There are two chunks of code we need to do this. The first one is the code
to insert and remove the pages from the GART, the second is the code to build
page table lists from the GEM object. Surprisingly this latter one doesn't seem
to have a nice GEM helper.
While we are at it we can begin dismantling the semi redundant struct pg,
and finish pruning out the old now unused gtt code as well as the last bits
of helper glue from the old driver base.

This puts in place the infrastructure for GEM allocators. Our implementation
is fairly simplistic at this point and we don't deal with things like
evicting objects from the GART to make space, nor compaction.
We extent our gtt_range struct to include a GEM object and that allows GEM
to do all the handle management and most of the memory mapping work for us.
This patch also doesn't load GEM pages into the GART so the GEM side isn't
very useful. Before we can do that a fair bit of work is needed reworking the
internal GTT code.

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.

After 57db4e8d73 changed eCryptfs to
write-back caching, eCryptfs page writeback updates the lower inode
times due to the use of vfs_write() on the lower file.
To preserve inode metadata changes, such as 'cp -p' does with
utimensat(), we need to flush all dirty pages early in
ecryptfs_setattr() so that the user-updated lower inode metadata isn't
clobbered later in writeback.

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.

When failing to read the lower file's crypto metadata during a lookup,
eCryptfs must continue on without throwing an error. For example, there
may be a plaintext file in the lower mount point that the user wants to
delete through the eCryptfs mount.
If an error is encountered while reading the metadata in lookup(), the
eCryptfs inode's size could be incorrect. We must be sure to reread the
plaintext inode size from the metadata when performing an open() or
setattr(). The metadata is already being read in those paths, so this
adds minimal performance overhead.
This patch introduces a flag which will track whether or not the
plaintext inode size has been read so that an incorrect i_size can be
fixed in the open() or setattr() paths.

For any given lower inode, eCryptfs keeps only one lower file open and
multiplexes all eCryptfs file operations through that lower file. The
lower file was considered "persistent" and stayed open from the first
lookup through the lifetime of the inode.
This patch keeps the notion of a single, per-inode lower file, but adds
reference counting around the lower file so that it is closed when not
currently in use. If the reference count is at 0 when an operation (such
as open, create, etc.) needs to use the lower file, a new lower file is
opened. Since the file is no longer persistent, all references to the
term persistent file are changed to lower file.
Locking is added around the sections of code that opens the lower file
and assign the pointer in the inode info, as well as the code the fputs
the lower file when all eCryptfs users are done with it.
This patch is needed to fix issues, when mounted on top of the NFSv3
client, where the lower file is left silly renamed until the eCryptfs
inode is destroyed.
