a8ba8bffbe Staging: p9auth: a few fixes
1. The memory into which we copy 'u1@u2' needs space for u1, @,
	u2, and a final \0 which strcat copies in.
2. Strsep changes the value of its first argument.  So use a
	temporary variable to pass to it, so we pass the original
	value to kfree!
3. Allocate an extra char to user_buf, because we need a trailing \0
	since we later kstrdup it.

I am about to send out an LTP testcase for this driver, but
in addition the correctness of the hashing can be verified as
follows:

 #include <stdio.h>
 #include <stdlib.h>
 #include <unistd.h>

int main(int argc, char *argv[])
{
        char in[41], out[20];
        unsigned int v;
        int i, ret;

        ret = read(STDIN_FILENO, in, 40);
        if (ret != 40)
                exit(1);
        in[40] = '\0';
        for (i = 0; i < 20; i++) {
                sscanf(&in[2*i], "%02x", &v);
                out[i] = v;
        }
        write(STDOUT_FILENO, out, 20);
}

as root, to test userid 501 switching to uid 0, choosing
'random' string 'ab':

echo -n "501@0" > plain
openssl sha1  -hmac 'ab' plain |awk '{ print $2 '} > dgst
./unhex < dgst > dgst.u
mknod /dev/caphash 504 0
mknod /dev/capuse 504 1
chmod ugo+w /dev/capuse
cat dgst.u > /dev/caphash

as uid 501,
echo "501@0@ab" > /dev/capuse
id -u  # should now show 0.

This patch adds a prepare_multicast callback for the winbond driver

This also fixes incompatible pointer assignment build errors because
->configure_filter had changed.

This is build tested only, but that's more than the original code received.

The author has found a number of problems with the current version

the driver now and add it back in a future kernel release.

cc9b0b9bea IRQ: Change __softirq_pending to unsigned int in asm-generic/hardirq.h.
Since the beginnings in aafe4dbed0
("asm-generic: add generic versions of common headers") the generic
version of <asm/hardirq.h> defined __softirq_pending as unsigned long.

Which is different from other architectures for no apparent good reason
and was causing the following warning:

  kernel/time/tick-sched.c: In function 'tick_nohz_stop_sched_tick':
  kernel/time/tick-sched.c:261: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'long unsigned int'

On newer ASUS boards (e.g. P7P55D) the EC (that - among other things - is
responsible for updating the readings from the hwmon sensors) is disabled
by default since ASUS detected conflict with some tools under Windows.
The following patch checks the state of the EC and enable it if needed;
under Linux, native drivers are locked out from ACPI owned resources so
there's no risk of conflict.

ac6889cbb2 Btrfs: fix file clone ioctl for bookend extents
The file clone ioctl was incorrectly taking the offset into the
extent on disk into account when calculating the length of the
cloned extent.

The length never changes based on the offset into the physical extent.

Test case:

fallocate -l 1g image
mke2fs image
bcp image image2
e2fsck -f image2

(errors on image2)

The math bug ends up wrapping the length of the extent, and things
go wrong from there.

e9061e2148 Btrfs: fix uninit compiler warning in cow_file_range_nocow
The extent_type variable was exposed uninit via a goto.  It should be
impossible to trigger because it is protected by a check on another
variable, but this makes sure.

b690081d4d perf_events: Add event constraints support for Intel processors
On some Intel processors, not all events can be measured in all
counters. Some events can only be measured in one particular
counter, for instance. Assigning an event to the wrong counter does
not crash the machine but this yields bogus counts, i.e., silent
error.

This patch changes the event to counter assignment logic to take
into account event constraints for Intel P6, Core and Nehalem
processors. There is no contraints on Intel Atom. There are
constraints on Intel Yonah (Core Duo) but they are not provided in
this patch given that this processor is not yet supported by
perf_events.

As a result of the constraints, it is possible for some event
groups to never actually be loaded onto the PMU if they contain two
events which can only be measured on a single counter. That
situation can be detected with the scaling information extracted
with read().

04a705df47 perf_events: Check for filters on fixed counter events
Intel fixed counters do not support all the filters possible with a
generic counter. Thus, if a fixed counter event is passed but with
certain filters set, then the fixed_mode_idx() function must fail
and the event must be measured in a generic counter instead.

Reject filters are: inv, edge, cnt-mask.

efefb1438b Btrfs: remove negative dentry when deleting subvolumne
The use of btrfs_dentry_delete is removing dentries from the
dcache when deleting subvolumne. btrfs_dentry_delete ignores
negative dentries. This is incorrect since if we don't remove
the negative dentry, its parent dentry can't be removed.

a2767cfb1d sh: Don't allocate smaller sized mappings on every iteration
Currently, we've got the less than ideal situation where if we need to
allocate a 256MB mapping we'll allocate four entries like so,

	 entry 1: 128MB
	 entry 2:  64MB
	 entry 3:  16MB
	 entry 4:  16MB

This is because as we execute the loop in pmb_remap() we will
progressively try mapping the remaining address space with smaller and
smaller sizes. This isn't good because the size we use on one iteration
may be the perfect size to use on the next iteration, for instance when
the initial size is divisible by one of the PMB mapping sizes.

With this patch, we now only need two entries in the PMB to map 256MB of
address space,

	  entry 1: 128MB
	  entry 2: 128MB
