 	Add new hash for balance-xor and 802.3ad modes.  Originally
 submitted by "Glenn Griffin" <ggriffin.kernel@gmail.com>; modified by
 Jay Vosburgh to move setting of hash policy out of line, tweak the
 documentation update and add version update to 3.2.2.

	Glenn's original comment follows:

Included is a patch for a new xmit_hash_policy for the bonding driver
that selects slaves based on MAC and IP information.  This is a middle
ground between what currently exists in the layer2 only policy and the
layer3+4 policy.  This policy strives to be fully 802.3ad compliant by
transmitting every packet of any particular flow over the same link.
As documented the layer3+4 policy is not fully compliant for extreme
cases such as ip fragmentation, so this policy is a nice compromise
for environments that require full compliance but desire more than the
layer2 only policy.

The previous code returned '\n' (that is, a single empty line)
from most files, with one exception (xmit_hash_policy), where
it returned 'NA\n'.  This patch consolidates each file to return
nothing at all if not applicable, not even a '\n'.

I find this behaviour more usual, more useful, more efficient
and shorter to code from both sides.

Also remove trailing spaces from multivalued files.

This fixes output like for example:

$ od -c /sys/class/net/bond0/bonding/slaves
0000000   e   t   h   -   l   e   f   t       e   t   h   -   r   i   g
0000020   h   t      \n  \0
0000025

It mostly entails deleting '+1'-s after sprintf() calls: the return value
of sprintf is the number of characters printed, without the closing NUL,
ie. exactly what the sysfs interface requires.  The three multivalue
cases are different, because they also have to swallow back a trailing
space.

The AMD CS5535/CS5536 GPIO has two alternate output modes: AUX-1 and AUX-2.
When either AUX is enabled, the cs5535_gpio driver cannot control the
output.

Some BIOS code for the Geode processor enables AUX-1 for GPIO-1, which
configures it as the PC BEEP output.

This patch will disable AUX-1 and AUX-2 when the user enables output.

Fix SPI driver to work with SPI flash ST M25P16 on bf548

Currently the SPI driver enables the SPI controller and sets the SPI baud
register for each SPI transfer.  But they should never be changed within a SPI
message session, in which several SPI transfers are pumped.

This patch moves SPI setting to the begining of a message session, and
never disables SPI controller until an error occurs.
