The patch to convert struct mfc_cache to list_heads (ipv4: ipmr: convert
struct mfc_cache to struct list_head) introduced a bug when adding new
cache entries that don't match any unresolved entries.
The unres queue is searched for a matching entry, which is then resolved.
When no matching entry is present, the iterator points to the head of the
list, but is treated as a matching entry. Use a seperate variable to
indicate that a matching entry was found.

- fix IP DNAT on vlan- or pppoe-encapsulated traffic: The functions
neigh_hh_output() or dst->neighbour->output() overwrite the complete
Ethernet header, although we only need the destination MAC address.
For encapsulated packets, they ended up overwriting the encapsulating
header. The new code copies the Ethernet source MAC address and
protocol number before calling dst->neighbour->output(). The Ethernet
source MAC and protocol number are copied back in place in
br_nf_pre_routing_finish_bridge_slow(). This also makes the IP DNAT
more transparent because in the old scheme the source MAC of the
bridge was copied into the source address in the Ethernet header. We
also let skb->protocol equal ETH_P_IP resp. ETH_P_IPV6 during the
execution of the PF_INET resp. PF_INET6 hooks.
- Speed up IP DNAT by calling neigh_hh_bridge() instead of
neigh_hh_output(): if dst->hh is available, we already know the MAC
address so we can just copy it.

attached please find a patch that adds support for at least the T410s
HDA codec. Most likely it will also add support for the T410 and T510
based models.
The patch was derived from Ideapad support. Support for the laptop's and
docking-station output connectors as well as the docking-station microphone
connector and the laptops internal devices has been tested. Since it has been
developed without a data-sheet available, support for digital outputs and the
laptop's microphone input may well be incorrect.
Microphone mute functionality is not included:
The microphone mute button seems to be reported through thinkpad_acpi key

The Biostar mobo seems to give a wrong DMA position, resulting in
stuttering or skipping sounds on 2.6.34. Since the commit
7b3a177b0d, "ALSA: pcm_lib: fix "something
must be really wrong" condition", makes the position check more strictly,
the DMA position problem is revealed more clearly now.
The fix is to use only LPIB for obtaining the position, i.e. passing
position_fix=1. This patch adds a static quirk to achieve it as default.

This implements support for hardware-managed IRQ balancing as implemented
by SH-X3 cores (presently only hooked up for SH7786, but can probably be
carried over to other SH-X3 cores, too).
CPUs need to specify their distribution register along with the mask
definitions, as these follow the same format. Peripheral IRQs that don't
opt out of balancing will be automatically distributed at the whim of the
hardware block, while each CPU needs to verify whether it is handling the
IRQ or not, especially before clearing the mask.

Trace events are mostly used for tracing and then require not to
be lost when possible. As opposite to hardware events that really
require to trigger after a given sample period, trace events mostly
need to trigger everytime.
It is a frustrating experience to trace with perf and realize we
lost a lot of events because we forgot the "-c 1" option.
Then default sample_period to 1 for trace events but let the user

Checking if a tracing field is an array with a dynamic length
requires to check the field type and seek the "__data_loc"
string that prepends the actual type, as can be found in a trace
event format file:
field:__data_loc char[] name; offset:16; size:4; signed:1;
But we actually use strcmp() to check if the field type fully
matches "__data_loc", which may fail as we trip over the rest of
the type.
To fix this, use strncmp to only check if it starts with
"__data_loc".

The ixgbe driver was setting up 82598 hardware correctly, so that
when promiscuous mode was enabled hardware stripping was turned
off. But on 82599 the logic to disable/enable hardware stripping
is different, and the code was not updated correctly when the
hardware vlan stripping was enabled as default.
This change comprises the creation of two new helper functions
and calling them from the right locations to disable and enable
hardware stripping of vlan tags at appropriate times.
