This patch adds skb_remcsum_process and skb_gro_remcsum_process to
perform the appropriate adjustments to the skb when receiving
remote checksum offload.
Updated vxlan and gue to use these functions.
Tested: Ran TCP_RR and TCP_STREAM netperf for VXLAN and GUE, did
not see any change in performance.

The commone register macors (e.g. RSR) is too commont to drivers, it may

when 'external' entity notifies the aging
When 'learned_sync' flag is turned on, the offloaded switch
port syncs learned MAC addresses to bridge's FDB via switchdev notifier
(NETDEV_SWITCH_FDB_ADD). Currently, FDB entries learnt via this mechanism are
wrongly being deleted by bridge aging logic. This patch ensures that FDB
entries synced from offloaded switch ports are not deleted by bridging logic.
Such entries can only be deleted via switchdev notifier
(NETDEV_SWITCH_FDB_DEL).

Freescale ethernet controllers have the capability to re-assemble fragmented
data into a single ethernet frame. This patch uses this capability and
implements NETIP_F_SG feature into the fs_enet ethernet driver.

A typical qdisc setup is the following :
bond0 : bonding device, using HTB hierarchy
eth1/eth2 : slaves, multiqueue NIC, using MQ + FQ qdisc
XPS allows to spread packets on specific tx queues, based on the cpu
doing the send.
Problem is that dequeues from bond0 qdisc can happen on random cpus,
due to the fact that qdisc_run() can dequeue a batch of packets.
CPUA -> queue packet P1 on bond0 qdisc, P1->ooo_okay=1
CPUA -> queue packet P2 on bond0 qdisc, P2->ooo_okay=0
CPUB -> dequeue packet P1 from bond0
enqueue packet on eth1/eth2
CPUC -> dequeue packet P2 from bond0
enqueue packet on eth1/eth2 using sk cache (ooo_okay is 0)
get_xps_queue() then might select wrong queue for P1, since current cpu
might be different than CPUA.
P2 might be sent on the old queue (stored in sk->sk_tx_queue_mapping),
if CPUC runs a bit faster (or CPUB spins a bit on qdisc lock)
Effect of this bug is TCP reorders, and more generally not optimal
TX queue placement. (A victim bulk flow can be migrated to the wrong TX
queue for a while)
To fix this, we have to record sender cpu number the first time
dev_queue_xmit() is called for one tx skb.
We can union napi_id (used on receive path) and sender_cpu,
granted we clear sender_cpu in skb_scrub_packet() (credit to Willem for
this union idea)

SMBus access functions assume that 16-bit values are formatted as
little endian numbers. The direct i2c access functions in regmap,
however, assume that 16-bit values are formatted as big endian numbers.
As a result, the current code returns different values if an i2c chip's
16-bit registers are accessed through i2c access functions vs. SMBus
access functions.
Use regmap_smbus_read_word_swapped and regmap_smbus_write_word_swapped
for 16-bit SMBus accesses if a chip is configured as REGMAP_ENDIAN_BIG.
If the chip is configured as REGMAP_ENDIAN_LITTLE, keep using
regmap_smbus_write_word_data and regmap_smbus_read_word_data. Otherwise
reject registration if the controller does not support direct i2c accesses.

Pull ARM fixes from Russell King:
"A number of ARM fixes, the biggest is fixing a regression caused by
appended DT blobs exceeding 64K, causing the decompressor fixup code
to fail to patch the DT blob. Another important fix is for the ASID
allocator from Will Deacon which prevents some rare crashes seen on
some systems. Lastly, there's a build fix for v7M systems when printk
support is disabled.
The last two remaining fixes are more cosmetic - the IOMMU one
prevents an annoying harmless warning message, and we disable the
kernel strict memory permissions on non-MMU which can't support it
anyway"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8299/1: mm: ensure local active ASID is marked as allocated on rollover
ARM: 8298/1: ARM_KERNMEM_PERMS only works with MMU enabled

Sending data in high speed then introducing a busoff results
in spurious BUS_ERROR events from the USBCan-II firmware directly
_after_ the triggered BUS_OFF event.
In the current CAN state handling code, this will lead to an
invalid can state of ACTIVE, ERROR, or PASSIVE even though the
CAN controller has been already shut down due to the busoff.
Guard the state handling code from such invalid events.

clk_set_rate() tries to take clk's prepare_lock mutex while being in atomic
context entered in sdhci_do_set_ios().
The solution is inspired by similar situation in sdhci_set_power() also called
from sdhci_do_set_ios():
spin_unlock_irq(&host->lock);
mmc_regulator_set_ocr(mmc, mmc->supply.vmmc, vdd);
spin_lock_irq(&host->lock);
Note that since sdhci_s3c_set_clock() sets SDHCI_CLOCK_CARD_EN, proposed change
first resets this bit. It is reset anyway (by setting SDHCI_CLOCK_INT_EN bit
only) after call to clk_set_rate() in order to wait for the clock to stabilize
and is set again as soon as the clock becomes stable.
