Jarod Wilson ba6a078b77 Input: add KEY_IMAGES specifically for AL Image Browser
Many media center remotes have buttons intended for jumping straight to
one type of media browser or another -- commonly, images/photos/pictures,
audio/music, television, and movies. At present, remotes with an images
or photos or pictures button use any number of different keycodes which
sort of maybe fit. I've seen at least KEY_MEDIA, KEY_CAMERA,
KEY_GRAPHICSEDITOR and KEY_PRESENTATION. None of those seem quite right.
In my mind, KEY_MEDIA should be something more like a media center
application launcher (and I'd like to standardize on that for things
like the windows media center button on the mce remotes). KEY_CAMERA is
used in a lot of webcams, and typically means "take a picture now".
KEY_GRAPHICSEDITOR implies an editor, not a browser. KEY_PRESENTATION
might be the closest fit here, if you think "photo slide show", but it
may well be more intended for "run application in full-screen
presentation mode" or to launch something like magicpoint, I dunno.
And thus, I'd like to have a KEY_IMAGES, which matches the HID Usage AL
Image Browser, the meaning of which I think is crystal-clear. I believe
AL Audio Browser is already covered by KEY_AUDIO, and AL Movie Browser
by KEY_VIDEO, so I'm also adding appropriate comments next to those
keys.

Chris Mason 109b36a2bb Btrfs: make uncache_state unconditional
The extent_io code can take cached pointers into the extent state trees,
and these can make lookups much faster in common operations.  The
caching only happens when specific bits are set that prevent merging
and splitting of the extent state.

A help function was added to uncache the state, and it was testing
the same set of conditionals.  This can leak in very strange corner
cases where the lock bit goes away unexpectedly.

The uncaching should be unconditional.  Once we have a ref on the
extent we should always give it up.

nfs_scan_commit() is called with the inode->i_lock held, but it then
calls __mark_inode_dirty() while still holding the lock. This causes
a deadlock.

Push the inode->i_lock into nfs_scan_commit() so it can protect only
the parts of the code it needs to and can be dropped before the call
to __mark_inode_dirty() to avoid the deadlock.

Linus Torvalds 95042f9eb7 vm: fix mlock() on stack guard page
Commit 53a7706d5e ("mlock: do not hold mmap_sem for extended periods
of time") changed mlock() to care about the exact number of pages that
__get_user_pages() had brought it.  Before, it would only care about
errors.

And that doesn't work, because we also handled one page specially in
__mlock_vma_pages_range(), namely the stack guard page.  So when that
case was handled, the number of pages that the function returned was off
by one.  In particular, it could be zero, and then the caller would end
up not making any progress at all.

Rather than try to fix up that off-by-one error for the mlock case
specially, this just moves the logic to handle the stack guard page
into__get_user_pages() itself, thus making all the counts come out
right automatically.

Linus Torvalds be85bccaa5 Revert "vfs: Export file system uuid via /proc/<pid>/mountinfo"
This reverts commit 93f1c20bc8.

It turns out that libmount misparses it because it adds a '-' character
in the uuid string, which libmount then incorrectly confuses with the
separator string (" - ") at the end of all the optional arguments.

Upstream libmount (in the util-linux tree) has been fixed, but until
that fix actually percolates up to users, we'd better not expose this
change in the kernel.

Let's revisit this later (possibly by exposing the UUID without any '-'
characters in it, avoiding the user-space bug).

My X201s BIOS version string is 6QET46V1 (1.16 ). The
EC version string is 6QHT28WW-1.09. The driver was requiring that both
of these have 'WW' in positions 6 and 7. I don't know what the
significance of having 'V1' there instead is, but removing the test
makes the driver load on my machine.

Jeff Layton ca83ce3d5b cifs: don't allow mmap'ed pages to be dirtied while under writeback (try #3)
This is more or less the same patch as before, but with some merge
conflicts fixed up.

If a process has a dirty page mapped into its page tables, then it has
the ability to change it while the client is trying to write the data
out to the server. If that happens after the signature has been
calculated then that signature will then be wrong, and the server will
likely reset the TCP connection.

This patch adds a page_mkwrite handler for CIFS that simply takes the
page lock. Because the page lock is held over the life of writepage and
writepages, this prevents the page from becoming writeable until
the write call has completed.

With this, we can also remove the "sign_zero_copy" module option and
always inline the pages when writing.

Jens Axboe f4af3c3d07 block: move queue run on unplug to kblockd
There are worries that we are now consuming a lot more stack in
some cases, since we potentially call into IO dispatch from
schedule() or io_schedule(). We can reduce this problem by moving
the running of the queue to kblockd, like the old plugging scheme
did as well.

This may or may not be a good idea from a performance perspective,
depending on how many tasks have queue plugs running at the same
time. For even the slightly contended case, doing just a single
queue run from kblockd instead of multiple runs directly from the
unpluggers will be faster.

The CPU_FTRS_POSSIBLE and CPU_FTRS_ALWAYS defines did not encompass
e5500 CPU features when built for 64-bit.  This causes issues with
cpu_has_feature() as it utilizes the POSSIBLE & ALWAYS defines as part
of its check.

Create a unique CPU_FTRS_E5500 (as its different from CPU_FTRS_E500MC),
created a new group for 64-bit Book3e based CPUs and add CPU_FTRS_E5500
to that group.

Prabhakar Kushwaha 07d9fce24d powerpc: Check device status before adding serial device
serial port nodes with the property status="disabled" are not usable and so
avoid adding "disabled" port with the system.

Samuel Ortiz e710d7d5a9 mfd: Fetch cell pointer from platform_device->mfd_cell
In order for MFD drivers to fetch their cell pointer but also their
platform data one, an mfd cell pointer is added to the platform_device
structure.
That allows all MFD sub devices drivers to be MFD agnostic, unless
they really need to access their MFD cell data. Most of them don't,
especially the ones for IPs used by both MFD and non MFD SoCs.

Jens Axboe cf82c79839 block: kill queue_sync_plugs()
The original use for this dates back to when we had to track write
requests for serializing around barriers. That's not needed anymore,
so kill it.

Jens Axboe dc6d36c971 block: readd plug trace event
This was removed with the queue plug state. But we can easily readd
by checking if this is the first request going to this queue. It's
good information to have when tracing to see how effective the
plugging is.
