This patch makes socketpair() use error paths which do not
rely on heavy-weight call to sys_close(): it's better to try
to push the file descriptor to userspace before installing
the socket file to the file descriptor, so that errors are
catched earlier and being easier to handle.

Using sys_close() seems to be the exception, while writing the
file descriptor before installing it look like it's more or less
the norm: eg. except for code used in init/, error handling
involve fput() and put_unused_fd(), but not sys_close().

This make socketpair() usage of sys_close() quite unusual.
So it deserves to be replaced by the common pattern relying on
fput() and put_unused_fd() just like, for example, the one used
in pipe(2) or recvmsg(2).

Three distinct error paths are still needed since calling
fput() on file structure returned by sock_alloc_file() will
implicitly call sock_release() on the associated socket
structure.

Intel Wired LAN Driver Updates

This series contains updates to i40e, igb, ixgbe and ixgbevf.

Shannon provides a couple of i40e patches, first restricts the ethtool
diag test messages by using netif_info() macro to when the hardware
bit is enabled in the message level netdev message mask.  Second
provides a fix for when there is an out-of-range descriptor request.

Kamil provides a fix for i40e by updating the loopback enum types and
add information about the current loopback mode to data returned from
get_link_info().

Jesse provides a fix for i40e define name that was being mis-used.
I40E_ITR_NONE was being used as an ITRN register index by accident
because it was easily associated with the i40e Rx ITR and friends
defines, when it should be associated with the DYN_CTL register sets.

Jacob provides an update for ixgbevf Kconfig description since the VF
driver supports more than just the 82599 device.

Don and Alex provide a cleanup patch for ixgbe to make it where head,
tail, next to clean and next to use are all reset in a single function
for both Tx and Rx path.  Before, the code for this was spread out over
several areas which made it difficult to track what the values were for
each of the values.

Carolyn provides two igb patches to add a media switching feature for
i354 PHY's and new Media Auto Sense for 82580 devices only.

Aaron Sierra provides a fix for igb to resolve an issue with the 64-bit
PCI addresses being truncated because the return values of
pci_resource_start() and pci_resouce_end() were being cast to unsigned
long.

Guenter Roeck provides two igb patches, first simplifies the code by
attaching the hwmon sysfs attributes to hwmon device instead of the
PCI device.  Second fixes the temperature sensor attribute index by
setting it to 1 instead of 0 (per hwmon ABI).

Simplify the code. Attach hwmon sysfs attributes to hwmon device
instead of pci device. Avoid race conditions caused by attributes
being created after registration and provide mandatory 'name'
attribute by using new hwmon API.

Other cleanup:

Instead of allocating memory for hwmon attributes, move attributes
and all other hwmon related data into struct hwmon_buff and allocate
the entire structure using devm_kzalloc.

Check return value from calls to igb_add_hwmon_attr() one by one instead
of logically combining them all together.

Commit f4ec9e95 "mlx4_core: Change bitmap allocator to work in round-robin fashion"
introduced round-robin allocation (via bitmap) for all resources which allocate
via a bitmap.

Round robin allocation is desirable for mcgs, counters, pd's, UARs, and xrcds.
These are simply numbers, with no involvement of ICM memory mapping.

Round robin is required for QPs, since we had a problem with immediate
reuse of a 24-bit QP number (commit f4ec9e95).

However, for other resources which use the bitmap allocator and involve
mapping ICM memory -- MPTs, CQs, SRQs -- round-robin is not desirable.

What happens in these cases is the following:

ICM memory is allocated and mapped in chunks of 256K.

Since the resource allocation index goes up monotonically, the allocator
will eventually require mapping a new chunk. Now, chunks are also unmapped
when their reference count goes back to zero.  Thus, if a single app is
running and starts/exits frequently we will have the following situation:

When the app starts, a new chunk must be allocated and mapped.

When the app exits, the chunk reference count goes back to zero, and the
chunk is unmapped and freed. Therefore, the app must pay the cost of allocation
and mapping of ICM memory each time it runs (although the price is paid only when
allocating the initial entry in the new chunk).

For apps which allocate MPTs/SRQs/CQs and which operate as described above,
this presented a performance problem.

We therefore roll back the round-robin allocator modification for MPTs, CQs, SRQs.
