Avoid overlapping register regions by making the initial blklen of a new
node 1. If a register write occurs to a yet uncached register, that is
lower than but near an existing node's base_reg, a new node is created
and it's blklen is set to an arbitrary value (sizeof(*rbnode)). That may
cause this node to overlap with another node. Those nodes should be merged,
but this merge doesn't happen yet, so this patch at least makes the initial
blklen small enough to avoid hitting the wrong node, which may otherwise
lead to severe breakage.

my earlier patch "mac80211: change IBSS channel state to chandef"
created a regression by ignoring the channel parameter in
__ieee80211_sta_join_ibss, which breaks IBSS channel selection. This
patch fixes this situation by using the right channel and adopting the
selected bandwidth mode.

commit 385904f819e3 ('sfc: Don't use
efx_filter_{build,hash,increment}() for default MAC filters') used the
wrong name to find the index of default RX MAC filters at insertion/
update time. This could result in memory corruption and would in any
case silently fail to update the filter.

It's not allowed to clear masks of a cpuset if there're tasks in it,
but it's broken:
# mkdir /cgroup/sub
# echo 0 > /cgroup/sub/cpuset.cpus
# echo 0 > /cgroup/sub/cpuset.mems
# echo $$ > /cgroup/sub/tasks
# echo > /cgroup/sub/cpuset.cpus
(should fail)

Currently the topology code computes cpu capacity and stores it in
the list along with hwid(which is MPIDR) as it parses the CPU nodes
in the device tree. This is required as it needs to be mapped to the
logical CPU later.
Since the CPU device nodes can be retrieved in the logical ordering
using DT/OF helpers, its possible to store cpu_capacity also in logical
ordering and avoid storing hwid for each entry.
This patch removes hwid by making use of of_get_cpu_node.

CPUs are also registered as devices but the of_node in these cpu
devices are not initialized. Currently different drivers requiring
to access cpu device node are parsing the nodes themselves and
initialising the of_node in cpu device.
The of_node in all the cpu devices needs to be initialized properly
and at one place. The best place to update this is CPU subsystem
driver when registering the cpu devices.
The OF/DT core library now provides of_get_cpu_node to retrieve a cpu
device node for a given logical index by abstracting the architecture
specific details.
This patch uses of_get_cpu_node to assign of_node when registering the
cpu devices.

OF/DT core library now provides architecture specific hook to match the
logical cpu index with the corresponding physical identifier. Most of the
cpu DT node parsing and initialisation is contained in devtree.c. So it's
better to define ARM specific arch_match_cpu_phys_id there.
This mainly helps to avoid replication of the code doing CPU node parsing
and physical(MPIDR) to logical mapping.

This patch moves the generalized implementation of of_get_cpu_node from
PowerPC to DT core library, thereby adding support for retrieving cpu
node for a given logical cpu index on any architecture.
The CPU subsystem can now use this function to assign of_node in the
cpu device while registering CPUs.
It is recommended to use these helper function only in pre-SMP/early
initialisation stages to retrieve CPU device node pointers in logical
ordering. Once the cpu devices are registered, it can be retrieved easily
from cpu device of_node which avoids unnecessary parsing and matching.

Currently different drivers requiring to access cpu device node are
parsing the device tree themselves. Since the ordering in the DT need
not match the logical cpu ordering, the parsing logic needs to consider
that. However, this has resulted in lots of code duplication and in some
cases even incorrect logic.
It's better to consolidate them by adding support for getting cpu
device node for a given logical cpu index in DT core library. However
logical to physical index mapping can be architecture specific.
PowerPC has it's own implementation to get the cpu node for a given
logical index.
This patch refactors the current implementation of of_get_cpu_node.
This in preparation to move the implementation to DT core library.
It separates out the logical to physical mapping so that a default
matching of the physical id to the logical cpu index can be added
when moved to common code. Architecture specific code can override it.

The VLAN code needs to know the length of the per-port VLAN bitmap to
perform its most basic operations (retrieving VLAN informations, removing
VLANs, forwarding database manipulation, etc). Unfortunately, in the
current implementation we are using a macro that indicates the bitmap
size in longs in places where the size in bits is expected, which in
some cases can cause what appear to be random failures.
Use the correct macro.

====================
Regarding the iwlwifi bits, Johannes says:
"We revert an rfkill bugfix that unfortunately caused more bugs, shuffle
some code to avoid touching the PCIe device before it's enabled and
disconnect if firmware fails to do our bidding. I also have Stanislaw's
fix to not crash in some channel switch scenarios."
As for the mac80211 bits, Johannes says:
"This time, I have one fix from Dan Carpenter for users of
nl80211hdr_put(), and one fix from myself fixing a regression with the
libertas driver."
Along with the above...
Dan Carpenter fixes some incorrectly placed "address of" operators
in hostap that caused copying of junk data.
Jussi Kivilinna corrects zd1201 to use an allocated buffer rather
than the stack for a URB operation.

getsockopt PACKET_STATISTICS returns tp_packets + tp_drops. Commit
ee80fbf301 ("packet: account statistics only in tpacket_stats_u")
cleaned up the getsockopt PACKET_STATISTICS code.
This also changed semantics. Historically, tp_packets included
tp_drops on return. The commit removed the line that adds tp_drops
into tp_packets.
