bd2ebb612d drm/i915: Further reduce the diff with Linux 3.8
There is no functional change. The goal is to ease the future update to
Linux 3.8's i915 driver.

d836c868a8 i915_gem_do_execbuffer() holds the pages backing each relocation region for
various reasons while executing user commands.  After these commands are
completed, the pages backing the relocation regions are unheld.

Since relocation regions do not have to be page aligned, the code in
validate_exec_list() allocates 2 extra page pointers in the array of
held pages populated by vm_fault_quick_hold_pages().  However, the cleanup
code that unheld the pages always assumed that only the buffer size /
PAGE_SIZE pages were used.  This meant that non-page aligned buffers would
not unheld the last 1 or 2 pages in the list.  Fix this by saving the
number of held pages returned by vm_fault_quick_hold_pages() for each
relocation region and using this count during cleanup.

2ad026889e Most error cases in i915_gem_do_execbuffer() jump to one of two labels to
release resources (such as unholding pages) when errors occur.  Some
recently added error checks return immediately instead of jumping to a
label resulting in leaks.  Fix these to jump to a label to do cleanup
instead.

455fa6518a drm: Update the device-independent code to match Linux 3.8.13
This update brings few features:
    o  Support for the setmaster/dropmaster ioctls. For instance, they
       are used to run multiple X servers simultaneously.
    o  Support for minor devices. The only user-visible change is a new
       entry in /dev/dri but it is useless at the moment. This is a
       first step to support render nodes [1].

The main benefit is to greatly reduce the diff with Linux (at the
expense of an unreadable commit diff). Hopefully, next upgrades will be
easier.

No updates were made to the drivers, beside adapting them to API
changes.

47671d1bab An update for the i915 GPU driver, which brings the code up to Linux
commit 4d93914ae3db4a897ead4b.  Some related drm infrastructure
changes are imported as needed.

Biggest update is the rewrite of the i915 gem io to more closely
follow Linux model, althought the mechanism used by FreeBSD port is
different.

73547eeae9 drm/i915: Add HW context support
This feature is required by Mesa 9.2+. Without this, a GL application
crashes with the following message:
    # glxinfo
    name of display: :0.0
    Gen6+ requires Kernel 3.6 or later.
    Assertion failed: (ctx->Version > 0), function handle_first_current,
      file ../../src/mesa/main/context.c, line 1498.
    Abort (core dumped)

Now, Mesa 10.2.4 and 10.3-rc3 works fine:
    # glxinfo
    name of display: :0
    display: :0  screen: 0
    direct rendering: Yes
    ...
    OpenGL renderer string: Mesa DRI Intel(R) 965GM
    OpenGL version string: 2.1 Mesa 10.2.4
    ...

The code was imported from Linux 3.8.13.

46932515ac Disable end of buffer fixup by default. New DDX does not need this, and
since batch_len is unused by Linux driver, it seems that it is sometimes
gets passed wrong. This causes command buffer corruption and GPU hung.

Old GEMified DDX drivers that needs this workaround are not supported.

e27f871969 Add the code for new Intel GPU driver, which supports GEM, KMS and
works with new generations of GPUs (IronLake, SandyBridge and
supposedly IvyBridge).

The driver is not connected to the build yet.
