====================
here's a bigger pull request for 4.4. The diffstat looks scary as we
created a new directory realtek for all realtek drivers. In the future
I'm planning to create similar directories for all vendors, currently we
just have ath, mediatek and realtek. This change has been in linux-next
for a couple of weeks so it should be safe, but of course you never
know.

There's also a new driver rtl8xxxu for few realtek USB devices. This
just made it to the last linux-next build.

Otherwise there's nothing really special, more info below. If time
permits, and it's ok for you, I'm hoping to send you a one more pull
request this week.

brcmfmac

* using netdev carrier state
* add and rework some cfg80211 callbacks mainly for AP mode
* use devcoredump when triggered by firmware event

realtek

* create new directory drivers/net/wireless/realtek/ for all realtek
  drivers, not visible to users (no kconfig changes etc)
* add rtl8xxxu, a new mac80211 driver for RTL8723AU, RTL8188CU,
  RTL8188RU, RTL8191CU, RTL8192CU and hopefully more in the future

ath10k

* add board 2 API support for automatically choosing correct board file
* data path optimisations
* disable PCI power save for qca988x and QCA99x0 due to interop reasons

wil6210

* BlockAckReq support
* firmware crashdump using devcoredump
* capture all frames with sniffer

      seccomp, ptrace: add support for dumping seccomp filters · f8e529ed
      由 Tycho Andersen 提交于 
      This patch adds support for dumping a process' (classic BPF) seccomp
filters via ptrace.

PTRACE_SECCOMP_GET_FILTER allows the tracer to dump the user's classic BPF
seccomp filters. addr should be an integer which represents the ith seccomp
filter (0 is the most recently installed filter). data should be a struct
sock_filter * with enough room for the ith filter, or NULL, in which case
the filter is not saved. The return value for this command is the number of
BPF instructions the program represents, or negative in the case of errors.
Command specific errors are ENOENT: which indicates that there is no ith
filter in this seccomp tree, and EMEDIUMTYPE, which indicates that the ith
filter was not installed as a classic BPF filter.

A caveat with this approach is that there is no way to get explicitly at
the heirarchy of seccomp filters, and users need to memcmp() filters to
decide which are inherited. This means that a task which installs two of
the same filter can potentially confuse users of this interface.

v2: * make save_orig const
    * check that the orig_prog exists (not necessary right now, but when
       grows eBPF support it will be)
    * s/n/filter_off and make it an unsigned long to match ptrace
    * count "down" the tree instead of "up" when passing a filter offset

v3: * don't take the current task's lock for inspecting its seccomp mode
    * use a 0x42** constant for the ptrace command value

v4: * don't copy to userspace while holding spinlocks

v5: * add another condition to WARN_ON

v6: * rebase on net-next

      Robert Shearman says:

====================
mpls: mulipath improvements

Two improvements to the recently added mpls multipath support. The
first is a fix for missing initialisation the nexthop address length
for the v4 and v6 explicit null label routes, and the second is to
reduce the amount of memory used by mpls routes by changing the way
the via addresses are stored.

      mpls: reduce memory usage of routes · cf4b24f0
      由 Robert Shearman 提交于 
      Nexthops for MPLS routes have a via address field sized for the
largest via address that is expected, which is 32 bytes. This means
that in the most common case of having ipv4 via addresses, 28 bytes of
memory more than required are used per nexthop. In the other common
case of an ipv6 nexthop then 16 bytes more than required are
used. With large numbers of MPLS routes this extra memory usage could
start to become significant.

To avoid allocating memory for a maximum length via address when not
all of it is required and to allow for ease of iterating over
nexthops, then the via addresses are changed to be stored in the same
memory block as the route and nexthops, but in an array after the end
of the array of nexthops. New accessors are provided to retrieve a
pointer to the via address.

To allow for O(1) access without having to store a pointer or offset
per nh, the via address for each nexthop is sized according to the
maximum via address for any nexthop in the route, which is stored in a
new route field, rt_max_alen, but this is in an existing hole in
struct mpls_route so it doesn't increase the size of the
structure. Each via address is ensured to be aligned to VIA_ALEN_ALIGN
to account for architectures that don't allow unaligned accesses.
