Merge tag 'fbdev-updates-for-3.7' of git://github.com/schandinat/linux-2.6

2012-10-12T01:21:02+00:00

Pull fbdev updates from Florian Tobias Schandinat:
 "This includes:
   - large updates for OMAP
     - basic OMAP5 DSS support for DPI and DSI outputs
     - large cleanups and restructuring
   - some update to Exynos and da8xx-fb
   - removal of the pnx4008 driver (arch removed)
   - various other small patches"

Fix up some trivial conflicts (mostly just include line changes, but
also some due to the renaming of the deferred work functions by Tejun).

mm: kill vma flag VM_RESERVED and mm->reserved_vm counter

2012-10-09T07:22:19+00:00

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.

"this patch set updates exynos drm framework and includes minor fixups.
and this pull request except hdmi device tree support patch set posted
by Rahul Sharma because that includes media side patch so for this
patch set, we may have git pull one more time in addition, if we get
an agreement with media guys. for this patch, you can refer to below link,
        http://comments.gmane.org/gmane.comp.video.dri.devel/74504

 this pull request adds hdmi device tree support
and includes related patch set such as disabling of hdmi internal
interrupt, suppport for platform variants for hdmi and mixer,
support to disable video processor based on platform type and
removal of drm common platform data. as you know, this patch
set was delayed because it included an media side patch. so for this,
we got an ack from v4l2-based hdmi driver author, Tomasz Stanislawski."

drm: exynos: hdmi: remove drm common hdmi platform data struct

2012-10-05T10:15:16+00:00

exynos-drm-hdmi need context pointers from hdmi and mixer. These
pointers were expected from the plf data. Cleaned this dependency
by exporting i/f which are called by hdmi, mixer driver probes
for setting their context.

This patch removed the is_v13 variable from the hdmi driver context.
It is replaced with condition check for the hdmi version. This cleans

This patch adds support for disabling the video processor code based
on the platform type. This is done based on a field in the mixer driver
data which changes with the platform variant.
