Some busy bits are available in the global register 1, such as the ATU
Busy bit. We may want to use this function to wait for them to change,
so add a new parameter to mv88e6352_wait() instead of hard-coding
REG_GLOBAL2.
In the meantime, since the REG_READ() macro already checks for error,
remove the redundant check for ret < 0.

This commit adds debug messages for the generic mv88e6xxx read and write
routines. The output is similar to this:
mdio-gpio mdio-gpio.0: <- addr: 0x1b reg: 0x05 val: 0x4000
mdio-gpio mdio-gpio.0: -> addr: 0x1b reg: 0x07 val: 0x3113
mdio-gpio mdio-gpio.0: -> addr: 0x1b reg: 0x08 val: 0x0330
mdio-gpio mdio-gpio.0: -> addr: 0x1b reg: 0x09 val: 0x0000
This is convenient to dynamically debug operations through debugfs with:
echo file mv88e6xxx.c +p > <debugfs>/dynamic_debug/control

While being in an ERROR_WARNING state, and receiving further
bus error events with error counters still in the ERROR_WARNING
range of 97-127 inclusive, the state handling code erroneously
reverts back to ERROR_ACTIVE.
Per the CAN standard, only revert to ERROR_ACTIVE when the
error counters are less than 96.
Moreover, in certain Kvaser models, the BUS_ERROR flag is
always set along with undefined bits in the M16C status
register. Thus use bitwise operators instead of full equality
for checking that register against bus errors.

On some x86 laptops, plugging a Kvaser device again after an
unplug makes the firmware always ignore the very first command.
For such a case, provide some room for retries instead of
completely exiting the driver init code.

Send expected argument to the URB completion hander: a CAN
netdevice instead of the network interface private context
`kvaser_usb_net_priv'.
This was discovered by having some garbage in the kernel
log in place of the netdevice names: can0 and can1.

Upon receiving a hardware event with the BUS_RESET flag set,
the driver kills all of its anchored URBs and resets all of
its transmit URB contexts.
Unfortunately it does so under the context of URB completion
handler `kvaser_usb_read_bulk_callback()', which is often
called in an atomic context.
While the device is flooded with many received error packets,
usb_kill_urb() typically sleeps/reschedules till the transfer
request of each killed URB in question completes, leading to
the sleep in atomic bug. [3]
In v2 submission of the original driver patch [1], it was
stated that the URBs kill and tx contexts reset was needed
since we don't receive any tx acknowledgments later and thus
such resources will be locked down forever. Fortunately this
is no longer needed since an earlier bugfix in this patch
series is now applied: all tx URB contexts are reset upon CAN
channel close. [2]
Moreover, a BUS_RESET is now treated _exactly_ like a BUS_OFF
event, which is the recommended handling method advised by
the device manufacturer.

Commit 69ad0dd7af22b61d9e0e68e56b6290121618b0fb
Author: Ezequiel Garcia <ezequiel.garcia@free-electrons.com>
Date: Mon May 19 13:59:59 2014 -0300
net: mv643xx_eth: Use dma_map_single() to map the skb fragments
caused a nasty regression by removing the support for highmem skb
fragments. By using page_address() to get the address of a fragment's
page, we are assuming a lowmem page. However, such assumption is incorrect,
as fragments can be in highmem pages, resulting in very nasty issues.
This commit fixes this by using the skb_frag_dma_map() helper,
which takes care of mapping the skb fragment properly. Additionally,
the type of mapping is now tracked, so it can be unmapped using
dma_unmap_page or dma_unmap_single when appropriate.
This commit also fixes the error path in txq_init() to release the
resources properly.

In order to stop the RX path accessing the RX ring while it's being
stopped or resized, we clear the interrupt mask (EESIPR) and then call
free_irq() or synchronise_irq(). This is insufficient because the
interrupt handler or NAPI poller may set EESIPR again after we clear
it. Also, in sh_eth_set_ringparam() we currently don't disable NAPI
polling at all.
I could easily trigger a crash by running the loop:
while ethtool -G eth0 rx 128 && ethtool -G eth0 rx 64; do echo -n .; done
and 'ping -f' toward the sh_eth port from another machine.
To fix this:
- Add a software flag (irq_enabled) to signal whether interrupts
should be enabled
- In the interrupt handler, if the flag is clear then clear EESIPR
and return
- In the NAPI poller, if the flag is clear then don't set EESIPR
- Set the flag before enabling interrupts in sh_eth_dev_init() and
sh_eth_set_ringparam()
- Clear the flag and serialise with the interrupt and NAPI
handlers before clearing EESIPR in sh_eth_close() and
sh_eth_set_ringparam()
After this, I could run the loop for 100,000 iterations successfully.

We must only ever stop TX queues when they are full or the net device
is not 'ready' so far as the net core, and specifically the watchdog,
is concerned. Otherwise, the watchdog may fire *immediately* if no
packets have been added to the queue in the last 5 seconds.
What's more, sh_eth_tx_timeout() will likely crash if called while
we're resizing the TX ring.
I could easily trigger this by running the loop:
while ethtool -G eth0 rx 128 && ethtool -G eth0 rx 64; do echo -n .; done

If an skb to be transmitted is shorter than the minimum Ethernet frame
length, we currently set the DMA descriptor length to the minimum but
do not add zero-padding. This could result in leaking sensitive
data. We also pass different lengths to dma_map_single() and
dma_unmap_single().
Use skb_padto() to pad properly, before calling dma_map_single().

In Dual EMAC, the default VLANs are used to segregate Rx packets between
the ports, so adding the same default VLAN to the switch will affect the
normal packet transfers. So returning error on addition of dual EMAC
default VLANs.
Even if EMAC 0 default port VLAN is added to EMAC 1, it will lead to
break dual EMAC port separations.

The device driver has plenty of command buffers available
per channel for channel command communication.
In the extremely rare case when there is no command buffer
available, return a NULL pointer and issue a warning
in the kernel log. The caller handles the case when
a NULL pointer is encountered and returns an error.
In the case the wait for command buffer is possible
(because no lock is held as in the OSN case), still wait
until a channel command buffer is available.

In the functions that are registering and unregistering MAC
addresses in the qeth-handled hardware, remove callback functions
that are unnesessary, as only the return code is analyzed.
Translate hardware response codes to semi-standard 'errno'-like
codes for readability.
Add kernel-doc description to the internal API function
qeth_send_control_data().

In commit 5a7baa78851b ("bonding: Advertize vxlan offload features when
supported"), Or Gerlitz added support conditional vxlan offload.
In this patch I also add support for all kind of tunnels,
but we allow a bonding device to not require segmentation,
as it is always better to make this segmentation at the very last stage,
if a particular slave device requires it.
Tested:
Setup a GRE tunnel,
on a physical NIC not having tx-gre-segmentation.
Results on bnx2x are even better, as we no longer have to segment
in software.

Pull x86 fixes from Thomas Gleixner:
"Hopefully the last round of fixes for 3.19
- regression fix for the LDT changes
- regression fix for XEN interrupt handling caused by the APIC
changes
- regression fixes for the PAT changes
- last minute fixes for new the MPX support
- regression fix for 32bit UP
- fix for a long standing relocation issue on 64bit tagged for stable
- functional fix for the Hyper-V clocksource tagged for stable
- downgrade of a pr_err which tends to confuse users
Looks a bit on the large side, but almost half of it are valuable

"A week's worth of fixes for various ARM platforms. Diff wise, the
largest fix is for OMAP to deal with how GIC now registers interrupts
(irq_domain_add_legacy() -> irq_domain_add_linear() changes).
Besides this, a few more renesas platforms needed the GIC instatiation
done for legacy boards. There's also a fix that disables coherency of
mvebu due to issues, and a few other smaller fixes"

- fix potential for dm-cache metadata corruption via stale metadata
buffers being used when switching an inactive cache table to
active; this could occur due to each table having it's own bufio
client rather than sharing the client between tables.
- fix dm-cache target to properly account for discard IO while
suspending otherwise IO quiescing could complete prematurely.
- fix DM core's handling of multiple internal suspends by maintaining
an 'internal_suspend_count' and only resuming the device when this
count drops to zero"

the proper kobject referencing to ensure we release resources at
the right time"

fixed_phy_set_link_update() contains an early check against a NULL
callback pointer, which basically prevents us from removing any
previous callback we may have set. The users of the fp->link_update
callback deal with a NULL callback just fine, so we really want to allow
"removing" a link_update callback to avoid dangling callback pointers
during e.g: module removal.
