At the moment we don't do any page backing for the GTT so only the stolen
area pages will actually work. That is fine for our initial framebuffer and
a bit of testing but will need resolution (including alternate mmap methods
and the like for s/g areas) eventually.
Rather than use some of the overcomplex stuff in the DRM we use the existing
Linux resource allocators to hand out framebuffers and the like. This also has
the nice result that /proc/iomem shows the allocations.

stli_brdstats is defined as global variable. After de-BKL-ization in
the patch b4eda9cb48 an access to the variable is not serialized
anymore. This leads to the race window between the check and the use
in stli_getbrdstats():
if (copy_from_user(&stli_brdstats, bp, sizeof(combrd_t)))
return -EFAULT;
if (stli_brdstats.brd >= STL_MAXBRDS) <<<
return -ENODEV;
brdp = stli_brds[stli_brdstats.brd]; <<<
If one process calls COM_GETBRDSTATS ioctl() with sane .brd, second
process calls COM_GETBRDSTATS ioctl() with invalid .brd, and the
second process' copy_from_user() executes exactly between the check and
stli_brds[] indexation of the first process, then the first process gets
contents of memory at *stli_brds[stli_brdstats.brd] address. Also
the resulting .nrpanels field may be too big, in this case
stli_brdstats.panels array overflows.

2. The firmware and the board data files are different
