While doing testing, there are failures as MPA Reject call is not
handled.  To handle MPA Reject call, following changes are done:

*Handle inbound/outbound MPA Reject response message.
	When nes_reject() is called for pending MPA request reply,
	send the MPA Reject message to its peer (active
	side)cm_node. The peer cm_node (active side) will indicate
	Reject message event for the pending Connect Request.

*Handle MPA Reject response message for loopback connections and listener.
	When MPA Request is rejected, check if it is a loopback
	connection and if it is then it will send Reject message event
	to its peer loopback node. Also when destroying listener,
	check if the cm_nodes for that listener are loopback or not.

*Add gracefull connection close with the MPA Reject response message.
	Send gracefull close (FIN, FIN ACK..) to terminate the cm_nodes.

*Some code re-org while making the above changes.
	Removed recv_list and recv_list_lock from the cm_node
	structure as there can be only one receive close entry on the
	timer. Also implemented handle_recv_entry() as receive close
	entry is processed from both nes_rem_ref_cm_node() as well as
	nes_cm_timer_tick().

Two level 256 byte PBLs was not implemented so the driver could report
out of memory when in fact there were PBLs still available.

This solution prefers to use 4KB PBLs over two level 256B PBLs until
the number of 4KB PBLs falls below a threshold.  At this point the 4KB
PBL structure is converted to use 256B PBLs which prevents the driver
from running out of 4KB PBLs too quickly.

NETIF_F_LLTX is deprecated. Remove private TX locking from the driver
and remove the NETIF_F_LLTX feature flag.  This also fixes a warning
in some configs that comes from doing skb_linearize() call in the
hard_start_xmit method with IRQs disabled (if HIGHMEM is enabled,
skb_linearize() may end up enabling BHs, which is a no-no if hard IRQs
are disabled in that context).  By getting rid of LLTX, we do not
disable IRQs when skb_linearize() is called.

Remove the sq_lock as it is not needed for non-LLTX.  Fix ethtool not
to show the counter for sq_lock.

A pointer to wm8400_regulator_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

The current work request posting code writes the LSO segment before
writing any data segments.  This leaves a window where the LSO segment
overwrites the stamping in one cacheline that the HCA prefetches
before the rest of the cacheline is filled with the correct data
segments.  When the HCA processes this work request, a local
protection error may result.

Fix this by saving the LSO header size field off and writing it only
after all data segments are written.  This fix is a cleaned-up version
of a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>.

  Btrfs: fix ioctl arg size (userland incompatible change!)
  Btrfs: Clear the device->running_pending flag before bailing on congestion

The structure used to send device in btrfs ioctl calls was not
properly aligned, and so 32 bit ioctls would not work properly on
64 bit kernels.

We could fix this with compat ioctls, but we're just one byte away
and it doesn't make sense at this stage to carry about the compat ioctls
forever at this stage in the project.

This patch brings the ioctl arg up to an evenly aligned 4k.
Signed-off-by: Chris Mason <chris.mason@oracle.com>

Btrfs maintains a queue of async bio submissions so the checksumming
threads don't have to wait on get_request_wait.  In order to avoid
extra wakeups, this code has a running_pending flag that is used
to tell new submissions they don't need to wake the thread.

When the threads notice congestion on a single device, they
may decide to requeue the job and move on to other devices.  This
makes sure the running_pending flag is cleared before the
job is requeued.

It should help avoid IO stalls by making sure the task is woken up
when new submissions come in.
