Rather than DRM_PANEL_LD9040 selecting SPI, which then results in an
increase in the probability of Kconf reporting circular dependencies
(we're one "select" away from that right now), make this depend on
SPI instead.  This is akin to having some driver select DRM.

Having some drivers depend on a subsystem, and other drivers select a
subsystem is a recipe for circular dependencies, and there's really no
need for it.

The potential circular dependency (which can be caused today by the
addition of selecting DRM_PANEL from DRM_IMX_LDB) is:

  symbol DMADEVICES is selected by SAMSUNG_DMADEV
  symbol SAMSUNG_DMADEV is selected by S3C64XX_PL080
  symbol S3C64XX_PL080 is selected by SPI_S3C64XX
  symbol SPI_S3C64XX depends on SPI
  symbol SPI is selected by DRM_PANEL_LD9040
  symbol DRM_PANEL_LD9040 depends on DRM_PANEL
  symbol DRM_PANEL is selected by DRM_IMX_LDB
  symbol DRM_IMX_LDB depends on MFD_SYSCON
  symbol MFD_SYSCON is selected by POWER_RESET_KEYSTONE
  symbol POWER_RESET_KEYSTONE depends on POWER_SUPPLY
  symbol POWER_SUPPLY is selected by HID_SONY
  symbol HID_SONY depends on NEW_LEDS
  symbol NEW_LEDS is selected by BACKLIGHT_ADP8860
  symbol BACKLIGHT_ADP8860 depends on BACKLIGHT_CLASS_DEVICE
  symbol BACKLIGHT_CLASS_DEVICE is selected by FB_MX3

When we mirror packets from a vxlan tunnel to other device,
the mirror device should see the same packets (that is, without
outer header). Because vxlan tunnel sets dev->hard_header_len,
tcf_mirred() resets mac header back to outer mac, the mirror device
actually sees packets with outer headers

Vxlan tunnel should set dev->needed_headroom instead of
dev->hard_header_len, like what other ip tunnels do. This fixes
the above problem.

This patch contains several fixes for Scsi START_STOP_UNIT. The previous
code did not account for signed vs. unsigned arithmetic which resulted
in an invalid lowest power state caculation when the device only supports
1 power state.

The code for Power Condition == 2 (Idle) was not following the spec. The
spec calls for setting the device to specific power states, depending
upon Power Condition Modifier, without accounting for the number of
power states supported by the device.

The code for Power Condition == 3 (Standby) was using a hard-coded '0'
which is replaced with the macro POWER_STATE_0.

There is a potential dead lock if a cpu event occurs during nvme probe
since it registered with hot cpu notification. This fixes the race by
having the module register with notification outside of probe rather
than have each device register.

The actual work is done in a scheduled work queue instead of in the
notifier since assigning IO queues has the potential to block if the
driver creates additional queues.

This patch fixes a NULL pointer dereference regression bug that was
introduced with:

commit 1e1110c4
Author: Mikulas Patocka <mpatocka@redhat.com>
Date:   Sat May 17 06:49:22 2014 -0400

    target: fix memory leak on XCOPY

Now that target_put_sess_cmd() -> kref_put_spinlock_irqsave() is
called with a valid se_cmd->cmd_kref, a NULL pointer dereference
is triggered because the XCOPY passthrough commands don't have
an associated se_session pointer.

To address this bug, go ahead and checking for a NULL se_sess pointer
within target_put_sess_cmd(), and call se_cmd->se_tfo->release_cmd()
to release the XCOPY's xcopy_pt_cmd memory.

- 82% improvement comparing with NO SG & TSO patch

Since imx6dl FEC Bandwidth is limited to SOC system bus bandwidth, the
performance with SW TSO is a milestone.

A malicious VF might try to starve the other VFs & PF by creating
contineous doorbell floods. In order to negate this, HW has a threshold of
doorbells per client, which will stop the client doorbells from arriving
if crossed.

The threshold currently configured for VFs is too low - under extreme traffic
scenarios, it's possible for a VF to reach the threshold and thus for its
fastpath to stop working.
