If the interface is closed, but VFs exist, current code will spam all
the VFs with link messages every second. This is because the link event
code was looking at netif_carrier_ok() without checking to see if the
interface was actually open.

Refactor the logic to only check the carrier state if the interface is
actually open. This allows link changes to be reported correctly without
spamming the VFs.

When we receive an admin queue message, the msg_size field in the event
struct gets overwritten. Because of this, we need to reinit the field
each time we go through the loop. Without this we may receive truncated
messages due to the firmware thinking we have insufficient buffer size.

Pull ACPI and power management fixes from Rafael Wysocki:
 "These are fixes received after my previous pull request plus one that
  has been in the works for quite a while, but its previous version
  caused problems to happen, so it's been deferred till now.

  Fixed are two recent regressions (MFD enumeration and cpufreq-dt),
  ACPI EC regression introduced in 3.17, system suspend error code path
  regression introduced in 3.15, an older bug related to recovery from
  failing resume from hibernation and a cpufreq-dt driver issue related
  to operation performance points.

  Specifics:

   - Fix a crash on r8a7791/koelsch during resume from system suspend
     caused by a recent cpufreq-dt commit (Geert Uytterhoeven).

   - Fix an MFD enumeration problem introduced by a recent commit adding
     ACPI support to the MFD subsystem that exposed a weakness in the
     ACPI core causing ACPI enumeration to be applied to all devices
     associated with one ACPI companion object, although it should be
     used for one of them only (Mika Westerberg).

   - Fix an ACPI EC regression introduced during the 3.17 cycle causing
     some Samsung laptops to misbehave as a result of a workaround
     targeted at some Acer machines.  That includes a revert of a commit
     that went too far and a quirk for the Acer machines in question.
     From Lv Zheng.

   - Fix a regression in the system suspend error code path introduced
     during the 3.15 cycle that causes it to fail to take errors from
     asychronous execution of "late" suspend callbacks into account
     (Imre Deak).

   - Fix a long-standing bug in the hibernation resume error code path
     that fails to roll back everything correcty on "freeze" callback
     errors and leaves some devices in a "suspended" state causing more
     breakage to happen subsequently (Imre Deak).

   - Make the cpufreq-dt driver disable operation performance points
     that are not supported by the VR connected to the CPU voltage plane
     with acceptable tolerance instead of constantly failing voltage
     scaling later on (Lucas Stach)"

Pull PCI fixes from Bjorn Helgaas:
 "These changes, intended for v3.18, fix:

  Sysfs
    - Fix "enable" filename change (Greg Kroah-Hartman)

      An unintentional sysfs filename change in commit 5136b2da
      ("PCI: convert bus code to use dev_groups"), which appeared in
      v3.13, changed "enable" to "enabled", and this changes it back.

      Old users of "enable" are currently broken and will be helped by
      this change.  Anything that started to use "enabled" after v3.13
      will be broken by this change.  If necessary, we can add a symlink
      to make both work, but this patch doesn't do that.

  PCI device hotplug

      A mistaken duplicate merge that added a check twice.  Nothing's
      broken; this just removes the unnecessary code.

  Freescale i.MX6

  Revert duplicate "PCI: pciehp: Prevent NULL dereference during probe"

Rusty noticed a Really Bad Bug (tm) in my NT fix.  The entry code
reads out of bounds, causing the NT fix to be unreliable.  But, and
this is much, much worse, if your stack is somehow just below the
top of the direct map (or a hole), you read out of bounds and crash.

Excerpt from the crash:

[    1.129513] RSP: 0018:ffff88001da4bf88  EFLAGS: 00010296

  2b:*    f7 84 24 90 00 00 00     testl  $0x4000,0x90(%rsp)

That read is deterministically above the top of the stack.  I
thought I even single-stepped through this code when I wrote it to
check the offset, but I clearly screwed it up.

The cpsw driver did not support the IFF_ALLMULTI flag which makes dynamic
multicast routing not work.  Related to this, when enabling IFF_PROMISC
in switch mode, all registered multicast addresses are flushed, resulting
in only broadcast and unicast traffic being received.

A new cpsw_ale_set_allmulti function now scans through the ALE entry
table and adds/removes the host port from the unregistered multicast
port mask of each vlan entry depending on the state of IFF_ALLMULTI.
In promiscious mode, cpsw_ale_set_allmulti is used to force reception
of all multicast traffic in addition to the unicast and broadcast traffic.

With this change dynamic multicast and promiscious mode both work in

If a driver supports reading EEPROM but no EEPROM is installed in the system,
the driver's get_eeprom_len function returns 0. ethtool will subsequently
try to read that zero-length EEPROM anyway. If the driver does not support
EEPROM access at all, this operation will return -EOPNOTSUPP. If the driver
does support EEPROM access but no EEPROM is installed, the operation will
return -EINVAL. Return -EOPNOTSUPP in both cases for consistency.

Because bonding stats are usually sum of slave stats, it was
not easy to account for tx drops at bonding layer.

We can use dev->tx_dropped for this, as this counter is later
added to the device stats (in dev_get_stats())

This extends the idea we had in commit ee637714 ("bonding: Simplify
the xmit function for modes that use xmit_hash") for bond_3ad_xor_xmit()

With legacy booting, the platform init code was taking care of
the configuring of GPIOs. With device tree based booting, things
may or may not work depending what bootloader has configured or
if the legacy platform code gets called.

Let's add support for the pwrdn and reset GPIOs to the smc91x
driver to fix the issues of smc91x not working properly when
booted in device tree mode.

And let's change n900 to use these settings as some versions
of the bootloader do not configure things properly causing

48 (ENOTSUP) if the disk has an EFI label. VTOC disk labels are already
handled by directly reading the disk in block/partitions/sun.c (enabled by
CONFIG_SUN_PARTITION which defaults to y on SPARC). Since port->label is

Pull tracing fix from Steven Rostedt:
 "ARM has system calls outside the NR_syscalls range, and the generic
  tracing system does not support that and without checks, it can cause
  an oops to be reported.

  Rabin Vincent added checks in the return code on syscall events to
  make sure that the system call number is within the range that tracing
  knows about, and if not, simply ignores the system call.

  The system call tracing infrastructure needs to be rewritten to handle
  these cases better, but for now, to keep from oopsing, this patch will
  do"

Pull documentation fixes from Jonathan Corbet:
 "So this is my first pull request since I rashly agreed to look after
  the documentation subtree.  It contains some typo fixes, a few minor
  documentation improvements, and, most importantly, fixes for a couple
  of build problems in various bits of sample code.

  I fully intend to start sending pull requests with signed tags.
  However, due to poor planning on my part and the general obnoxiousness
  of life, I'm 2000 miles away from my private key which is sitting on a
  powered-down machine.  This should be fixed before my next request.

  Meanwhile git.lwn.net is a machine under my control, the patches are
  all trivial, and all have done time in linux-next"

For Renesas USB 3.0 host controller, when unplugging the usb hub which
has the RTL8153 plugged, the driver would get -EPROTO for interrupt
transfer. There is high probability to get the information of "HC died;
cleaning up", if the driver continues to submit the interrupt transfer
before the disconnect() is called.

This reverts commit 68da1664.

It turns out that the assertion about scope of regressions due to
always keeping keyboard controller in legacy mode was proven wrong.
There are laptops, such as Clevo W650SH, that only have internal
touchpad (no external PS/2 ports), that require active multiplexing
mode to switch the touchpad (Elantech) into native mode instead of
basic PS/2 emulation.
