MFC 288452,289719:
288452: 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.
Note that stable/9 does not have the "recently added" error checks, but it does have some older error checks (that were are no longer present in stable/10 and head) that have the same bug and this fixes those instead.
289719: 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.

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.

drm: Sort connector modes based on vrefresh
Keeping the modes sorted by vrefresh before the pixel clock makes the mode list somehow more pleasing to the eye.

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.
This an MFC of r271705.
