cdaa898b5e staging/easycap: kill telltale logic
This reason for this feature was

'some versions of the videodev module overwrite the data which has
been written by the call to usb_set_intfdata() in easycap_usb_probe(),
replacing it with a pointer to the embedded v4l2_device structure.
to detect this, the string in the easycap.telltale[] buffer is checked.'

The upstream version of v4l2_device_register sets driver data
only when it wasn't already set, therefore this is not needed

b49c78d482 x86, reboot: Acer Aspire One A110 reboot quirk

my Acer Aspire One hangs on reboot.  It appears that its ACPI method
for rebooting is broken.  The attached patch adds a quirk so that the
machine will reboot via the BIOS.

[ hpa: verified that the ACPI control on this machine is just plain broken. ]

5318d809d7 vmxnet3: fix starving rx ring whenoc_skb kb fails
If the rx ring is completely empty, then the device may never fire an rx
interrupt. Unfortunately, the rx interrupt is what triggers populating the
rx ring with fresh buffers, so this will cause networking to lock up.

This patch replenishes the skb in recv descriptor as soon as it is
peeled off while processing rx completions. If the skb/buffer
allocation fails, existing one is recycled and the packet in hand is
dropped. This way none of the RX desc is ever left empty, thus avoiding
starvation

44661462ee bridge: Always flood broadcast packets
As is_multicast_ether_addr returns true on broadcast packets as
well, we need to explicitly exclude broadcast packets so that
they're always flooded.  This wasn't an issue before as broadcast
packets were considered to be an unregistered multicast group,
which were always flooded.  However, as we now only flood such
packets to router ports, this is no longer acceptable.

0371d3f7e8 ARM: move memory layout sanity checking before meminfo initialization
Ensure that the meminfo array is sanity checked before we pass the
memory to memblock.  This helps to ensure that memblock and meminfo
agree on the dimensions of memory, especially when more memory is
passed than the kernel can deal with.

73e6cdcf47 b43: Add RX side DMA memory barrier
This adds a memory barrier to ensure the writes to the ring memory
are committed before the DMA ring pointer is updated.
We do a similar thing on the TX side already.
