49e19ec7d3 rxrpc: Add tracepoints to record received packets and end of data_ready
Add two tracepoints:

 (1) Record the RxRPC protocol header of packets retrieved from the UDP
     socket by the data_ready handler.

 (2) Record the outcome of the data_ready handler.

18f1387c7d rxrpc: Update protocol definitions slightly
Update the protocol definitions in include/rxrpc/packet.h slightly:

 (1) Get rid of RXRPC_PROCESS_MAXCALLS as it's redundant (same as
     RXRPC_MAXCALLS).

 (2) In struct rxrpc_jumbo_header, put _rsvd in a union with a field called
     cksum to match struct rxrpc_wire_header.

 (3) Provide RXRPC_JUMBO_SUBPKTLEN which is the total of the amount of data
     in a non-terminal subpacket plus the following secondary header for
     the next packet included in the jumbo packet.

5a42976d4f rxrpc: Add tracepoint for working out where aborts happen
Add a tracepoint for working out where local aborts happen.  Each
tracepoint call is labelled with a 3-letter code so that they can be
distinguished - and the DATA sequence number is added too where available.

rxrpc_kernel_abort_call() also takes a 3-letter code so that AFS can
indicate the circumstances when it aborts a call.

fff72429c2 rxrpc: Improve the call tracking tracepoint
Improve the call tracking tracepoint by showing more differentiation
between some of the put and get events, including:

  (1) Getting and putting refs for the socket call user ID tree.

  (2) Getting and putting refs for queueing and failing to queue the call
      processor work item.

Note that these aren't necessarily used in this patch, but will be taken
advantage of in future patches.

An enum is added for the event subtype numbers rather than coding them
directly as decimal numbers and a table of 3-letter strings is provided
rather than a sequence of ?: operators.

7e567624dc drm/i2c: tda998x: Register ASoC hdmi-codec and add audio DT binding
Register ASoC HDMI codec for audio functionality and adds device tree
binding for audio configuration.

With the registered HDMI codec the tda998x node can be used like a
regular codec node in ASoC card configurations. HDMI audio info-frame
and audio stream header is generated by the ASoC HDMI codec. The codec
also applies constraints for available sample-rates based on Edid Like
Data from the display. The device tree binding document has been
updated [1].

Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x:
Add support of a DT graph of ports"-patch [2]. There may still be some
identical lines left from the original patch and some of the ideas
have come from there.

9bb87c027c The biggest addition is probably the special clock-type for ddr clock
control. While reading that clock is done the normal way from the
 registers, setting it always requires some sort of special handling
 to let the system survive this addition.
 
 As the commit message explains, there are currently 3 handling-types
 known. General SRAM-based code on rk3288 and before (which is waiting
 essentially for the PIE support that is currently being worked on),
 SCPI-based clk setting on the rk3368 through a coprocessor, which we
 might support once the support for legacy scpi-variants has matured
 and now on the rk3399 (and probably later) using a dcf controller that
 is controlled from the arm-trusted-firmware and gets accessed through
 firmware calls from the kernel. This is the variant we currently
 support, but the clock type is made to support the other variants in
 the future as well.
 
 Apart from that slightly bigger chunk, we have a mix of PLL rates,
 clock-ids and flags mainly for the rk3399.
 
 And interestingly an iomap fix for the legacy gate driver, where I
 hopefully could deter the submitter from actually using that in any
 new works.

5a56a0b3a4 net: Don't delete routes in different VRFs
When deleting an IP address from an interface, there is a clean-up of
routes which refer to this local address. However, there was no check to
see that the VRF matched. This meant that deletion wasn't confined to
the VRF it should have been.

To solve this, a new field has been added to fib_info to hold a table
id. When removing fib entries corresponding to a local ip address, this
table id is also used in the comparison.

The table id is populated when the fib_info is created. This was already
done in some places, but not in ip_rt_ioctl(). This has now been fixed.

====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for your net-next
tree.  Most relevant updates are the removal of per-conntrack timers to
use a workqueue/garbage collection approach instead from Florian
Westphal, the hash and numgen expression for nf_tables from Laura
Garcia, updates on nf_tables hash set to honor the NLM_F_EXCL flag,
removal of ip_conntrack sysctl and many other incremental updates on our
Netfilter codebase.

More specifically, they are:

1) Retrieve only 4 bytes to fetch ports in case of non-linear skb
   transport area in dccp, sctp, tcp, udp and udplite protocol
   conntrackers, from Gao Feng.

2) Missing whitespace on error message in physdev match, from Hangbin Liu.

3) Skip redundant IPv4 checksum calculation in nf_dup_ipv4, from Liping Zhang.

4) Add nf_ct_expires() helper function and use it, from Florian Westphal.

5) Replace opencoded nf_ct_kill() call in IPVS conntrack support, also
   from Florian.

6) Rename nf_tables set implementation to nft_set_{name}.c

7) Introduce the hash expression to allow arbitrary hashing of selector
   concatenations, from Laura Garcia Liebana.

8) Remove ip_conntrack sysctl backward compatibility code, this code has
   been around for long time already, and we have two interfaces to do
   this already: nf_conntrack sysctl and ctnetlink.

9) Use nf_conntrack_get_ht() helper function whenever possible, instead
   of opencoding fetch of hashtable pointer and size, patch from Liping Zhang.

10) Add quota expression for nf_tables.

11) Add number generator expression for nf_tables, this supports
    incremental and random generators that can be combined with maps,
    very useful for load balancing purpose, again from Laura Garcia Liebana.

12) Fix a typo in a debug message in FTP conntrack helper, from Colin Ian King.

13) Introduce a nft_chain_parse_hook() helper function to parse chain hook
    configuration, this is used by a follow up patch to perform better chain
    update validation.

14) Add rhashtable_lookup_get_insert_key() to rhashtable and use it from the
    nft_set_hash implementation to honor the NLM_F_EXCL flag.

15) Missing nulls check in nf_conntrack from nf_conntrack_tuple_taken(),
    patch from Florian Westphal.

16) Don't use the DYING bit to know if the conntrack event has been already
    delivered, instead a state variable to track event re-delivery
    states, also from Florian.

17) Remove the per-conntrack timer, use the workqueue approach that was
    discussed during the NFWS, from Florian Westphal.

18) Use the netlink conntrack table dump path to kill stale entries,
    again from Florian.

19) Add a garbage collector to get rid of stale conntracks, from
    Florian.

20) Reschedule garbage collector if eviction rate is high.

21) Get rid of the __nf_ct_kill_acct() helper.

22) Use ARPHRD_ETHER instead of hardcoded 1 from ARP logger.

23) Make nf_log_set() interface assertive on unsupported families.

6296c41259 SCSI fixes on 20160906
This is really three fixes, but the SES one comes in a bundle of three
 (making the replacement API available properly, using it and removing
 the non-working one).  The SES problem causes an oops on hpsa devices
 because they attach virtual disks to the host which aren't SAS
 attached (the replacement API ignores them).  The other two fixes are
 fairly minor: the sense key one means we actually resolve a newly
 added sense key and the RDAC device blacklisting is needed to prevent
 us annoying the universal XPORT lun of various RDAC arrays.

21b6657ef4 remoteproc: core: transform struct fw_rsc_vdev_vring reserved field in pa
In current implementation, struct fw_rsc_vdev_vring which describes
vring resource in firmware resource table owns only device address,
because it assumes that host is responsible of vring allocation and
only device address is needed by coprocessor.
But if vrings need to be fixed in system memory map for any reasons
(security, SoC charactieristics...), physical address is needed exatly
identified the memory chunck by host.

For that let's transform reserved field of struct fw_rsc_vdev_vring
to pa (physical address).

68e694dcef powerpc/powermac: Convert to hotplug state machine
Install the callbacks via the state machine.
I assume here that the powermac has two CPUs and so only one can go up
or down at a time. The variable smp_core99_host_open is here to ensure
that we do not try to open or close the i2c host twice if something goes
wrong and we invoke the prepare or online callback twice due to
rollback.

b828f96021 ARM: 8611/1: l2x0: add PMU support
The L2C-220 (AKA L220) and L2C-310 (AKA PL310) cache controllers feature
a Performance Monitoring Unit (PMU), which can be useful for tuning
and/or debugging. This hardware is always present and the relevant
registers are accessible to non-secure accesses. Thus, no special
firmware interface is necessary.

This patch adds support for the PMU, plugging into the usual perf
infrastructure. The overflow interrupt is not always available (e.g. on
RealView PBX A9 it is not wired up at all), and the hardware counters
saturate, so the driver does not make use of this. Instead, the driver
periodically polls and reset counters as required to avoid losing
events due to saturation.
