Can we do this without upping the driver majors? we may have to add
setparam support... my problem is after this chan

Hi, All.
I'd like to bring in the hashed map lookup from the drm-ttm-branch to
CVS. It changes the drmmap() map lookup from a linked list search to a
hash lookup.
This means that the user_token that identifies the map in user space
becomes an arbitrary hash key in the range 0x1000 to 0x9
