In the process of adding GEM support for omapdrm driver, I noticed that I was adding code for creating/freeing mmap offsets which was virtually identical to what was already duplicated in i915 and gma500 drivers. And the code for attach/detatch_pages was quite similar as well.
Rather than duplicating the code a 3rd time, it seemed like a good idea to move it to the GEM core.
Note that I don't actually have a way to test psb or i915, but the changes seem straightforward enough.
v1: initial patches v2: rebase + add common get/put_pages functions
