The core implementation of cs_change didn't follow the documentation
which says that cs_change in the middle of the transfer means to briefly
deassert chip select, instead it followed buggy drivers which change the
polarity of chip select. Use a delay of 10us between deassert and
reassert simply from pulling numbers out of a hat.

There is no real reason why we require transfers to have a completion and
the only user of the completion now checks to see if one has been provided
before using it so stop enforcing this. This makes it more convenient for
drivers to chain multiple asynchronous transfers together.

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.

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.

upper limit on the page size as some the page size settings are 16-bit
in the hardware/firmware interface. In the current code, some parts
use BNX2_PAGE_SIZE which has a 16K upper limit and some parts use
PAGE_SIZE. On archs with >= 64K PAGE_SIZE, it generates some compile
warnings. Define a new CNIC_PAGE_SZIE which has an upper limit of

cnic_send_nlmsg() and cnic_copy_ulp_stats(), it was referencing the

This is a context modified revert of commit 6a9612e2cb22
("net: cdc_ncm: remove ncm_parm field") which introduced
a NCM specification violation, causing setup errors for
some devices. These errors resulted in the device and
host disagreeing about shared settings, with complete
failure to communicate as the end result.
The NCM specification require that many of the NCM specific
control reuests are sent only while the NCM Data Interface
is in alternate setting 0. Reverting the commit ensures that
we follow this requirement.

Fix from Zhang Rui.
- Moving the early ACPI initialization before timekeeping_init()
earlier in this cycle broke fast TSC calibration on at least one
system, so it needs to be done later, but still before
efi_enter_virtual_mode() to allow the EFI initialization to refer
to ACPI.
- A change related to code duplication reduction in the cpufreq core
inadvertently caused cpufreq intialization to fail for some CPUs
handled by intel_pstate by adding checks that may fail for that
driver, but aren't even necessary when it is used. The issue is
addressed by preventing those checks from run in the configurations
in which they aren't needed.
- If the Hardware Reduced ACPI flag is set in the ACPI tables, system
suspend, hibernation and ACPI power off will only work when special
sleep control and sleep status registeres are provided (their
addresses in the ACPI tables are not zero). If those registers are
not available, the features in question have no chances to work, so
they shouldn't even be regarded as supported. That helps with
power off in particular, because alternative power off methods may
be used then and they may actually work"

It has been reported that there is a new hardware version of the G27
in the 'wild'. This patch add's this new revision so that it can be
sent the command to switch to native mode.
