Commit 66e63ffbc04706568d8789cbb00eaa8ddbcae648 ("mv643xx_eth:
implement ->set_rx_mode()") cleaned up mv643xx_eth's multicast filter
programming, but broke it as well.
The non-special multicast filter table (for multicast addresses that
are not of the form 01:00:5e:00:00:xx) consists of 256 hash table
buckets organised as 64 32-bit words, where the 'accept' bits are
in the LSB of each byte, so in bits 24 16 8 0 of each 32-bit word.
The old code got this right, but the referenced commit broke this by
using bits 3 2 1 0 instead. This commit fixes this up.

net: Fix data corruption when splicing from sockets.
The trick in socket splicing where we try to convert the skb->data
into a page based reference using virt_to_page() does not work so
well.
The idea is to pass the virt_to_page() reference via the pipe
buffer, and refcount the buffer using a SKB reference.
But if we are splicing from a socket to a socket (via sendpage)
this doesn't work.
The from side processing will grab the page (and SKB) references.
The sendpage() calls will grab page references only, return, and
then the from side processing completes and drops the SKB ref.
The page based reference to skb->data is not enough to keep the
kmalloc() buffer backing it from being reused. Yet, that is
all that the socket send side has at this point.
This leads to data corruption if the skb->data buffer is reused
by SLAB before the send side socket actually gets the TX packet
out to the device.
The fix employed here is to simply allocate a page and copy the
skb->data bytes into that page.
This will hurt performance, but there is no clear way to fix this
properly without a copy at the present time, and it is important
to get rid of the data corruption.
With fixes from Herbert Xu.

tg3: Fix firmware loading
This patch modifies how the tg3 driver handles device firmware.
The patch starts by consolidating David Woodhouse's earlier patch under
the same name. Specifically, the patch moves the request_firmware call
into a separate tg3_request_firmware() function and calls that function
from tg3_open() rather than tg3_init_one().
The patch then goes on to limit the number of devices that will make
request_firmware calls. The original firmware patch unnecessarily
requested TSO firmware for devices that did not need it. This patch
reduces the set of devices making TSO firmware patches to approximately
the following device set : 5703, 5704, and 5705.
Finally, the patch reduces the effects of a request_firmware() failure.
For those devices that are requesting TSO firmware, the driver will turn
off the TSO capability. If TSO firmware becomes available at a later
time, the device can be closed and then opened again to reacquire the
TSO capability.

drm: initial KMS config fixes
When mode setting is first initialized, the driver will call into
drm_helper_initial_config() to set up an initial output and framebuffer
configuration. This routine is responsible for probing the available
connectors, encoders, and crtcs, looking for modes and putting together
something reasonable (where reasonable is defined as "allows kernel
messages to be visible on as many displays as possible").
However, the code was a bit too aggressive in setting default modes when
none were found on a given connector. Even if some connectors had modes,
any connectors found lacking modes would have the default 800x600 mode added
to their mode list, which in some cases could cause problems later down the
line. In my case, the LVDS was perfectly available, but the initial config
code added 800x600 modes to both of the detected but unavailable HDMI
connectors (which are on my non-existent docking station). This ended up
preventing later code from setting a mode on my LVDS, which is bad.
This patch fixes that behavior by making the initial config code walk
through the connectors first, counting the available modes, before it decides
to add any default modes to a possibly connected output. It also fixes the
logic in drm_target_preferred() that was causing zeroed out modes to be set
as the preferred mode for a given connector, even if no modes were available.

For irq based hvc_console backends the tty->low_latency must be set to 0,
because the tty_flip_buffer_push() function must not be called from IRQ context
(see drivers/char/tty_buffer.c).
For polled backends, the low_latency setting causes the bug trace below, because
tty_flip_buffer_push() is called within an atomic context and subsequent calls
might sleep due to mutex_lock.

powerpc: Get the number of SLBs from "slb-size" property
The PAPR says that the property for specifying the number of SLBs should
be called "slb-size". We currently only look for "ibm,slb-size" because
this is what firmware actually presents.
This patch makes us look for the "slb-size" property as well and in
preference to the "ibm,slb-size". This should future proof us if
firmware changes to match PAPR.

However, the current config dependencies allow NET_9P_RDMA to be selected

on INFINIBAND_ADDR_TRANS to disallow NET_9P_RDMA in this case.
