The Comedi "comedi_isadma.h" header is included by the source for the
"comedi_isadma" helper module and other modules that use it. It does
not compile cleanly when it is the first header file included. It uses
the `dma_addr_t` type, so include <linux/types.h> to declare it. (Also,
that indirectly takes care of the use of `NULL`.) It uses `struct
comedi_device *` in various function prototypes, so add an incomplete
declaration of `struct comedi_device`.

The Comedi "8255" module is both a standalone Comedi device driver
module for simple devices with one or more 8255 "Programmable Peripheral
Interface" chips at known I/O base addresses (configured at run-time),
and a helper module to configure a 8255-based digital I/O subdevice for
other Comedi drivers.
Split the "8255 subdevice helper" functionality into a new module:
"comedi_8255", leaving the standalone 8255 Comedi driver in the "8255"
module.
The Comedi "detach" routine of the standalone "8255" driver needs to
retrieve the I/O base address passed to the "comedi_8255" module to set
up each subdevice in order to release the I/O port regions it requested
in its "attach" routine. The "comedi_8255" module stores it in a
"subdevice private" data structure that is no longer known to the "8255"
module, so add a new, exported function `subdev_8255_regbase()` to
retrieve it.

Several Comedi driver modules call `subdev_8255_init()` or
`subdev_8255_mm_init()` to set up a digital I/O subdevice based on the
"8255" chip. One of the parameters to these functions is an optional
pointer to an I/O callback function to perform the actual register
accesses (an internal default callback function is used if NULL).
The kerneldoc for `subdev_8255_init()` and `subdev_8255_mm_init()`
describe the prototype of the optional I/O callback function
incorrectly (my fault), adding a non-existent parameter of type `struct
comedi_subdevice *`. Fix the kerneldoc. Also add parameter names to
the callback function pointer type wherever it occurs to make the usage
clearer.

The Comedi "8255" driver does not clean up properly on failure. It can
leave requested I/O port regions unreleased. Specifically, the Comedi
"attach" handler (`dev_8255_attach()`) requests a specified I/O port
region before calling `subdev_8255_init()` to set up the subdevice. If
that fails, the "attach" handler returns an error and the Comedi core
will call the "detach" handler (`dev_8255_detach()`) to clean up. The
"detach" handler is responsible for releasing the I/O port regions
successfully requested by the "attach" handler. Unfortunately, it is
unable to obtain the base address of the region if the call to
`subdev_8255_init()` failed.
Fix the I/O region leak by releasing the region in the "attach" handler
directly if the call to `subdev_8255_init()` fails.

instead of passing pointers to it around.
This fixes a regression introduced for v4.1-rc1 with commit 9ac8928e6,
where configfs_depend_item() callers using se_tpg_tfo->tf_subsys would

A recent patch to simplify the lustre large memory allocation
causes new warnings as an unintended side-effect:
lustre/lov/lov_request.c: In function 'lov_finish_set':
lustre/lov/lov_request.c:78:7: warning: unused variable 'len' [-Wunused-variable]
int len = set->set_oabufs * sizeof(*set->set_pga);
^
lustre/obdclass/acl.c: In function 'lustre_ext_acl_xattr_reduce_space':
lustre/obdclass/acl.c:123:6: warning: unused variable 'old_size' [-Wunused-variable]
int old_size = CFS_ACL_XATTR_SIZE(old_count, ext_acl_xattr);
^
The reason is that the 'size' argument to OBD_FREE_LARGE()
is never needed, which was previously hidden by the extra
abstractions.
This avoids the warnings by adding a cast to void, to tell
the compiler that the argument is intentionally unused.
A better fix is probably to remove the entire set of allocation
macros and open-code the normal kernel interface calls.

The current algorithm for deciding on the number of VRSS channels is
not optimal since we open up the min of number of CPUs online and the
number of VRSS channels the host is offering. So on a 32 VCPU guest
we could potentially open 32 VRSS subchannels. Experimentation has
shown that it is best to limit the number of VRSS channels to the number
of CPUs within a NUMA node.
Here is the new algorithm for deciding on the number of sub-channels we
would open up:
1) Pick the minimum of what the host is offering and what the driver
in the guest is specifying as the default value.
2) Pick the minimum of (1) and the numbers of CPUs in the NUMA
node the primary channel is bound to.

Add support for QCA IPQ806x Ethernet GMAC controller
This patch set adds support for the integrated Ethernet GMAC controller
on QCA IPQ806x SoC. This controller is based on a Gigabit Synopsys
DesignWare IP, already supported in the stmmac driver located in
drivers/net/ethernet/stmicro/stmmac.
This change is done as a follow-up to the following thread:
*http://www.spinics.net/lists/netdev/msg311265.html
While previous attempt was creating a new driver to drive this controller,
this new post leverages the existing stmmac driver by implementing the
SoC specific glue to it.
Aside from the pure stmmac glue layer, we have a couple of related
patches:
*IPQ806x NSS clock addition is cherry-picked and refreshed from the
following thread: https://lkml.org/lkml/2014/8/6/390
*phy-handle and fixed-link support are also added in this change set so the
driver can be fully functional on platforms using device-trees as well as
ethernet switches.

*Fix MODULE_LICENSE to "Dual BSD/GPL" as the dwmac-ipq806x.c is using
ISC license.
