====================
bonding: introduce new option API

This patchset's goal is to introduce a new option API which should be used
to properly describe the bonding options with their mode dependcies and
requirements. With this patchset applied we get centralized option
manipulation, automatic RTNL acquire per option setting, automatic option
range checking, mode dependcy checking and other various flags which are
described in detail in patch 01's commit message and comments.
Also the parameter passing is changed to use a specialized structure which
is initialized to a value depending on the needs.
The main exported functions are:
 __bond_opt_set() - set an option (RTNL should be acquired prior)
 bond_opt_init(val|str) - init a bond_opt_value struct for value or string
                          parameter passing
 bond_opt_tryset_rtnl() - function which tries to acquire rtnl, mainly used
                          for sysfs
 bond_opt_parse - used to parse or check for valid values
 bond_opt_get - retrieve a pointer to bond_option struct for some option
 bond_opt_get_val - retrieve a pointer to a bond_opt_value struct for
                    some value

The same functions are used to set an option via sysfs and netlink, just
the parameter that's passed is usually initialized in a different way.
The converted options have multiple style fixes, there're some longer
lines but they looked either ugly or were strings/pr_warnings, if you
think some line would be better broken just let me know :-) there're
also a few sscanf false-positive warnings.
I decided to keep the "unsuppmodes" way of mode dep checking since it's
straight forward, if we make a more general way for checking dependencies
it'll be easy to change it.

Future plans for this work include:
 - Automatic sysfs generation from the bond_opts[].
 - Use of the API in bond_check_params() and thus cleaning it up (this has
   actually started, I'll take care of the rest in a separate patch)
 - Clean up all option-unrelated files of option definitions and functions

I've tried to leave as much documentation as possible, if there's anything
unclear please let me know. One more thing, I haven't moved all
option-related functions from bonding.h to the new bond_options.h, this
will be done in a separate patch, it's in my todo list.

This patchset has been tested by setting each converted option via sysfs
and netlink to a couple of wrong values, a couple of correct values and
some random values, also for the opts that have flags they have been
tested as well.

drm/nouveau: make vga_switcheroo code depend on VGA_SWITCHEROO

Commit 8116188fdef594 ("nouveau/acpi: hook up to the MXM method for mux
switching.") broke the build on non-x86 architectures due to the new
dependency on MXM and MXM being an x86 platform driver.

It built previously since the vga switcheroo registration routines were
zereod out on !X86.  The code was built in but unused.

This patch makes all of the DSM code depend on CONFIG_VGA_SWITCHEROO,
allowing it to build on non-x86 and shrinking the module size as well.

drm/cirrus: correct register values for 16bpp

When the mode is set with 16bpp on QEMU, the output gets totally broken.
The culprit is the bogus register values set for 16bpp, which was likely
copied from from a wrong place.

pnfs: Proper delay for NFS4ERR_RECALLCONFLICT in layout_get_done

An NFS4ERR_RECALLCONFLICT is returned by server from a GET_LAYOUT
only when a Server Sent a RECALL do to that GET_LAYOUT, or
the RECALL and GET_LAYOUT crossed on the wire.
In any way this means we want to wait at most until in-flight IO
is finished and the RECALL can be satisfied.

So a proper wait here is more like 1/10 of a second, not 15 seconds
like we have now. In case of a server bug we delay exponentially
longer on each retry.

Current code totally craps out performance of very large files on
most pnfs-objects layouts, because of how the map changes when the
file has grown into the next raid group.

[Stable: This will patch back to 3.9. If there are earlier still
 maintained trees, please tell me I'll send a patch]

af_packet: Add Queue mapping mode to af_packet fanout operation

This patch adds a queue mapping mode to the fanout operation of af_packet
sockets.  This allows user space af_packet users to better filter on flows
ingressing and egressing via a specific hardware queue, and avoids the potential
packet reordering that can occur when FANOUT_CPU is being used and irq affinity
varies.

Tested successfully by myself.  applies to net-next
