If we continue to use bitmask for type, we will quickly run out of room
to add new types. Split this up so existing part of bitmask range
continues to function as before, but reserve a chunk of the remaining
space for an integer type-id. Wrap this all up in some type-check
helpers to keep the backwards-compat uglyness contained.

By exporting the ability to map user address and inserting PTEs
representing their backing pages into the GTT, we can exploit UMA in order
to utilize normal application data as a texture source or even as a
render target (depending upon the capabilities of the chipset). This has
a number of uses, with zero-copy downloads to the GPU and efficient
readback making the intermixed streaming of CPU and GPU operations
fairly efficient. This ability has many widespread implications from
faster rendering of client-side software rasterisers (chromium),
mitigation of stalls due to read back (firefox) and to faster pipelining
of texture data (such as pixel buffer objects in GL or data blobs in CL).
v2: Compile with CONFIG_MMU_NOTIFIER
v3: We can sleep while performing invalidate-range, which we can utilise
to drop our page references prior to the kernel manipulating the vma
(for either discard or cloning) and so protect normal users.
v4: Only run the invalidate notifier if the range intercepts the bo.
v5: Prevent userspace from attempting to GTT mmap non-page aligned buffers
v6: Recheck after reacquire mutex for lost mmu.
v7: Fix implicit padding of ioctl struct by rounding to next 64bit boundary.
v8: Fix rebasing error after forwarding porting the back port.
v9: Limit the userptr to page aligned entries. We now expect userspace
to handle all the offset-in-page adjustments itself.
v10: Prevent vma from being copied across fork to avoid issues with cow.
v11: Drop vma behaviour changes -- locking is nigh on impossible.
Use a worker to load user pages to avoid lock inversions.
v12: Use get_task_mm()/mmput() for correct refcounting of mm.
v13: Use a worker to release the mmu_notifier to avoid lock inversion
v14: Decouple mmu_notifier from struct_mutex using a custom mmu_notifer
with its own locking and tree of objects for each mm/mmu_notifier.
v15: Prevent overlapping userptr objects, and invalidate all objects
within the mmu_notifier range
v16: Fix a typo for iterating over multiple objects in the range and
rearrange error path to destroy the mmu_notifier locklessly.
Also close a race between invalidate_range and the get_pages_worker.
v17: Close a race between get_pages_worker/invalidate_range and fresh
allocations of the same userptr range - and notice that
struct_mutex was presumed to be held when during creation it wasn't.
v18: Sigh. Fix the refactor of st_set_pages() to allocate enough memory
for the struct sg_table and to clear it before reporting an error.
v19: Always error out on read-only userptr requests as we don't have the
hardware infrastructure to support them at the moment.
v20: Refuse to implement read-only support until we have the required
infrastructure - but reserve the bit in flags for future use.
v21: use_mm() is not required for get_user_pages(). It is only meant to
be used to fix up the kernel thread's current->mm for use with
copy_user().
v22: Use sg_alloc_table_from_pages for that chunky feeling
v23: Export a function for sanity checking dma-buf rather than encode
userptr details elsewhere, and clean up comments based on
suggestions by Bradley.

A MIPS64 kernel may support ELF files for all 3 MIPS ABIs
(O32, N32, N64). Furthermore, the AUDIT_ARCH_MIPS{,EL}64 token
does not provide enough information about the ABI for the 64-bit
process. As a result of which, userland needs to use complex
seccomp filters to decide whether a syscall belongs to the o32 or n32
or n64 ABI. Therefore, a new arch token for MIPS64/n32 is added so it
can be used by seccomp to explicitely set syscall filters for this ABI.

This is needed because with writeback_cache mode the kernel is responsible
for generating mtime and ctime, but if the underlying filesystem doesn't
support nanosecond granularity then the cache will contain a different

after a cache flush.

File-private locks have been merged into Linux for v3.15, and *now*
people are commenting that the name and macro definitions for the new
file-private locks suck.
...and I can't even disagree. The names and command macros do suck.
We're going to have to live with these for a long time, so it's
important that we be happy with the names before we're stuck with them.
The consensus on the lists so far is that they should be rechristened as
"open file description locks".
The name isn't a big deal for the kernel, but the command macros are not
visually distinct enough from the traditional POSIX lock macros. The
glibc and documentation folks are recommending that we change them to
look like F_OFD_{GETLK|SETLK|SETLKW}. That lessens the chance that a
programmer will typo one of the commands wrong, and also makes it easier
to spot this difference when reading code.
This patch makes the following changes that I think are necessary before
v3.15 ships:
1) rename the command macros to their new names. These end up in the uapi
headers and so are part of the external-facing API. It turns out that
glibc doesn't actually use the fcntl.h uapi header, but it's hard to
be sure that something else won't. Changing it now is safest.
2) make the the /proc/locks output display these as type "OFDLCK"

On some newer laptops with a trackpoint the physical buttons for the
trackpoint have been removed to allow for a larger touchpad. On these
laptops the buttonpad has clearly marked areas on the top which are to be
used as trackpad buttons.
Users of the event device-node need to know about this, so that they can
properly interpret BTN_LEFT events as being a left / right / middle click
depending on where on the button pad the clicking finger is.
This commits adds a INPUT_PROP_TOPBUTTONPAD device property which drivers
for such buttonpads will use to signal to the user that this buttonpad not
only has the normal bottom button area, but also a top button area.

The version of the drm_tegra_submit structure that was merged all the
way back in 3.10 contains a pad field that was originally intended to
properly pad the following __u64 field. Unfortunately it seems like a
different field was dropped during review that caused this padding to
become unnecessary, but the pad field wasn't removed at that time.
One possible side-effect of this is that since the __u64 following the
pad is now no longer properly aligned, the compiler may (or may not)
introduce padding itself, which results in no predictable ABI.
Rectify this by removing the pad field so that all fields are again
naturally aligned. Technically this is breaking existing userspace ABI,
but given that there aren't any (released) userspace drivers that make
use of this yet, the fallout should be minimal.

Pull NVMe driver updates from Matthew Wilcox:
"Various updates to the NVMe driver. The most user-visible change is
that drive hotplugging now works and CPU hotplug while an NVMe drive
is installed should also work better"
* git://git.infradead.org/users/willy/linux-nvme:
NVMe: Retry failed commands with non-fatal errors
NVMe: Add getgeo to block ops
NVMe: Start-stop nvme_thread during device add-remove.
NVMe: Make I/O timeout a module parameter
NVMe: CPU hot plug notification
NVMe: per-cpu io queues

NVMe: Fix divide-by-zero in nvme_trans_io_get_num_cmds
NVMe: IOCTL path RCU protect queue access
NVMe: RCU protected access to io queues
NVMe: Initialize device reference count earlier
NVMe: Add CONFIG_PM_SLEEP to suspend/resume functions
For commands returned with failed status, queue these for resubmission
and continue retrying them until success or for a limited amount of
time. The final timeout was arbitrarily chosen so requests can't be
retried indefinitely.
Since these are requeued on the nvmeq that submitted the command, the
callbacks have to take an nvmeq instead of an nvme_dev as a parameter
so that we can use the locked queue to append the iod to retry later.
The nvme_iod conviently can be used to track how long we've been trying
to successfully complete an iod request. The nvme_iod also provides the
nvme prp dma mappings, so I had to move a few things around so we can
keep those mappings.

As reported by Linus, make headers_check is reporting:
usr/include/linux/v4l2-common.h:72: found __[us]{8,16,32,64} type without #include <linux/types.h>
which seems to have come in through commits 777f4f85b7 and
254a477701.
That happens because struct v4l2_edid should be visible by both
subdev and V4L2 APIs. So, it was moved to v4l2-common.h.
As Linus pointed, the proper fix is to just add an include for
linux/types.h at v4l2-common.h.

but instead the widening contributor base. It is good to see that
interest is increasing in GFS2, and I'd like to thank all the
contributors to this patch set.
In addition to the usual set of bug fixes and clean ups, there are
patches to improve inode creation performance when xattrs are
required and some improvements to the transaction code which is
intended to help improve scalability after further changes in due
course.
Journal extent mapping is also updated to make it more efficient
and again, this is a foundation for future work in this area.
The maximum number of ACLs has been increased to 300 (for a 4k
block size) which means that even with a few additional xattrs
from selinux, everything should fit within a single fs block.
There is also a patch to bring GFS2's own copy of the writepages
code up to the same level as the core VFS. Eventually we may be
able to merge some of this code, since it is fairly similar.
The other major change this time, is bringing consistency to
the printing of messages via fs_<level>, pr_<level> macros.

Pull renameat2 system call from Miklos Szeredi:
"This adds a new syscall, renameat2(), which is the same as renameat()
but with a flags argument.
The purpose of extending rename is to add cross-rename, a symmetric
variant of rename, which exchanges the two files. This allows
interesting things, which were not possible before, for example
atomically replacing a directory tree with a symlink, etc... This
also allows overlayfs and friends to operate on whiteouts atomically.
Andy Lutomirski also suggested a "noreplace" flag, which disables the
overwriting behavior of rename.
These two flags, RENAME_EXCHANGE and RENAME_NOREPLACE are only
implemented for ext4 as an example and for testing"

reused.
- added a new SDR driver (rtl2832u_sdr)
- added a new tuner driver (msi001)
- several improvements at em28xx driver to fix PM support, device
removal and to split the V4L2 specific bits into a separate
sub-driver
- one driver got converted to videobuf2 (s2255drv)
- the e4000 tuner driver now follows an improved binding model
- some fixes at V4L2 compat32 code
- several fixes and enhancements at videobuf2 code

[ NOTE! This merge effective drops commit 4329b93b28 ("of: Reduce
indentation in of_graph_get_next_endpoint").
The of_graph_get_next_endpoint() function was moved and renamed by
commit fd9fdb78a9 ("[media] of: move graph helpers from
drivers/media/v4l2-core to drivers/of"). It was originally called
v4l2_of_get_next_endpoint() and lived in the file
drivers/media/v4l2-core/v4l2-of.c.
In that original location, it was then fixed to support empty port
nodes by commit b9db140c1e ("[media] v4l: of: Support empty port
nodes"), and that commit clashes badly with the dropped "Reduce
intendation" commit. I had to choose one or the other, and decided
that the "Support empty port nodes" commit was more important ]
