This patch will break 64 bit systems. It only works on your system
because drm cuts 32 bits off the pointer.
This is what drm expects to see:
64_bit_pointer
for every buffer
32_bit_index
Thus, rmesa->rmm->u_list[id].age is at 64_bit_pointer[32_bit_index] .
Since age and h_pending go in pairs, rmesa->rmm->u_list[id].h_pending
is at 64_bit_pointer[32_bit_index + 1] .
Hope this clears out things a bit.
