Replace dev_kfree_skb with dev_consume_skb_any in emacs_start_xmit
which can be called in hard irq and other contexts.
emac_start_xmit always transmits the packet making dev_consume_skb
the appropriate function to call.

The VXLAN neigh_reduce() code is completely non-functional since
check-in. Specific errors:
1) The original code drops all packets with a multicast destination address,
even though neighbor solicitations are sent to the solicited-node
address, a multicast address. The code after this check was never run.
2) The neighbor table lookup used the IPv6 header destination, which is the
solicited node address, rather than the target address from the
neighbor solicitation. So neighbor lookups would always fail if it
got this far. Also for L3MISSes.
3) The code calls ndisc_send_na(), which does a send on the tunnel device.
The context for neigh_reduce() is the transmit path, vxlan_xmit(),
where the host or a bridge-attached neighbor is trying to transmit
a neighbor solicitation. To respond to it, the tunnel endpoint needs
to do a *receive* of the appropriate neighbor advertisement. Doing a
send, would only try to send the advertisement, encapsulated, to the
remote destinations in the fdb -- hosts that definitely did not do the
corresponding solicitation.
4) The code uses the tunnel endpoint IPv6 forwarding flag to determine the
isrouter flag in the advertisement. This has nothing to do with whether
or not the target is a router, and generally won't be set since the
tunnel endpoint is bridging, not routing, traffic.
The patch below creates a proxy neighbor advertisement to respond to
neighbor solicitions as intended, providing proper IPv6 support for neighbor
reduction.

====================
net: davinci_emac: Fix interrupt requests and error handling
since commit 6892b41d9701283085b655c6086fb57a5d63fa47 (Linux 3.11) the
davinci_emac driver is broken. After doing ifconfig down, ifconfig up,
requesting the interrupts for the driver fails. The interface remains dead
until the board is rebooted.
The first patch in this patchset reverts commit
6892b41d9701283085b655c6086fb57a5d63fa47 partially and makes the driver
useable again.
During the work on the first patch, a number of bugs in the error handling
of the driver's ndo_open code were found. The second patch fixes these bugs.
I believe the first patch meets the rules for stable kernels, I therefore added
the stable tag to this patch. The second patch is just cleanup, the code
that is fixed by this patch is only executed in case of an error.

If an error occurs during the initialization in emac_dev_open() (the
driver's ndo_open function), interrupts, DMA descriptors etc. must be freed.
The current rollback code is buggy in several ways.
1) Freeing the interrupts. The current code will not free all interrupts
that were requested by the driver. Furthermore, the code tries to do a
platform_get_resource(priv->pdev, IORESOURCE_IRQ, -1) in its last
iteration.
This patch fixes these bugs.
2) Wrong order of err: and rollback: labels. If the setup of the PHY in
the code fails, the interrupts that have been requested before are
not freed:
request irq
if requesting irqs fails, goto rollback
setup phy
if phy setup fails, goto err
return 0
rollback:
free irqs
err:
This patch brings the code into the correct order.
3) The code calls napi_enable() and emac_int_enable(), but does not
undo both in case of an error.
This patch adds calls of emac_int_disable() and napi_disable() to the
rollback code.
4) RX DMA descriptors are not freed in case of an error: Right before
requesting the irqs, the function creates DMA descriptors for the
RX channel. These RX descriptors are never freed when we jump to either
rollback or err.
This patch adds code for freeing the DMA descriptors in the case of
an initialization error. This required a modification of
cpdma_ctrl_stop() in davinci_cpdma.c: We must be able to call this
function to free the DMA descriptors while the DMA channels are
in IDLE state (before cpdma_ctlr_start() was called).
Tested on a custom board with the Texas Instruments AM1808.

In commit 6892b41d9701283085b655c6086fb57a5d63fa47
Author: Lad, Prabhakar <prabhakar.csengg@gmail.com>
Date: Tue Jun 25 21:24:51 2013 +0530
net: davinci: emac: Convert to devm_* api
the call of request_irq is replaced by devm_request_irq and the call
of free_irq is removed. But since interrupts are requested in
emac_dev_open, doing ifconfig up/down on the board requests the
interrupts again each time, causing devm_request_irq to fail. The
interface is dead until the device is rebooted.
This patch reverts said commit partially: It changes the driver back
to use request_irq instead of devm_request_irq, puts free_irq back in
place, but keeps the remaining changes of the original patch.

In arch_cpu_idle() we must enable %pil based interrupts before
potentially invoking the hypervisor cpu yield call.
As per the Hypervisor API documentation for cpu_yield:
Interrupts which are blocked by some mechanism other that
pstate.ie (for example %pil) are not guaranteed to cause
a return from this service.
It seems that only first generation Niagara chips are hit by this
bug. My best guess is that later chips implement this in hardware
and wake up anyways from %pil events, whereas in first generation
chips the yield is implemented completely in hypervisor code and
requires %pil to be enabled in order to wake properly from this
call.

====================
Intel Wired LAN Driver Updates
This series contains updates to igb, ixgbe, ixgbevf, i40e and i40evf.
Anjali provides a i40e/i40evf patch to add Energy Efficient Ethernet
Low Power Idle stats and a fix for i40e to change the string
"Side Band" to "Sideband" for consistency.
Mitch provides 2 patches for i40evf to fix if the driver encounters
an error while communicating with the PF driver, do not shut down the
admin queue unconditionally. Add an error message when the admin
queue message never completes and fix formatting on another message
that was unnecessarily wrapped.
Mark provides a ixgbe patch and five ixgbevf patches. Fix a possible
infinite recursion when an adapter is removed and registers all read
as all one's in ixgbe_clear_vmdq_generic() and ixgbe_clear_rar_generic().
Converts macros to static inline functions to align kernel coding standard
and prepare for adding Live Error Recovery (LER) to ixgbevf. Change the
ethtool register test to use the normal register accessor functions and
eliminate macors used for calling register test functions to make error
exits more clear. Checks all register reads for adapter removal by checking
the status register after any register read that returns all F's since the
status register will never return 0xFFFFFFFF unless the adapter is removed.
Jacob implements SIOCGHWTSTAMP ioctl for igb which enables user processes
to read the current hardware stamp config settings non-destructively.
Todd adds the initial register read and write for surprise removal (LER)
for igb.
Christian Engelmayer fixes an igb memory leak in the igb_get_module_eeprom()
error handling path.
Ken Ichikawa provides a fix for igb, specifically for 82575 hardware to
specify -1 to the phc_index for ethtool's get_ts_info, otherwise a wrong
value will be set to the phc_index.
Christopher Paasch fixes a null pointer dereference in igb and makes sure
to unset the HAS_MSIX flag when the driver falls back to MSI only.

Fixes a build break due to the undeclared use of irq_of_parse_and_map()
and of_iomap(). This build break was apparently introduced while the
driver was unbuildable due to the bug fixed by
62c19c9d29e65086e5ae76df371ed2e6b23f00cd ("i2c: Remove usage of
orphaned symbol OF_I2C"). When 62c19c was added in v3.14-rc7,
the driver was enabled again, breaking the powerpc mpc85xx_defconfig
and mpc85xx_smp_defconfig.
62c19c is marked for stable, so this should go there as well.

ASoC: Updates for v3.15
This is mostly a few additional fixes from Lars-Peter, a new driver and
cleaning up a git failure with merging the Intel branch (combined with
an xargs failure to pay attention to error codes). The history lists a
bunch of additional commits for the branch but the content of those
commits is actually present already but not recorded in history due to
git failing. Unfortunately xargs is used in the merge script and it
doesn't do a good job of noticing errors from the commands it invokes.

ASoC: Updates for v3.15
Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:
- Lots of cleanups from Takashi for enumerations; the original API for
these was error prone so he's refactored lots of code to use more
modern APIs which avoid issues.
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle.
- Provide both manually and transparently locked DAPM APIs rather than
a mix of the two fixing some concurrency issues.
- Start converting CODEC drivers to use separate bus interface drivers
rather than having them all in one file helping avoid dependency
issues.
- DPCM support for Intel Haswell and Bay Trail platforms.
- Lots of work on improvements for simple-card, DaVinci and the Renesas
rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
CSR SiRF SoC.

Since this macro is identical to pgprot_writecombine() and is only used
in a single place, remove it completely to avoid confusion. On ARMv7+
processors, the coherent DMA mapping must be Normal NonCacheable (a.k.a.
writecombine) to avoid mismatched hardware attribute aliases (with the
kernel linear mapping as Normal Cacheable).

The current dma_ops do not specify an mmap function so maping
falls back to the default implementation. There are at least
two issues with using the default implementation:
1) The pgprot is always pgprot_noncached (strongly ordered)
memory even with coherent operations
2) dma_common_mmap calls virt_to_page on the remapped non-coherent
address which leads to invalid memory being mapped.
Fix both these issue by implementing a custom mmap function which
correctly accounts for remapped addresses and sets vm_pg_prot
appropriately.
