To prevent a race between the TX DMA engine and the CPU the writing of the
first transmit descriptor must be deferred until all following descriptors
have been updated. The network card may otherwise start transmitting before
all packet descriptors are set up correctly, which leads to data corruption
or an aborted transmit operation.
This deferral is already done in the non-TSO TX path, implement it also in
the TSO TX path.

The TX DMA engine requires that buffers with a size of 8 bytes or smaller
must be 64 bit aligned. This requirement may be violated when doing TSO,
as in this case larger skb frags can be broken up and transmitted in small
parts with then inappropriate alignment.
Fix this by checking for proper alignment before handing a buffer to the
DMA engine. If the data is misaligned realign it by copying it into the
TSO header data area.

====================
Intel Wired LAN Driver Updates 2015-10-19
This series contains updates to i40e and i40evf only.
Kiran adds a spinlock around code accessing VSI MAC filter list to
ensure that we are synchronizing access to the filter list, otherwise
we can end up with multiple accesses at the same time which can cause
the VSI MAC filter list to get in an unstable or corrupted state.
Jesse fixes overlong BIT defines, where the RSS enabling call were
mistakenly missed. Also fixes a bug where the enable function was
enabling the interrupt twice while trying to update the two interrupt
throttle rate thresholds for Rx and Tx, while refactoring the IRQ
enable function to simplify reading the flow. Addressed the high
CPU utilization of some small streaming workloads that the driver should
reduce CPU in.
Anjali fixes two X722 issues with respect to EEPROM checksum verify and
reading NVM version info. Fixed where a mask value was accidentally
replaced with a bit mask causing Flow Director sideband to be broken.
Alex Duyck fixes areas of the drivers which run from hard interrupt
context or with interrupts already disabled in netpoll, so use
napi_schedule_irqoff() instead of napi_schedule().
Mitch fixes the VF drivers to not easily give up when it is not able
to communicate with the PF driver.
Carolyn fixes a problem where our tools MAC loopback test, after driver
unbind would fail because the hardware was configured for multiqueue and
unbind operation did not clear this configuration. Also fixed a issue
where the NVMUpdate tool gets bad data from the PHY when using the PHY
NVM feature because of contention on the MDIO interface from getting
PHY capability calls from the driver during regular operations.
Catherine fixed an issue where we were checking if autoneg was allowed
to change before checking if autoneg was changing, these checks need to
be in the reverse order.
Jean Sacren fixes up an function header comment to align the kernel-docs
with the actual code.
v2: Cleaned up the use of spin_is_locked() in patch 1 based on feedback
from David Miller, since it always evaluates to zero on uni-processor
builds

When introduced in commit 1b5d514, the check 'if (hid_data->cc_index >= 0)'
in 'wacom_wac_finger_pre_report' was intended to switch where the driver
got the expected number of contacts from: HID_DG_CONTACTCOUNT if the usage
was present, or 'touch_max' otherwise. Unfortunately, an oversight worthy
of a brown paper bag (specifically, that 'cc_index' could never be negative)
meant that the latter 'else' clause would never be entered.
The patch prior to this one introduced a way for 'cc_index' to be negative,
but only if HID_DG_CONTACTCOUNT is present in some report _other_ than the
one being processed. To ensure the 'else' clause is also entered for devices
which don't have HID_DG_CONTACTCOUNT on _any_ report, we add the additional
constraint that 'cc_report' be non-zero (which is true only if the usage is
present in some report).

The cached indicies 'cc_index' and 'cc_value_index' introduced in 1b5d514
are only valid for a single report ID. If a touchscreen has multiple
reports with a HID_DG_CONTACTCOUNT usage, its possible that the values
will not be correct for the report we're handling, resulting in an
incorrect value for 'num_expected'. This has been observed with the Cintiq
Companion 2.
To address this, we store the ID of the report those indicies are valid
for in a new 'cc_report' variable. Before using them to get the expected
contact count, we first check if the ID of the report we're processing
matches 'cc_report'. If it doesn't, we update the indicies to point to
the HID_DG_CONTACTCOUNT usage of the current report (if it has one).

The new Intuos tablets added in eda01da and the Cintiq 13HD Touch added
in b4bf212 are capable of reporting 2048 levels of pressure. Although the
kernel reports the correct range to userspace, an oversight has resulted
in the driver ingoring the 11th pressure bit and only sending pressures
of 0 through 1023.
We could fix this issue by expanding the type check to include these
devices, but it makes much more sense to just have the driver look at
the device's maximum pressure when determining if it should read the
11th bit.

Suppose that we got a data crc error, and it triggers the mmc_reset.
mmc_reset will call mmc_send_status to see if HW reset was supported.
before issue CMD13, it will do retune, and if EMMC was in HS400 mode,
it will reduce frequency to 52Mhz firstly, then results in card init

The mmc_send_status was originally only done for mmc_test, should drop
