This is a resubmission.
Added kfree() in ax88179_get_eeprom to prevent memory leakage.
Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts.
Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)".
Fixed endianness issue on big endian systems and verified this driver on iBook G4.
Removed steps that change net->features in ax88179_set_features function.
Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array.
Fixed the issue that the default MTU is not 1500.
Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an
MTU higher than 1500.
Fixed indentation and empty line coding style errors.
The _nopm version usb functions were added to access register in suspend and resume functions.
Serveral variables allocted dynamically were removed and replaced by stack variables.
ax88179_get_eeprom were modified from asix_get_eeprom in asix_common.
This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0
to gigabit ethernet adapters. It's based on the AX88xxx driver but
the usb commands used to access registers for AX88179 are completely different.
This driver had been verified on x86 system with AX88179/AX88178A and
Sitcomm LN-032 USB dongles.

Fix memory leak in phy_device_free() for the case when phy_device*
returned by phy_device_create() is not registered in the system.
Bug description:
phy_device_create() sets name of kobject using dev_set_name(), which
allocates memory using kvasprintf(), but this memory isn't freed if
the underlying device isn't registered properly, because kobject_cleanup()
is not called in that case. This can happen (and actually is happening on
our machines) if phy_device_register(), called by mdiobus_scan(), fails.
Patch description:
Embedded struct device is initialized in phy_device_create() and it
counterpart phy_device_free() just drops one reference to the device,
which leads to proper deinitialization including releasing the kobject
name memory.

On many different chips, important aspects of the MAC state are not
fully cleared by a warm reset. This can show up as tx/rx hangs, those
annoying "DMA failed to stop in 10 ms..." messages or other quirks.
On AR933x, the chip can occasionally get stuck in a way that only a
driver unload/reload or a reboot would bring it back to life.
With this patch, a full reset is issued when bringing the chip out of
FULL-SLEEP state (after idle), or if either Rx or Tx was not shut down
properly. This makes the DMA related error messages disappear completely
in my tests on AR933x, and the chip does not get stuck anymore.

from the computer store adjacent to linux.conf.au 2013 in
Canberra (Australia). A web search shows other recent

emergent virus, our age of e-commerce and airmail allows
underdocumented hardware to spread around the world instantly

Paige Thompson, infected via eBay, discovered that the HG20F9

This patch uses her discovery to update the restructured Asix

Some fixes that should go into 3.9:
1. Fix packet corruption when using non-coherent RX DMA buffers.
2. Fix occasional watchdog misfiring when changing MTU or ring size.
These are longstanding bugs and should be fixed in stable as well, but
I'd like to review other recent fixes first and send a separate request
for stable inclusion.

When stations are removed while packets are in the queue,
we drain the queues first, and then remove the stations.
If this happens in AP mode while the interface is removed
the MAC context might be removed from the firmware before
we removed the station(s), resulting in a SYSASSERT 3421.
This is because we remove the MAC context from the FW in
stop_ap(), but only flush the station drain work later in
remove_interface().
Refactor the code a bit to have a common MAC context
removal preparation first to solve this.

The FH hardware will always write back to the scratch field
in commands, even host commands not just TX commands, which
can overwrite parts of the command. This is problematic if
the command is re-used (with IWL_HCMD_DFL_NOCOPY) and can
cause calibration issues.
Address this problem by always putting at least the first
16 bytes into the buffer we also use for the command header
and therefore make the DMA engine write back into this.
For commands that are smaller than 16 bytes also always map
enough memory for the DMA engine to write back to.

This branch contains the usual set of individual driver improvements and
bug fixes, as well as updates to the core code. The more notable changes
include:
- Internally add new API for referencing GPIOs by gpio_desc instead of
number. Eventually this will become a public API
- ACPI GPIO binding support

A new driver has been added to support the PWM mode of the timer counter
blocks found on Atmel AT91 SoCs. The VT8500 driver now supports changing
the PWM signal polarity and the TI drivers (EHRPWM and ECAP) gained
suspend and resume functionality.
User drivers can now query the core for whether access to a PWM device
will sleep (if the PWM chip is on a slow bus such as I2C or SPI).
The pwm-backlight driver now handles the backlight BL_CORE_FBBLANK state
in addition to the FB layer's blanking states.
To round things off, a few fixes and cleanups are also included.

We must only ever stop TX queues when they are full or the net device
is not 'ready' so far as the net core, and specifically the watchdog,
is concerned. Otherwise, the watchdog may fire *immediately* if no
packets have been added to the queue in the last 5 seconds.
The device is ready if all the following are true:
(a) It has a qdisc
(b) It is marked present
(c) It is running
(d) The link is reported up
(a) and (c) are normally true, and must not be changed by a driver.
(d) is under our control, but fake link changes may disturb userland.
This leaves (b). We already mark the device absent during reset
and self-test, but we need to do the same during MTU changes and ring
reallocation. We don't need to do this when the device is brought
down because then (c) is already false.

We assume that the mapping between DMA and virtual addresses is done
on whole pages, so we can find the page offset of an RX buffer using
the lower bits of the DMA address. However, swiotlb maps in units of
2K, breaking this assumption.
Add an explicit page_offset field to struct efx_rx_buffer.
Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
We may currently allocate two RX DMA buffers to a page, and only unmap
the page when the second is completed. We do not sync the first RX
buffer to be completed; this can result in packet loss or corruption
if the last RX buffer completed in a NAPI poll is the first in a page
and is not DMA-coherent. (In the middle of a NAPI poll, we will
handle the following RX completion and unmap the page *before* looking
at the content of the first buffer.)

Pull drm merge from Dave Airlie:
"Highlights:
- TI LCD controller KMS driver
- TI OMAP KMS driver merged from staging
- drop gma500 stub driver
- the fbcon locking fixes
- the vgacon dirty like zebra fix.
- open firmware videomode and hdmi common code helpers
- major locking rework for kms object handling - pageflip/cursor
won't block on polling anymore!
- fbcon helper and prime helper cleanups
- i915: all over the map, haswell power well enhancements, valleyview
macro horrors cleaned up, killing lots of legacy GTT code,
- radeon: CS ioctl unification, deprecated UMS support, gpu reset
rework, VM fixes
- nouveau: reworked thermal code, external dp/tmds encoder support
(anx9805), fences sleep instead of polling,
- exynos: all over the driver fixes."
Lovely conflict in radeon/evergreen_cs.c between commit de0babd60d
("drm/radeon: enforce use of radeon_get_ib_value when reading user cmd")
and the new changes that modified that evergreen_dma_cs_parse()
function.

Merge tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux
Pull module update from Rusty Russell:
"The sweeping change is to make add_taint() explicitly indicate whether
to disable lockdep, but it's a mechanical change."
* tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux:
MODSIGN: Add option to not sign modules during modules_install
MODSIGN: Add -s <signature> option to sign-file
MODSIGN: Specify the hash algorithm on sign-file command line
MODSIGN: Simplify Makefile with a Kconfig helper
module: clean up load_module a little more.
modpost: Ignore ARC specific non-alloc sections
module: constify within_module_*
taint: add explicit flag to show whether lock dep is still OK.
module: printk message when module signature fail taints kernel.
The name of FEATURE_AUTOSUSPEND is very misleading and the actual
meaning is remote wakeup, but a device incapable of remote wakeup
still can support USB autosuspend under some situations, so rename
it to avoid misunderstanding.
