Include TipSwitch in the touch detection decision for some single touch
firmwares. Confidence and InRange are high for all finger events
including those used to indicate the finger is no longer in contact with
the sensor.

I squelched TipSwitch in a recent patch which resulted in the loss
of Touch events for single touch firmwares. This patch just puts Touch back
in for single touch, and bundles it with DoubleTap (like the multitouch code).
The two events are used to convey the same message to different drivers.

Commit 6549981bc54777c ("HID: fix N-trig touch panel with recent firmware")
adds a quirk that is needed for devices with more recent firmware so that
they become operational.
As it's not directly obvious from the code why is it needed, a comment
is worthwile.

Some BIOSes don't configure HPA during boot but do so while resuming.
This causes harddrives to shrink during resume making libata detach
and reattach them. This can be worked around by unlocking HPA if old
size equals native size.
Add ATA_DFLAG_UNLOCK_HPA so that HPA unlocking can be controlled
per-device and update ata_dev_revalidate() such that it sets
ATA_DFLAG_UNLOCK_HPA and fails with -EIO when the above condition is
detected.
This patch fixes the following bug.

Crucial said,
Thank you for contacting us. We know that with our M225 line of SSDs
you sometimes need to disable NCQ (native command queuing) to avoid
just the type of errors you're seeing. Our recommendation for the
M225 is to add libata.force=noncq to your Linux kernel boot options,
under the kernel ATA library option.
I have sent your feedback to the engineers working on the C300, and
asked them to please pass it on to the firmware team. I have been
notified that they are in the process of testing and finalizing a
new firmware version, that you can expect to see released around the
end of April. We’ll keep you posted as to when it will be available
for download.
So, turn off NCQ on the drive w/ the current firmware revision.

Module refcounting is implemented with a per-cpu counter for speed.
However there is a race when tallying the counter where a reference may
be taken by one CPU and released by another. Reference count summation
may then see the decrement without having seen the previous increment,
leading to lower than expected count. A module which never has its
actual reference drop below 1 may return a reference count of 0 due to
this race.
Module removal generally runs under stop_machine, which prevents this
race causing bugs due to removal of in-use modules. However there are
other real bugs in module.c code and driver code (module_refcount is
exported) where the callers do not run under stop_machine.
Fix this by maintaining running per-cpu counters for the number of
module refcount increments and the number of refcount decrements. The
increments are tallied after the decrements, so any decrement seen will
always have its corresponding increment counted. The final refcount is
the difference of the total increments and decrements, preventing a
low-refcount from being returned.

There have been a number of reports of people seeing the message:
"name_count maxed, losing inode data: dev=00:05, inode=3185"
in dmesg. These usually lead to people reporting problems to the filesystem
group who are in turn clueless what they mean.
Eventually someone finds me and I explain what is going on and that
these come from the audit system. The basics of the problem is that the
audit subsystem never expects a single syscall to 'interact' (for some
wish washy meaning of interact) with more than 20 inodes. But in fact
some operations like loading kernel modules can cause changes to lots of
inodes in debugfs.
There are a couple real fixes being bandied about including removing the
fixed compile time limit of 20 or not auditing changes in debugfs (or
both) but neither are small and obvious so I am not sending them for
immediate inclusion (I hope Al forwards a real solution next devel
window).
In the meantime this patch simply adds 'audit' to the beginning of the
crap message so if a user sees it, they come blame me first and we can
talk about what it means and make sure we understand all of the reasons
it can happen and make sure this gets solved correctly in the long run.

setup_leaf_for_split needs to drop the path and search again, and has
checks to see if the item we want to split changed size. But, it misses
the case where the leaf changed and now has enough room for the item
we want to insert.
This adds an extra check to make sure the leaf really needs splitting
before we call btrfs_split_leaf(), which keeps us from trying to split
a leaf with a single item.
btrfs_split_leaf() will blindly split the single item leaf, leaving us
with one good leaf and one empty leaf and then a crash.

This creates the reference to a new snapshot in the same commit as the
snapshot itself. This avoids the need for a second commit in order for a
snapshot to be persistent, and also avoids the problem of "leaking" a
new snapshot tree root if the host crashes before the second commit takes
place.
It is not at all clear to me why it wasn't always done this way. If there
is still a reason for the two-stage {create,finish}_pending_snapshots()
approach I'm missing something! :)
I've been running this for a couple weeks under pretty heavy usage (a few
snapshots per minute) without obvious problems.

Everytime we start a new flushing thread, we init the waitqueue if there isn't a
flushing thread running. The problem with this is we check
space_info->flushing, which we clear right before doing a wake_up on the
flushing waitqueue, which causes problems if we init the waitqueue in the middle
of clearing the flushing flagh and calling wake_up. This is hard to hit, but
the code is wrong anyway, so init the flushing/allocating waitqueue when
creating the space info and let it be. I haven't seen the panic since I've been
using this patch. Thanks,

Pagecache pages should be allocated with __page_cache_alloc, so they
obey pagecache memory policies.
add_to_page_cache_lru is exported, so it should be used. Benefits over
using a private pagevec: neater code, 128 bytes fewer stack used, percpu
lru ordering is preserved, and finally don't need to flush pagevec
before returning so batching may be shared with other LRU insertions.

In initial design, walk_page_range() was designed just for walking page
table and it didn't require mmap_sem. Now, find_vma() etc.. are used
in walk_page_range() and we need mmap_sem around it.
This patch adds mmap_sem around walk_page_range().
Because /proc/<pid>/pagemap's callback routine use put_user(), we have
to get rid of it to do sane fix.
