7 merge window.
Notable changes:
 
 * Basic writeback support for DISPC level. Writeback is not yet usable, though,
   as we need higher level code to actually expose the writeback feature to
   userspace.
 * Rewriting the omapdss output drivers. We're trying to remove the hard links
   between the omapdss and the panels, and this rewrite work moves us closer to
   that goal.
 * Cleanup and restructuring patches that have been made while working on device
   tree support for omapdss. Device tree support is still some way ahead, but
   these patches are good cleanups in themselves.
 * Basic OMAP5 DSS support for DPI and DSI outputs.
 * Workaround for the problem that GFX overlay's fifo is too small for high
   resolution scenarios, causing underflows.
 * Cleanups that remove dependencies to omap platform code.

8d93241b92 video: mark nuc900fb_map_video_memory as __devinit
nuc900fb_map_video_memory is called by an devinit function
that may be called at run-time, but the function itself is
marked __init and will be discarded after boot.

To avoid calling into a function that may have been overwritten,
mark nuc900fb_map_video_memory itself as __devinit.

Without this patch, building nuc950_defconfig results in:

WARNING: drivers/video/built-in.o(.devinit.text+0x26c): Section mismatch in reference from the function nuc900fb_probe() to the function .init.text:nuc900fb_map_video_memory()
The function __devinit nuc900fb_probe() references
a function __init nuc900fb_map_video_memory().
If nuc900fb_map_video_memory is only used by nuc900fb_probe then
annotate nuc900fb_map_video_memory with a matching annotation.

314e51b985 mm: kill vma flag VM_RESERVED and mm->reserved_vm counter
A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
currently it lost original meaning but still has some effects:

 | effect                 | alternative flags
-+------------------------+---------------------------------------------
1| account as reserved_vm | VM_IO
2| skip in core dump      | VM_IO, VM_DONTDUMP
3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
4| do not mlock           | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP

This patch removes reserved_vm counter from mm_struct.  Seems like nobody
cares about it, it does not exported into userspace directly, it only
reduces total_vm showed in proc.

Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.

remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

60ce70285b pwm-backlight: Use devm_pwm_get() instead of pwm_get()
Managed versions of the pwm_get() and pwm_put() functions were recently
added to the PWM framework. They can be used to simplify cleanup in the
error paths and the device removal callback.

5f3d2f2e1a Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Benjamin Herrenschmidt:
 "Some highlights in addition to the usual batch of fixes:

   - 64TB address space support for 64-bit processes by Aneesh Kumar

   - Gavin Shan did a major cleanup & re-organization of our EEH support
     code (IBM fancy PCI error handling & recovery infrastructure) which
     paves the way for supporting different platform backends, along
     with some rework of the PCIe code for the PowerNV platform in order
     to remove home made resource allocations and instead use the
     generic code (which is possible after some small improvements to it
     done by Gavin).

   - Uprobes support by Ananth N Mavinakayanahalli

   - A pile of embedded updates from Freescale folks, including new SoC
     and board supports, more KVM stuff including preparing for 64-bit
     BookE KVM support, ePAPR 1.1 updates, etc..."

11126c611e Merge branch 'akpm' (Andrew's patch-bomb)
Merge misc patches from Andrew Morton:
 "The MM tree is rather stuck while I wait to find out what the heck is
  happening with sched/numa.  Probably I'll need to route around all the
  code which was added to -next, sigh.

  So this is "everything else", or at least most of it - other small
  bits are still awaiting resolutions of various kinds."
