For the moment, the tee subsystem only makes sense in combination with
the op-tee driver that depends on ARM_SMCCC, so let's hide the subsystem

Pull TEE driver infrastructure and OP-TEE drivers from Arnd Bergmann:
"This introduces a generic TEE framework in the kernel, to handle
trusted environemtns (security coprocessor or software implementations
such as OP-TEE/TrustZone). I'm sending it separately from the other
arm-soc driver changes to give it a little more visibility, once the
subsystem is merged, we will likely keep this in the arm₋soc drivers
branch or have the maintainers submit pull requests directly,
depending on the patch volume.
I have reviewed earlier versions in the past, and have reviewed the
latest version in person during Linaro Connect BUD17.
Here is my overall assessment of the subsystem:
- There is clearly demand for this, both for the generic
infrastructure and the specific OP-TEE implementation.
- The code has gone through a large number of reviews, and the review
comments have all been addressed, but the reviews were not coming
up with serious issues any more and nobody volunteered to vouch for
the quality.
- The user space ioctl interface is sufficient to work with the
OP-TEE driver, and it should in principle work with other TEE
implementations that follow the GlobalPlatform[1] standards, but it
might need to be extended in minor ways depending on specific
requirements of future TEE implementations
- The main downside of the API to me is how the user space is tied to
the TEE implementation in hardware or firmware, but uses a generic
way to communicate with it. This seems to be an inherent problem
with what it is trying to do, and I could not come up with any
better solution than what is implemented here.

It looks like simply writing all the cursor register every single
time might be slightly faster than checking to see of each of
them need to be written. So if any other register apart from
CURPOS needs to be written let's just write all the registers.
CURPOS is left as a special case mainly for 845/865 where we have to
disable the cursor to change many of the cursor parameters. This
introduces a slight chance of the cursor flickering when things get
updated (since we're not currently doing the vblank evade for cursor
updates). If we write CURPOS alone then that obviously can't happen.
And let's follow the same pattern in the i9xx code just for symmetry.
I wasn't able to see a singificant performance difference between
this and just writing all the registers unconditionally.

The cursor plane doesn't have any kind of source offset register, so
the only form of panning possible is via a the base address register.
The alignment required by CURBASE ranges from 32B to 16KiB depending
on the platform. Let's make sure the user didn't ask for something
we can't do.
Obviously this is impossible to hit via the legacy cursor ioctl since
the src offsets are always 0, but via the plane/atomic ioctls the user
can ask for pretty much anything so we have to deal with this.

IVB introduced the CUR_FBC_CTL register which allows reducing the cursor
height down to 8 lines from the otherwise square cursor dimensions.
Implement support for it. CUR_FBC_CTL can't be used when the cursor

The cursor code currently ignores fb->pitches[0] (except when creating
the fb itself), and just uses the cursor_width*4 as the stride. Let's
make sure fb->pitches[0] actually matches what we expect it to be.
We can also relax the stride vs. cursor width relationship on 845/865
since the stride is programmed separately. The only constraint is that
width*cpp doesn't exceed the stride, and that's already been checked
by the core since it makes sure the entire plane fits within the fb.
We can also drop the bo size check as that's already checked when
we create the fb. That is the fb is guaranteed to fit within the bo.

Supposedly on some platforms we can get extra atomicity guarantees for
CURPOS if we write it between the CURCNTR and CURBASE. Let's move the
CURPOS handling into the platform specific hooks to make the possible
without having to pass the calculated CURPOS around. And while at it,
do the same for the CURBASE to avoid passing that either.

Pull overlayfs update from Miklos Szeredi:
"The biggest part of this is making st_dev/st_ino on the overlay behave
like a normal filesystem (i.e. st_ino doesn't change on copy up,
st_dev is the same for all files and directories). Currently this only
works if all layers are on the same filesystem, but future work will
move the general case towards more sane behavior.
There are also miscellaneous fixes, including fixes to handling
append-only files. There's a small change in the VFS, but that only
has an effect on overlayfs, since otherwise file->f_path.dentry->inode
and file_inode(file) are always the same"

Move cursor_base, cursor_cntl, and cursor_size from intel_crtc
into intel_plane so that we don't need the crtc for cursor stuff
so much.
Also entirely nuke cursor_addr which IMO doesn't provide any benefit
since it's not actually used by the cursor code itself. I'm not 100%
sure what the SKL+ DDB is code is after by looking at cursor_addr so
I just make it do its checks unconditionally. If that's not correct
then we should likely replace it with somehting like
plane_state->visible.

Pull ceph updates from Ilya Dryomov:
"The two main items are support for disabling automatic rbd exclusive
lock transfers from myself and the long awaited -ENOSPC handling
series from Jeff.
The former will allow rbd users to take advantage of exclusive lock's

of who owns the lock. With the latter in place, we will abort
filesystem writes on -ENOSPC instead of having them block
indefinitely.
Beyond that we've got the usual pile of filesystem fixes from Zheng,
some refcount_t conversion patches from Elena and a patch for an
ancient open() flags handling bug from Alexander"

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.
The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.
Note that only cris and tile have more directories than only asm:
- arch-v[10|32] for cris;
- arch for tile.

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.
In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.
After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):

exported directories (like .install or .install.cmd).

files listed by:
- include/uapi/asm-generic/Kbuild.asm;
- arch/<arch>/include/uapi/asm/Kbuild;
- arch/<arch>/include/asm/Kbuild.
