This contains pretty many small commits covering fairly large range of

- Introduced the helper function and documentation for exposing the
channel map via control API, as discussed in Plumbers; most of PCI
drivers are covered, will follow more drivers later
- Most of drivers have been replaced with the new PM callbacks (if
the bus is supported)
- HD-audio controller got the support of runtime PM and the support of
D3 clock-stop. Also changing the power_save option in sysfs kicks
off immediately to enable / disable the power-save mode.
- Another significant code change in HD-audio is the rewrite of
firmware loading code. Other than that, most of changes in HD-audio
are continued cleanups and standardization for the generic auto
parser and bug fixes (HBR, device-specific fixups), in addition to
the support of channel-map API.
- Addition of ASoC bindings for the compressed API, used by the

- Lots of cleanups and API refreshes for ASoC codec drivers and
DaVinci.
- Conversion of OMAP to dmaengine.
- New machine driver for Wolfson Microelectronics Bells.
- New CODEC driver for Wolfson Microelectronics WM0010.
- Enhancements to the ux500 and wm2000 drivers

Currently, a dummy omap_device is created for the MPU sub-system so
that a device node exists for MPU DVFS. Specifically, for the
association of MPU OPPs to a device node, and so that a voltage
regulator can be mapped to a device node.
For drivers to get a handle to this device node, an OMAP-specific API
has been used. However, the kernel already has device nodes for the
CPU(s) in the system, so we can use those instead of an OMAP-specific
dummy device and then drivers (like OMAP CPUfreq) can use generic
APIs.
To use the existing CPU device nodes, modify the OPP creation and
regulator registration to use the CPU0 device node for registraion.
NOTE: this patch always uses CPU0 as the device node. On all
OMAPs today, MPU DVFS scales all CPUs together, so this will
not be a problem, but this assumption will need to be changed
if independently scalable CPUs are introduced.

Ensure the clock rate that will be used is a valid one before
attempting to scale the voltage. Currently the driver assumes it has
a valid frequency from the OPP table, but boards using different
system oscillators might not have exact matches with the OPP table,
and result in a failing call to clk_set_rate().
This is particularily bad because the voltage may be scaled even
though the frequency is not. This will obviously lead to some
unpredictable behavior, especially if the frequency is high and
the voltage is dropped.

Change de_thread() to use KILLABLE rather than UNINTERRUPTIBLE while
waiting for other threads. The only complication is that we should
clear ->group_exit_task and ->notify_count before we return, and we
should do this under tasklist_lock. -EAGAIN is used to match the
initial signal_group_exit() check/return, it doesn't really matter.
This fixes the (unlikely) race with coredump. de_thread() checks
signal_group_exit() before it starts to kill the subthreads, but this
can't help if another CLONE_VM (but non CLONE_THREAD) task starts the
coredumping after de_thread() unlocks ->siglock. In this case the
killed sub-thread can block in exit_mm() waiting for coredump_finish(),
execing thread waits for that sub-thead, and the coredumping thread
waits for execing thread. Deadlock.

Add flag to request that output route should be

The returned route can be cached as follows:
- in NH exception: because the cached routes are not shared
with other destinations
- in FIB NH: when using gateway because all destinations for
NH share same gateway
As last option, to return rt_gateway!=0 we have to
set DST_NOCACHE.

Add new flag to remember when route is via gateway.
We will use it to allow rt_gateway to contain address of

used or when the NH exception caches per-destination route
without DST_NOCACHE flag, i.e. when routes are not used for
other destinations. By this way we force the neighbour
resolving to work with the routed destination but we
can use different address in the packet, feature needed
for IPVS-DR where original packet for virtual IP is routed
via route to real IP.

After "Cache input routes in fib_info nexthops" (commit
d2d68ba9fe) and "Elide fib_validate_source() completely when possible"
(commit 7a9bc9b81a) we can not send ICMP redirects. It seems we
should not cache the RTCF_DOREDIRECT flag in nh_rth_input because
the same fib_info can be used for traffic that is not redirected,
eg. from other input devices or from sources that are not in same subnet.
As result, we have to disable the caching of RTCF_DOREDIRECT
flag and to force source validation for the case when forwarding
traffic to the input device. If traffic comes from directly connected
source we allow redirection as it was done before both changes.
Avoid setting RTCF_DOREDIRECT if IN_DEV_TX_REDIRECTS
is disabled, this can avoid source address validation and to
help caching the routes.
After the change "Adjust semantics of rt->rt_gateway"
(commit f8126f1d51) we should make sure our ICMP_REDIR_HOST messages
contain daddr instead of 0.0.0.0 when target is directly connected.

improvements for Niagara-4. An 8K page can be cleared in around 600
cycles, because we essentially have a store that behaves like
powerpc's dcbz that we can actually make real use of."
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
Revert strace hiccups fix.
sparc64: Niagara-4 bzero/memset, plus use MRU stores in page copy.
sparc64: Fix strace hiccups when force_successful_syscall() triggers.
sparc64: Rearrange thread info to cheaply clear syscall noerror state.
rx51_si4713_dev is referenced only from rx51_init_si4713.
So the memory for rx51_si4713_dev can be safely freed after init.
Also it references rx51_si4713_board_info which is __initdata_or_module.
fixes the below warning.
WARNING: vmlinux.o(.data+0x30958): Section mismatch in reference from the variable rx51_si4713_dev to the (unknown reference) .init.data:(unknown)
The variable rx51_si4713_dev references
the (unknown reference) __initdata (unknown)
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

memblock_steal tries to reserve physical memory during boot.
When the requested size is not aligned on the section size
then, the remaining memory available for lowmem becomes
unaligned on the section boundary. There is a issue with this,
which is discussed in the thread below.
https://lkml.org/lkml/2012/6/28/112
The final conclusion from the thread seems to
be align the memblock_steal calls on the SECTION boundary.
The issue comes out when LPAE is enabled, where the
section size is 2MB.
Boot tested this on OMAP5 evm with and without LPAE.

read_persistent_clock uses a global variable, use a spinlock to
ensure non-atomic updates to the variable don't overlap and cause
time to move backwards.

It seems IPV6_GRO_CB(skb)->proto can be destroyed in skb_gro_receive()
if a new skb is allocated (to serve as an anchor for frag_list)
We copy NAPI_GRO_CB() only (not the IPV6 specific part) in :
*NAPI_GRO_CB(nskb) = *NAPI_GRO_CB(p);
So we leave IPV6_GRO_CB(nskb)->proto to 0 (fresh skb allocation) instead
of IPPROTO_TCP (6)
ipv6_gro_complete() isnt able to call ops->gro_complete()
[ tcp6_gro_complete() ]
Fix this by moving proto in NAPI_GRO_CB() and getting rid of
IPV6_GRO_CB

6a32e4f9dd made the vlan code skip marking
vlan-tagged frames for not locally configured vlans as PACKET_OTHERHOST if
there was an rx_handler, as the rx_handler could cause the frame to be received
on a different (virtual) vlan-capable interface where that vlan might be
configured.
As rx_handlers do not necessarily return RX_HANDLER_ANOTHER, this could cause
frames for unknown vlans to be delivered to the protocol stack as if they had
been received untagged.
For example, if an ipv6 router advertisement that's tagged for a locally not
configured vlan is received on an interface with macvlan interfaces attached,
macvlan's rx_handler returns RX_HANDLER_PASS after delivering the frame to the
macvlan interfaces, which caused it to be passed to the protocol stack, leading
to ipv6 addresses for the announced prefix being configured even though those
are completely unusable on the underlying interface.
The fix moves marking as PACKET_OTHERHOST after the rx_handler so the
rx_handler, if there is one, sees the frame unchanged, but afterwards,
before the frame is delivered to the protocol stack, it gets marked whether
there is an rx_handler or not.

A few places free skbs using dev_kfree_skb even though they're called
after ieee80211_subif_start_xmit might have cloned it for tracking tx
status. Use ieee80211_free_txskb here to prevent skb leaks.

This patch fixes the following bug:
usb 1-1.1: restart device (8)
BUG: sleeping function called from invalid context at drivers/usb/core/urb.c:654

(tasklet_hi_action+0x84/0xdc)
this only happens if the device is plugged in an USB port,
the driver is loaded but inactive (e.g. the wlan interface
is down). If the device is active everything is fine.
