Currently there is hard-coding at various places in FAT for using
the SECTOR size alignment. So, In order to remove the hard coding
we need to change the usage of '9' in FAT code.

Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git for-linus
or
master.kernel.org:/pub/scm/linux/kernel/git/dtor/input.git for-linus
to receive updates for the input subsystem. Just a few driver fixes.

There is lots of places that perform:

while (op != &ftrace_list_end) {
Add a helper macro to do this, and also optimize for a single
entity. That is, gcc will optimize a loop for either no iterations

Using context bit recursion checking, we can help increase the
performance of the ring buffer.

Convert the bits into enums which makes the code a little easier

The function tracer had two different versions of function tracing.
The disabling of irqs version and the preempt disable version.
As function tracing in very intrusive and can cause nasty recursion
issues, it has its own recursion protection. But the old method to

From: Steven Rostedt
Currently for recursion checking in the function tracer, ftrace
tests a task_struct bit to determine if the function tracer had
recursed or not. If it has, then it will will return without going
further.
But this leads to races. If an interrupt came in after the bit
was set,
A couple of months ago I was playing with getting recursion
fixed with the function tracer. There's a lot of places that could
use improvements, and I also found a few cases where the recursion
protection would have false positives causing missed function tracing.
I implemented a per context bit c

The function tracing recursion self test should not crash
the machine if the resursion test fails. If it detects that
the function tracing is recursing when it should not be, then
bail, don't go into an infinite recursive loop.

If one of the function tracers set by the global ops is not recursion
safe, it can still be called directly without the added recursion
supplied by the ftrace infrastructure.

This patch adds detection for the Sweex LW323 USB wireless network card
in the rt2x00 driver (just one line in rt2800usb.c).
It applies to linux-3.7-rc3.

On a separate note, I want to thank everyone that helped with this
issue, especially Eric and Thomas, to and Steven and Thomas for
schooling me on the changelog extraction. This problem was a big one
for us that we were struggling to understand. All the help is greatly
appreciated.

Hello Linus,
This series is a second round of target fixes for v3.7-rc4 that have
come into target-devel over the last days, and are important enough to
be applied ASAP. Please go ahead and pull from:

Recently, I had re-sent a few patches. You have applied all the patches except
the balloon driver
