Currently, a PF does not restrict its VF interface from enabling vlan
promiscuous mode. This breaks vlan isolation when a vlan
(transparent tagging) is configured on a VF.
This patch fixes this problem by disabling the vlan promisc capability
for VFs.

On a MIPS Malta board, tons of fifo underflow errors have been observed
when using u-boot as bootloader instead of YAMON. The reason for that
is that YAMON used to set the pcnet device to SRAM mode but u-boot does
not. As a result, the default Tx threshold (64 bytes) is now too small to
keep the fifo relatively used and it can result to Tx fifo underflow errors.
As a result of which, it's best to setup the SRAM on supported controllers
so we can always use the NOUFLO bit.

On sun4i-a10, when GPIOs are configured as external interrupt the value for
them in the data register does not seem to get updated, so set their mux to
input (and restore afterwards) when reading the pin.
Missed edges seem to be buffered, so this does not introduce a race
condition.
I've also tested this on sun5i-a13 and sun7i-a20 and those do not seem to
be affected, the input value representation in the data register does seem
to correctly get updated to the actual pin value while in irq mode there.

The gpiochip_lock_as_irq call can fail and return an error,
while the irq_startup is not expected to fail (returns an
unsigned int which is not checked by irq core code).
irq_request/release_resources functions have been created
to address this problem.
Move gpiochip_lock/unlock_as_irq calls into
irq_request/release_resources functions to prevent using a
gpio as an irq if the gpiochip_lock_as_irq call failed.

The commit breaks the legacy platforms, ie. these not using device-tree,
and setting up the interrupt resources with a flag to activate edge
detection. The issue was found on the zylonite platform.
The reason is that zylonite uses platform resources to pass the interrupt number
and the irq flags (here IORESOURCE_IRQ_HIGHEDGE). It expects the driver to
request the irq with these flags, which in turn setups the irq as high edge
triggered.
After the patch, this was supposed to be taken care of with :
irq_resflags = irqd_get_trigger_type(irq_get_irq_data(ndev->irq));
But irq_resflags is 0 for legacy platforms, while for example in
arch/arm/mach-pxa/zylonite.c, in struct resource smc91x_resources[] the
irq flag is specified. This breaks zylonite because the interrupt is not
setup as triggered, and hardware doesn't provide interrupts.

This is fixed by both fixing the reference counting directly and by
making the resume code skip enables it doesn't need to do. We could
skip the change in the resume code but it's a very simple change and
adds extra robustness against problems in other drivers"

Going over the virtio mmio code, I noticed that it doesn't correctly
access modern device config values using "natural" accessors: it uses
readb to get/set them byte by byte, while the virtio 1.0 spec explicitly states:
4.2.2.2 Driver Requirements: MMIO Device Register Layout
...
The driver MUST only use 32 bit wide and aligned reads and writes to
access the control registers described in table 4.1.
For the device-specific configuration space, the driver MUST use
8 bit wide accesses for 8 bit wide fields, 16 bit wide and aligned
accesses for 16 bit wide fields and 32 bit wide and aligned accesses for
32 and 64 bit wide fields.
Borrow code from virtio_pci_modern to do this correctly.

E1x chips (57710, 57711(E)) have no support for encapsulation
offload. bnx2x incorrectly advertises the support as available.
Setting of those features is conditional on "!CHIP_IS_E1x(bp)", but
the bp struct is not initialized yet at this point and consequently
any chip passes the check.
The check must use the "chip_is_e1x" local variable instead to work
correctly.

Pull clock framework fixes from Michael Turquette:
"The clk fixes for 4.0-rc4 comprise three themes.
First are the usual driver fixes for new regressions since v3.19.
Second are fixes to the common clock divider type caused by recent
changes to how we round clock rates. This affects many clock drivers
that use this common code.
Finally there are fixes for drivers that improperly compared struct
clk pointers (drivers must not deref these pointers). While some of
these drivers have done this for a long time, this did not cause a
problem until we started generating unique struct clk pointers for
every consumer. A new function, clk_is_match was introduced to get
these drivers working again and they are fixed up to no longer deref
the pointers themselves"

The linux kernel has supported the TiVo Slide remote control for some time, but
does not recognize the USB ID of the newer Slide Pro. This patch adds the
missing data structures so the newer remote will be recognized by the driver,
thereby allowing the TiVo, LiveTV, and Thumbs Up/Down buttons to be
mapped with a hwdb file.

A number of tx queue wake-up events went missing due to the
outlined scenario below. Start state is a pool of 16 tx URBs,
active tx_urbs count = 15, with the netdev tx queue open.
CPU #1 [softirq] CPU #2 [softirq]
start_xmit() tx_acknowledge()
................ ................
atomic_inc(&tx_urbs);
if (atomic_read(&tx_urbs) >= 16) {
-->
atomic_dec(&tx_urbs);
netif_wake_queue();
return;
<--
netif_stop_queue();
}
At the end, the correct state expected is a 15 tx_urbs count
value with the tx queue state _open_. Due to the race, we get
the same tx_urbs value but with the tx queue state _stopped_.
The wake-up event is completely lost.
Thus avoid hand-rolled concurrency mechanisms and use a proper
lock for contexts and tx queue protection.

This reverts commit 2b995f63987013bacde99168218f9c7b252bdcf1.
Панов Андрей reported the following regression:
"Commit 2b995f63987013bacde99168218f9c7b252bdcf1 in 4.0.0-rc3 introduces a
nasty bug in transmit, corrupting packets.
To reproduce:
$ dd if=/dev/zero of=zeros bs=1M count=20
$ md5sum -b zeros
8f4e33f3dc3e414ff94e5fb6905cba8c *zeros
This checksum is correct.
Copy file "zeros" to another host with NFS, and it gets corrupted, checksum is
changed.
File should be big, small amounts of transmit isn't affected.
I use an i.MX6 Quad board.
If this commit is reverted, all works fine."

commit dfd8645ea1bd9127 wrongly assumes that VXLAN_VDI_MASK includes
eight lower order reserved bits of VNI field that are using for remote
checksum offload.
Right now, when VNI number greater then 0xffff, vxlan_udp_encap_recv()
will always return with 'bad_flag' error, reducing the usable vni range
from 0..16777215 to 0..65535. Also, it doesn't really check whether RCO
bits processed or not.
Fix it by adding new VNI mask which has all 32 bits of VNI field:
24 bits for id and 8 bits for other usage.

virtio spec requires that all drivers set DRIVER_OK
before using devices. While rpmsg isn't yet
included in the virtio 1 spec, previous spec versions
also required this.
virtio rpmsg violates this rule: is calls kick
before setting DRIVER_OK.
The fix isn't trivial since simply calling virtio_device_ready earlier
would mean we might get an interrupt in parallel with adding buffers.
Instead, split kick out to prepare+notify calls. prepare before
virtio_device_ready - when we know we won't get interrupts. notify right
afterwards.
