The SIT driver conflict consists of a bug fix being done by hand

The driver currently maps a page for DMA, divides the page into multiple
frags and posts them to the HW. It un-maps the page after data is received
on all the frags of the page. This scheme doesn't work when bounce buffers
are used for DMA (swiotlb=force kernel param).
This patch fixes this problem by calling dma_sync_single_for_cpu() for each
frag (excepting the last one) so that the data is copied from the bounce
buffers. The page is un-mapped only when DMA finishes on the last frag of
the page.
(Thanks Ben H. for suggesting the dma_sync API!)
This patch also renames the "last_page_user" field of be_rx_page_info{}
struct to "last_frag" to improve readability of the fixed code.

This patch is a modification of the patch originally proposed by
Xiaotian Feng <xtfeng@gmail.com>: https://lkml.org/lkml/2012/11/5/413
This new version disables DMA channel interrupts and ensures that the
tasklet wil not be scheduled again before calling tasklet_kill().
Unfortunately the updated patch was not released at that time due to
planned rework of Tsi721 mport driver to use threaded interrupts (which
has yet to happen). Recently the issue was reported again:
https://lkml.org/lkml/2014/2/19/762.
Description from the original Xiaotian's patch:
"Some drivers use tasklet_disable in device remove/release process,
tasklet_disable will inc tasklet->count and return. If the tasklet is
not handled yet under some softirq pressure, the tasklet will be
placed on the tasklet_vec, never have a chance to be excuted. This
might lead to a heavy loaded ksoftirqd, wakeup with pending_softirq,
but tasklet is disabled. tasklet_kill should be used in this case."
This patch is applicable to kernel versions starting from v3.5.

Commit bf6bddf1924e ("mm: introduce compaction and migration for
ballooned pages") introduces page_count(page) into memory compaction
which dereferences page->first_page if PageTail(page).
This results in a very rare NULL pointer dereference on the
aforementioned page_count(page). Indeed, anything that does
compound_head(), including page_count() is susceptible to racing with
prep_compound_page() and seeing a NULL or dangling page->first_page
pointer.
This patch uses Andrea's implementation of compound_trans_head() that
deals with such a race and makes it the default compound_head()
implementation. This includes a read memory barrier that ensures that
if PageTail(head) is true that we return a head page that is neither
NULL nor dangling. The patch then adds a store memory barrier to
prep_compound_page() to ensure page->first_page is set.
This is the safest way to ensure we see the head page that we are
expecting, PageTail(page) is already in the unlikely() path and the
memory barriers are unfortunately required.
Hugetlbfs is the exception, we don't enforce a store memory barrier
during init since no race is possible.

Macvlan currently inherits all of its features from the lower
device. When lower device disables offload support, this causes
macvlan to disable offload support as well. This causes
performance regression when using macvlan/macvtap in bridge
mode.
It can be easily demonstrated by creating 2 namespaces using
macvlan in bridge mode and running netperf between them:
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 10.0.0.1 () port 0 AF_INET
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
87380 16384 16384 20.00 1204.61
To restore the performance, we add software offload features
to the list of "always_on" features for macvlan. This way
when a namespace or a guest using macvtap initially sends a
packet, this packet will not be segmented at macvlan level.
It will only be segmented when macvlan sends the packet
to the lower device.

====================
Please pull this batch of fixes intended for the 3.14 stream...
For the mac80211 bits, Johannes says:
"This time I have a fix to get out of an 'infinite error state' in case
regulatory domain updates failed and two fixes for VHT associations: one
to not disconnect immediately when the AP uses more bandwidth than the
new regdomain would allow after a change due to association country
information getting used, and one for an issue in the code where
mac80211 doesn't correctly ignore a reserved field and then uses an HT
instead of VHT association."
For the iwlwifi bits, Emmanuel says:
"Johannes fixes a long standing bug in the AMPDU status reporting.
Max fixes the listen time which was way too long and causes trouble
to several APs."
Along with those, Bing Zhao marks the mwifiex_usb driver as _not_
supporting USB autosuspend after a number of problems with that have
been reported.

this is a pull request of 8 patches. Oliver Hartkopp contributes a patch which
removes the CAN FD compatibility for CAN 2.0 sockets, as it turns out that this
compatibility has some conceptual cornercases. The remaining 7 patches are by
me, they address a problem in the flexcan driver. When shutting down the
interface ("ifconfig can0 down") under heavy network load the whole system will
hang. This series reworks the actual sequence in close() and the transition
from and to the low power modes of the CAN controller.

This patch fixes a CPDMA RX Descriptor leak that occurs after taking
the interface down when the CPSW is in Dual MAC mode. Previously
the CPSW_ALE port was left open up which causes packets to be received
and processed by the RX interrupt handler and were passed to the
non active network interface where they were ignored.
The fix is for the slave_stop function of the selected interface
to disable the respective CPSW_ALE Port from forwarding packets. This
blocks traffic from being received on the inactive interface.

The commit 9b2777d6089bc ("ieee802154: add TX power control to

the questionable check of the return of __at86rf230_write() in the
exit path:
1) Both at86rf212_set_txpower() and __at86rf230_write() have the
same return type.
2) Whatever __at86rf230_write() returns becomes the return value of
at86rf212_set_txpower().
Thus, fix the exit path by getting rid of that check entirely.

In flexcan_chip_enable() and flexcan_chip_disable() fixed delays are used.
Experiments have shown that the transition from and to low power mode may take
several microseconds.
This patch adds a while loop which polls the Low Power Mode ACK bit (LPM_ACK)
that indicates a successfull mode change. If the function runs into a timeout a
error value is returned.

If flexcan_chip_start() in flexcan_open() fails, the interrupt is not freed,
this patch adds the missing cleanup.

When shutting down the CAN interface (ifconfig canX down) during high CAN bus
loads, the CAN core might hang and freeze the whole CPU.
This patch fixes the shutdown sequence by first disabling the CAN core then
disabling all interrupts.

When BlueFlame is turned on, control segment of the TX WQE is changed,
and the second line of it is used for QPN.
Changed code to use a union in the mlx4_wqe_ctrl_seg instead of casting.
This makes the code clearer and solves the static checker warning:
drivers/net/ethernet/mellanox/mlx4/en_tx.c:839 mlx4_en_xmit()
warn: potential memory corrupting cast 4 vs 2 bytes

This patch force conversion to u32 to fix the following sparse warning:
drivers/net/ethernet/mellanox/mlx4/fw.c:1822:53: warning: restricted __be32
degrades to integer
Casting to u32 is safe here, because token will be returned as is
from the hardware without any modification.

Currently, the EN driver uses a private static function
mlx4_en_mac_to_u64(). Move it to a common include file (driver.h)
for mlx4_en and mlx4_ib for further use.
