compat: backport fb_info->skip_vt_switch using a static inline

Commit 3cf2667 as of next-20130301 extended the struct fb_info
with a skip_vt_switch to allow drivers to skip the VT switch
at suspend/resume time. For older kernels we can skip this
as all this switch does is call pm_vt_switch_required() with true
or false depending on this new flag and later
pm_vt_switch_unregister() would not have been made.

compat-drivers was backporting this using #ifdef's but by
integrating a static inline we'd reduce the number of lines
to backport to just 1 line replacement. This would be something
like:

  -       info->skip_vt_switch = true;
  +       fb_enable_skip_vt_switch(info);

For kernels >= 3.10 we'd set the attribute as we do upstream,
for older kernels this would be a no-op.

If this static inline would have been added upstream it would
have meant this collateral evolution would require just adding
a no-op static inline to backport, and no changes as the above
example hunk for every driver that requires the change.

If this static inline ends up upstream *now* it means we do *not*
require the type of hunk above for every driver that requires
the change.

All the code would be left intact !

This is a linux-next 'data structure element collateral evolution'.

compat-drivers: backport fb_info->skip_vt_switch using ifdefs

Commit 3cf2667 as of next-20130301 extended the struct fb_info
with a skip_vt_switch to allow drivers to skip the VT switch
at suspend/resume time. For older kernels we can skip this

or false depending on this new flag and later
pm_vt_switch_unregister() would not have been made.

This patch cannot be broken down further so I'm pegging
this as the first one with 4 digits under the DRM folder
for collateral evolutions. This reflects its as atomic as
is possible. As we'll see on the next commit, these type
of collateral evolutions can best be backported not by
keeping ifdef's as below but instead by using a wrapper
caller, to help reduce with the amount of lines of code
we need. If a static inline is added upstream for these
changes, then no code is required for backporting, at all,
we'd just implement the static inline later upstream as
a no-op.

The tradeoffs to consider for this is if we can live with
these practices upstream, we may be able to support full
subsystems only with a compat module, and no need for
patches. This also means less code and likely less bugs
on the distribution front when backporting is required.
At least IMHO this may be worthy to consider at least to
support kernels listed as supported on kernel.org. We could
just leave the ifdef hell to older unsupported kernels.

    lib/scatterlist: sg_page_iter: support sg lists w/o backing pages

    The i915 driver uses sg lists for memory without backing 'struct page'
    pages, similarly to other IO memory regions, setting only the DMA
    address for these. It does this, so that it can program the HW MMU
    tables in a uniform way both for sg lists with and without backing pages.

    Without a valid page pointer we can't call nth_page to get the current
    page in __sg_page_iter_next, so add a helper that relevant users can

    difficult to use for input because one cannot determine if one event
    occurred before another or for how long a key was pressed.

    However, the timestamp field is part of the kernel ABI, and cannot be
    changed without possibly breaking existing users.

    This patch adds a new IOCTL that allows a clockid to be set in the
    evdev_client struct that will specify which time base to use for event
    timestamps (ie: CLOCK_MONOTONIC instead of CLOCK_REALTIME).

    For now we only support CLOCK_MONOTONIC and CLOCK_REALTIME, but
    in the future we could support other clockids if appropriate.

    The default remains CLOCK_REALTIME, so we don't change the ABI.

    drm: add support for monotonic vblank timestamps

    Jumps in the vblank and page flip event timestamps cause trouble for
    clients, so we should avoid them. The timestamp we get currently with
    gettimeofday can jump, so use instead monotonic timestamps.

    For backward compatibility use a module flag to revert back to using
    gettimeofday timestamps. Add also a DRM_CAP_TIMESTAMP_MONOTONIC flag
    that is simply a read only version of the module flag, so that clients
    can query this without depending on sysfs.

compat: fix cordic backport header

10f8113ecb76eea72f96c7cfb72d7fed7c282565
v3.1-rc1~24^2~10^2^2~515

The cordic backport added the cordic library
and the cordic header. It correctly only compiled
cordic for kernels < 3.1 but the header however was
left intact. This is non-issue until cordic itself
gets updated with some new features or changes but
also an issue was created when we switched the
backort namespace. The issue is that the header
declares backport_cordic_calc_iq() exists while
it actually is not compiled on newer kernels.

Fix this by doing the kernel revision check on the
backported header, otherwise use #include_next to
get the next header, the proper kernel header.

This does not have to be added to the older releases
given that the header is the same for older kernels,
and we are not exporting the symbol twice given that
the proper check was already in place for cordic.c.

    scatterlist: add sg_alloc_table_from_pages function

    This patch adds a new constructor for an sg table. The table is constructed
    from an array of struct pages. All contiguous chunks of the pages are merged
    into a single sg nodes. A user may provide an offset and a size of a buffer if
    the buffer is not page-aligned.

    The function is dedicated for DMABUF exporters which often perform conversion
    from an page array to a scatterlist. Moreover the scatterlist should be
    squashed in order to save memory and to speed-up the process of DMA mapping
    using dma_map_sg.

    The code is based on the patch 'v4l: vb2-dma-contig: add support for
    scatterlist in userptr mode' and hints from Laurent Pinchart.
