41bb73eeac mac80211: remove SSID driver code
Remove the SSID from the driver API since now there is no
driver that requires knowing the SSID and I think it's
unlikely that any hardware design that does require the
SSID will play well with mac80211.

This also removes support for setting the SSID in master
mode which will require a patch to hostapd to not try.

b23f99bcfa adm8211: remove SSID code
Since adm8211 currently doesn't implement IBSS mode anyway,
it can't be using the SSID. And if/when it does implement
IBSS mode, we'll have to see how to make it beacon anyway.

71c11fb57b b43/legacy: remove SSID code
The SSID programmed into the device is used by the ucode only
to reply to probe requests, a functionality we disable anyway
because it doesn't fit with the mac80211/hostapd programming
model. Therefore, it isn't useful to program the SSID into
device.

a57a59f247 iwlwifi: remove implicit direct scan
When an undirected scan is requested and iwlwifi is not associated but
the user has set an SSID (and maybe was associated with that network at
some point) then iwlwifi will assume the user wanted to scan for this
SSID which seems wrong. Remove this code.

4ceb7b6ae2 netdevice libertas: Fix directly reference of netdev->priv
We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.

Different to readonly reference of netdev->priv, in this driver, netdev->priv
was changed. I use netdev->ml_priv to replace netdev->priv.

505d4f73dd net: Guaranetee the proper ordering of the loopback device. v2
I was recently hunting a bug that occurred in network namespace
cleanup.  In looking at the code it became apparrent that we have
and will continue to have cases where if we have anything going
on in a network namespace there will be assumptions that the
loopback device is present.   Things like sending igmp unsubscribe
messages when we bring down network devices invokes the routing
code which assumes that at least the loopback driver is present.

Therefore to avoid magic initcall ordering hackery that is hard
to follow and hard to get right insert a call to register the
loopback device directly from net_dev_init().    This guarantes
that the loopback device is the first device registered and
the last network device to go away.

But do it carefully so we register the loopback device after
we clear dev_boot_phase.

06a7f05876 atmel_serial: keep clock off when it's not needed
The atmel_serial driver is mismanaging its clock by leaving it on at all
times ...  the whole point of clock management is to leave it off unless
it's actively needed, which conserves power!!

Although the kernel doesn't actually hang without my fix, it does
discard quite a lot of early console output.

The result still looks correct:

          usart        users= 1 on   35000000 Hz, for atmel_usart.0
          usart        users= 0 off  35000000 Hz, for atmel_usart.2

when using ttyS0 as serial console.

a684e7d330 fbdev: fix fb_compat_ioctl() deadlocks
commit 3e680aae4e ("fb: convert
lock/unlock_kernel() into local fb mutex") introduced several deadlocks
in the fb_compat_ioctl() path, as mutex_lock() doesn't allow recursion,
unlike lock_kernel().  This broke frame buffer applications on 64-bit
systems with a 32-bit userland.

commit 120a37470c ("framebuffer compat_ioctl
deadlock") fixed one of the deadlocks.

This patch fixes the remaining deadlocks:
  - Revert commit 120a37470c,
  - Extract the core logic of fb_ioctl() into a new function do_fb_ioctl(),
  - Change all callsites of fb_ioctl() where info->lock is already held to
    call do_fb_ioctl() instead,
  - Add sparse annotations to all routines that take info->lock.

c793033945 ath5k: correct handling of rx status fields
ath5k_rx_status fields rs_antenna and rs_more are u8s, but we
were setting them with bitwise ANDs of 32-bit values.

As a consequence, jumbo frames would not be discarded as intended.
Then, because the hw rate value of such frames is zero, and, since
"ath5k: rates cleanup", we do not fall back to the basic rate, such
packets would trigger the following WARN_ON:

Avoid the sleep by changing iwl_scan_cancel_timeout with

f1cd14ae52 md: linear: Fix a division by zero bug for very small arrays.
We currently oops with a divide error on starting a linear software
raid array consisting of at least two very small (< 500K) devices.

The bug is caused by the calculation of the hash table size which
tries to compute sector_div(sz, base) with "base" being zero due to
the small size of the component devices of the array.

Fix this by requiring the hash spacing to be at least one which
implies that also "base" is non-zero.

This bug has existed since about 2.6.14.

fd989c8332 bonding: alternate agg selection policies for 802.3ad
This patch implements alternative aggregator selection policies
for 802.3ad.  The existing policy, now termed "stable," selects the active
aggregator by greatest bandwidth, and only reselects a new aggregator
if the active aggregator is entirely disabled (no more ports or all ports
down).

	This patch adds two new policies: bandwidth and count, selecting
the active aggregator by total bandwidth (like the stable policy) or by
the number of ports in the aggregator, respectively.  These two policies
also differ from the stable policy in that they will reselect the active
aggregator when availability-related changes occur in the bond (e.g.,
link state change).

	This permits "gang failover" within 802.3ad, allowing redundant
aggregators along parallel paths to always maintain the "best" aggregator
as the active aggregator (rather than having to wait for the active to
entirely fail).

	This patch also updates the driver version to 3.5.0.

305d552acc bonding: send IPv6 neighbor advertisement on failover
This patch adds better IPv6 failover support for bonding devices,
especially when in active-backup mode and there are only IPv6 addresses
configured, as reported by Alex Sidorenko.

- Creates a new file, net/drivers/bonding/bond_ipv6.c, for the
   IPv6-specific routines.  Both regular bonds and VLANs over bonds
   are supported.

- Adds a new tunable, num_unsol_na, to limit the number of unsolicited
   IPv6 Neighbor Advertisements that are sent on a failover event.
   Default is 1.

- Creates two new IPv6 neighbor discovery functions:

   ndisc_build_skb()
   ndisc_send_skb()

   These were required to support VLANs since we have to be able to
   add the VLAN id to the skb since ndisc_send_na() and friends
   shouldn't be asked to do this.  These two routines are basically
   __ndisc_send() split into two pieces, in a slightly different order.

- Updates Documentation/networking/bonding.txt and bumps the rev of bond
   support to 3.4.0.

On failover, this new code will generate one packet:

- An unsolicited IPv6 Neighbor Advertisement, which helps the switch
   learn that the address has moved to the new slave.

Testing has shown that sending just the NA results in pretty good
behavior when in active-back mode, I saw no lost ping packets for example.

ae33bc40c0 net: Guaranetee the proper ordering of the loopback device.
I was recently hunting a bug that occurred in network namespace
cleanup.  In looking at the code it became apparrent that we have
and will continue to have cases where if we have anything going
on in a network namespace there will be assumptions that the
loopback device is present.   Things like sending igmp unsubscribe
messages when we bring down network devices invokes the routing
code which assumes that at least the loopback driver is present.

Therefore to avoid magic initcall ordering hackery that is hard
to follow and hard to get right insert a call to register the
loopback device directly from net_dev_init().    This guarantes
that the loopback device is the first device registered and
the last network device to go away.

467622ef2a [MTD] [NOR] Fix cfi_send_gen_cmd handling of x16 devices in x8 mode (v4)
For "unlock" cycles to 16bit devices in 8bit compatibility mode we need
to use the byte addresses 0xaaa and 0x555. These effectively match
the word address 0x555 and 0x2aa, except the latter has its low bit set.

Most chips don't care about the value of the 'A-1' pin in x8 mode,
but some -- like the ST M29W320D -- do. So we need to be careful to
set it where appropriate.

cfi_send_gen_cmd is only ever passed addresses where the low byte
is 0x00, 0x55 or 0xaa. Of those, only addresses ending 0xaa are
affected by this patch, by masking in the extra low bit when the device
is known to be in compatibility mode.

[dwmw2: Do it only when (cmd_ofs & 0xff) == 0xaa]
v4: Fix  stupid typo in cfi_build_cmd_addr that failed to compile
    I'm writing this patch way to late at night.
v3: Bring all of the work back into cfi_build_cmd_addr
    including calling of map_bankwidth(map) and cfi_interleave(cfi)
    So every caller doesn't need to.
v2: Only modified the address if we our device_type is larger than our
    bus width.

3c324283e6 sata_nv: fix generic, nf2/3 detection regression
All three flavors of sata_nv's are different in how their hardreset
behaves.

* generic: Hardreset is not reliable.  Link often doesn't come online
  after hardreset.

* nf2/3: A little bit better - link comes online with longer debounce
  timing.  However, nf2/3 can't reliable wait for the first D2H
  Register FIS, so it can't wait for device readiness or classify the
  device after hardreset.  Follow-up SRST required.

* ck804: Hardreset finally works.

The core layer change to prefer hardreset and follow up changes
exposed the above issues and caused various detection regressions for
all three flavors.  This patch, hopefully, fixes all the known issues
and should make sata_nv error handling more reliable.

cadef677e4 sata_promise: add ATA engine reset to reset ops
Promise ATA engines need to be reset when errors occur.
That's currently done for errors detected by sata_promise itself,
but it's not done for errors like timeouts detected outside of
the low-level driver.

The effect of this omission is that a timeout tends to result
in a sequence of failed COMRESETs after which libata EH gives
up and disables the port. At that point the port's ATA engine
hangs and even reloading the driver will not resume it.

To fix this, make sata_promise override ->hardreset on SATA
ports with code which calls pdc_reset_port() on the port in
question before calling libata's hardreset. PATA ports don't
use ->hardreset, so for those we override ->softreset instead.

babcda74e9 drivers/net: Kill now superfluous ->last_rx stores.
The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the
bonding ARP monitor.

Drivers need not do it any more.

Some cases had to be skipped over because the drivers
were making use of the ->last_rx value themselves.

6cf3f41e6c bonding, net: Move last_rx update into bonding recv logic
The only user of the net_device->last_rx field is bonding.
This patch adds a conditional update of last_rx to the bonding special
logic in skb_bond_should_drop, causing last_rx to only be updated when
the ARP monitor is running.

	This frees network device drivers from the necessity of
updating last_rx, which can have cache line thrash issues.

This patch refines the phylib support in the tg3 driver.  The patch does
the following things :

* Rename tg3_mdio_config() to tg3_mdio_config_5785().  The 5785 will be
  the only device that will use it so the name might as well reflect
  that.
* Fix a memory leak if mdiobus_register() fails.
* Add code to deal with phy device detection failures.
* Add code to correct the supported list of phy features based on the
  MAC <=> PHY interface.

05ac4cb7df tg3: Refine power management and WOL code
Commit 12dac0756d ("tg3: adapt tg3 to
use reworked PCI PM code") introduced the new PCI PM API to the tg3
driver.  The patch was understandably conservative, so this patch
elaborates on that work.

The patch starts by creating a single point in tg3_set_power_state()
to decide whether or not to enable WOL.  The rest of the code in
tg3_set_power_state() was then pivoted to use the result of this
decision.

The patch then makes sure the device is allowed to wakeup before
reporting whether or not WOL is currently enabled.  The final hunks of
the patch consolidate where the WOL capability and WOL enabled flags
are set to a single location.

b2aee1545d tg3: Preserve DASH connectivity when WOL enabled
DASH firmware runs on the APE side of the chip, but it requires a few MAC
to be programmed correctly.

When WOL is enabled and management firmware is disabled, incoming
packets are evaluated and discarded at the chip's rule processor.
When management firmware is enabled, the hardware must be informed that
there are agents further up the stack that still use the incoming
frames.  Normally management firmware will configure the MAC correctly
on its own, but there can be cases where the setting could get clobbered
by the driver.  The first hunk of this patch preserves this setting.

The second hunk of this patch wipes out the driver present signature of
the APE memory space.  By doing so, the DASH firmware can assume
driver absent behavior.

ee04448d88 mv643xx_eth: fix SMI bus access timeouts
The mv643xx_eth mii bus implementation uses wait_event_timeout() to
wait for SMI completion interrupts.

If wait_event_timeout() would return zero, mv643xx_eth would conclude
that the SMI access timed out, but this is not necessarily true --
wait_event_timeout() can also return zero in the case where the SMI
completion interrupt did happen in time but where it took longer than
the requested timeout for the process performing the SMI access to be
scheduled again.  This would lead to occasional SMI access timeouts
when the system would be under heavy load.

The fix is to ignore the return value of wait_event_timeout(), and
to re-check the SMI done bit after wait_event_timeout() returns to
determine whether or not the SMI access timed out.
