c02b73c943 clk: ti: dflt: remove redundant unlikely
Commit 7aba4f5201 ("clk: ti: dflt: fix enable_reg validity check")
fixed a validation check by using an IS_ERR() macro within the
existing unlikely expression, but IS_ERR() macro already has an
unlikely inside it, so get rid of the redundant unlikely macro
from the validation check.

ab98e20af5 This is first big chunk of Rockchip clock-related changes for 4.7.
Main change is probably the added support for the new rk3399 soc
 and necessary infrastructure changes surrounding it.
 
 The biggest chunk is probably that clock code is now able to
 handle multiple clock providers in one system, as the rk3399
 has two of those. A general one and another smaller one in a
 separate power domain. The rk3399 also uses another new pll type.
 Thankfully it just fits nicely into our current structure.
 It also needs some parts like the cpuclk mux parameters to be
 a bit more flexible and an new fractional divider subtype without
 gate.
 
 Apart from this big change we have some more fixes and removal
 of forgotten variables.

Pull block fixes from Jens Axboe:
 "A few fixes for the current series. This contains:

   - Two fixes for NVMe:

     One fixes a reset race that can be triggered by repeated
     insert/removal of the module.

     The other fixes an issue on some platforms, where we get probe
     timeouts since legacy interrupts isn't working.  This used not to
     be a problem since we had the worker thread poll for completions,
     but since that was killed off, it means those poor souls can't
     successfully probe their NVMe device.  Use a proper IRQ check and
     probe (msi-x -> msi ->legacy), like most other drivers to work
     around this.  Both from Keith.

   - A loop corruption issue with offset in iters, from Ming Lei.

   - A fix for not having the partition stat per cpu ref count
     initialized before sending out the KOBJ_ADD, which could cause user
     space to access the counter prior to initialization.  Also from
     Ming Lei.

9e52cec04f clk: Add clk_composite_set_rate_and_parent
When changing the clock-rate, currently a new parent is set first and a
divider adapted thereafter. This may result in the clock-rate overflowing
its target rate for a short time if the new parent has a higher rate than
the old parent.

While this often doesn't produce negative effects, it can affect components
in a voltage-scaling environment, like the GPU on the rk3399 socs, where
the voltage than simply is to low for the temporarily to high clock rate.

For general clock hirarchies this may need more extensive adaptions to
the common clock-framework, but at least for composite clocks having
both parent and rate settings it is easy to create a short-term solution to
make sure the clock-rate does not overflow the target.

4e811b1e11 Merge branch 'sctp-diag'
Xin Long says:

====================
sctp: support sctp_diag in kernel

This patchset will add sctp_diag module to implement diag interface on
sctp in kernel.

For a listening sctp endpoint, we will just dump it's ep info.
For a sctp connection, we will the assoc info and it's ep info.

The ss dump will looks like:

[iproute2]# ./misc/ss --sctp  -n -l
State      Recv-Q Send-Q   Local Address:Port       Peer Address:Port
LISTEN     0      128      172.16.254.254:8888      *:*

LISTEN     0      5        127.0.0.1:1234           *:*
  - ESTAB  0      0        127.0.0.1%lo:1234        127.0.0.1:4321
LISTEN     0      128      172.16.254.254:8888      *:*
  - ESTAB  0      0        172.16.254.254%eth1:8888 172.16.253.253:8888
  - ESTAB  0      0        172.16.254.254%eth1:8888 172.16.1.1:8888
  - ESTAB  0      0        172.16.254.254%eth1:8888 172.16.1.2:8888
  - ESTAB  0      0        172.16.254.254%eth1:8888 172.16.2.1:8888
  - ESTAB  0      0        172.16.254.254%eth1:8888 172.16.2.2:8888
  - ESTAB  0      0        172.16.254.254%eth1:8888 172.16.3.1:8888
  - ESTAB  0      0        172.16.254.254%eth1:8888 172.16.3.2:8888
LISTEN     0      0        127.0.0.1:4321           *:*
  - ESTAB  0      0        127.0.0.1%lo:4321        127.0.0.1:1234

The entries with '- ESTAB' are the assocs, some of them may belong to
the same endpoint. So we will dump the parent endpoint first, like the
entry with 'LISTEN'. then dump the assocs. ep and assocs entries will
be dumped in right order so that ss can show them in tree format easily.

Besides, this patchset also simplifies sctp proc codes, cause it has
some similar codes with sctp diag in sctp transport traversal.

v1->v2:
  1. inet_diag_get_handler needs to return it as const.
  2. merge 5/7 into 2/7 of v1.

v2->v3:
  do some improvements and fixes in patch 1-4, see the details in
  each patch's comment.

53fa10369c sctp: fix some rhashtable functions using in sctp proc/diag
When rhashtable_walk_init return err, no release function should be
called, and when rhashtable_walk_start return err, we should only invoke
rhashtable_walk_exit to release the source.

But now when sctp_transport_walk_start return err, we just call
rhashtable_walk_stop/exit, and never care about if rhashtable_walk_init
or start return err, which is so bad.

We will fix it by calling rhashtable_walk_exit if rhashtable_walk_start
return err in sctp_transport_walk_start, and if sctp_transport_walk_start
return err, we do not need to call sctp_transport_walk_stop any more.

For sctp proc, we will use 'iter->start_fail' to decide if we will call
rhashtable_walk_stop/exit.

8f840e47f1 sctp: add the sctp_diag.c file
This one will implement all the interface of inet_diag, inet_diag_handler.
which includes sctp_diag_dump, sctp_diag_dump_one and sctp_diag_get_info.

It will work as a module, and register inet_diag_handler when loading.

v2->v3:
- fix the mistake in inet_assoc_attr_size().

- change inet_diag_msg_laddrs_fill() name to inet_diag_msg_sctpladdrs_fill.

- change inet_diag_msg_paddrs_fill() name to inet_diag_msg_sctpaddrs_fill.

- add inet_diag_msg_sctpinfo_fill() to make asoc/ep fill code clearer.

- add inet_diag_msg_sctpasoc_fill() to make asoc fill code clearer.

- merge inet_asoc_diag_fill() and inet_ep_diag_fill() to
  inet_sctp_diag_fill().

- call sctp_diag_get_info() directly, instead by handler, cause the caller
  is in the same file with it.

- call lock_sock in sctp_tsp_dump_one() to make sure we call get sctp info
  safely.

- after lock_sock(sk), we should check sk != assoc->base.sk.

- change mem[SK_MEMINFO_WMEM_ALLOC] to asoc->sndbuf_used for asoc dump when
  asoc->ep->sndbuf_policy is set. don't use INET_DIAG_MEMINFO attr any more.

cb2050a7b8 sctp: export some functions for sctp_diag in inet_diag
inet_diag_msg_common_fill is used to fill the diag msg common info,
we need to use it in sctp_diag as well, so export it.

inet_diag_msg_attrs_fill is used to fill some common attrs info between
sctp diag and tcp diag.

v2->v3:
- do not need to define and export inet_diag_get_handler any more.
  cause all the functions in it are in sctp_diag.ko, we just call
  them in sctp_diag.ko.

- add inet_diag_msg_attrs_fill to make codes clear.

626d16f50f sctp: export some apis or variables for sctp_diag and reuse some for proc
For some main variables in sctp.ko, we couldn't export it to other modules,
so we have to define some api to access them.

It will include sctp transport and endpoint's traversal.

There are some transport traversal functions for sctp_diag, we can also
use it for sctp_proc. cause they have the similar situation to traversal
transport.

v2->v3:
- rhashtable_walk_init need the parameter gfp, because of recent upstrem

52c52a61a3 sctp: add sctp_info dump api for sctp_diag
sctp_diag will dump some important details of sctp's assoc or ep, we use
sctp_info to describe them,  sctp_get_sctp_info to get them, and export
it to sctp_diag.ko.

v2->v3:
- we will not use list_for_each_safe in sctp_get_sctp_info, cause
  all the callers of it will use lock_sock.

- fix the holes in struct sctp_info with __reserved* field.
  because sctp_diag is a new feature, and sctp_info is just for now,
  it may be changed in the future.

311b21774f sctp: simplify sk_receive_queue locking
SCTP already serializes access to rcvbuf through its sock lock:
sctp_recvmsg takes it right in the start and release at the end, while
rx path will also take the lock before doing any socket processing. On
sctp_rcv() it will check if there is an user using the socket and, if
there is, it will queue incoming packets to the backlog. The backlog
processing will do the same. Even timers will do such check and
re-schedule if an user is using the socket.

Simplifying this will allow us to remove sctp_skb_list_tail and get ride
of some expensive lockings.  The lists that it is used on are also
mangled with functions like __skb_queue_tail and __skb_unlink in the
same context, like on sctp_ulpq_tail_event() and sctp_clear_pd().
sctp_close() will also purge those while using only the sock lock.

Therefore the lockings performed by sctp_skb_list_tail() are not
necessary. This patch removes this function and replaces its calls with
just skb_queue_splice_tail_init() instead.

The biggest gain is at sctp_ulpq_tail_event(), because the events always
contain a list, even if it's queueing a single skb and this was
triggering expensive calls to spin_lock_irqsave/_irqrestore for every
data chunk received.

As SCTP will deliver each data chunk on a corresponding recvmsg, the
more effective the change will be.

====================
mlx5_core: mlx5_ifc updates

This series include mlx5_core updates for both net-next and rdma
trees for 4.7 kernel cycle. This is the only shared code planned
for 4.7 between rdma and net trees. Hopefully, this will prevent
future conflicts when merging between ib-next and net-next once
4.7 cycle is over and merge window is opened.

Both Mellanox rdma and net submissions will proceed once this series
is applied into both trees.

Future shared code will be sent to both maintainers as pull requests
from Mellanox's kernel.org tree.

We have included all the maintainers of respective drivers.
Kindly review the change and let us know in case of any review comments.

This patch will do code optmization for task management functions.
Below are key changes:

1. Remove reset_device hook as it was not being used and driver was
setting this to NULL.

2. Create wrapper functions for task abort and target reset and inside
   these functions adapter specific calls be made. e.g. fusion adapters
   support task abort and target reset so task abort and target reset
   should be issued to fusion adapters only and for MFI adapters, print
   a message saying feature not supported.

64d0b8e4a6 megaraid_sas: call ISR function to clean up pending replies in OCR path
In OCR path, before calling chip reset calls function
megasas_wait_for_outstanding_fusion to check reason for OCR. In case of
firmware FAULT initiated OCR and DCMD timeout initiated timeout, driver
will clear any outstanding reply (yet to be processed by driver) in
reply queues before going for chip reset. This code is added to handle a
scenario when IO timeout initiated adapter reset and management
application initiated adapter reset (by sending command to FAULT
firmware) happens simultaneously since adapter reset function is
safe-guarded by reset_mutex so only thread will be doing controller
reset. Consider IO timeout thread gets mutex and proceeds with adapter
reset process after disabling interrupts and by the time management
application has fired command to firmware to do adapter reset and the
same command is completed by firmware but since interrupts are disabled,
driver will not get completion and the same command will be in
outstanding/pending commands list of driver and refires same command
from IO timeout thread after chip reset which will again FAULT firmware
and eventually causes kill adapter.
