2f5ff26478 mlx5: Fix naming convention with respect to UARs
This establishes a solid naming conventions for UARs. A UAR (User Access
Region) can have size identical to a system page or can be fixed 4KB
depending on a value queried by firmware. Each UAR always has 4 blue
flame register which are used to post doorbell to send queue. In
addition, a UAR has section used for posting doorbells to CQs or EQs. In
this patch we change names to reflect this conventions.

Saeed Mahameed says:

====================
Mellanox mlx5 core and ODP updates 2017-01-01

The following eleven patches mainly come from Artemy Kovalyov
who expanded mlx5 on-demand-paging (ODP) support. In addition
there are three cleanup patches which don't change any functionality,
but are needed to align codebase prior accepting other patches.

Memory region (MR) in IB can be huge and ODP (on-demand paging)
technique allows to use unpinned memory, which can be consumed and
released on demand. This allows to applications do not pin down
the underlying physical pages of the address space, and save from them
need to track the validity of the mappings.

Rather, the HCA requests the latest translations from the OS when pages
are not present, and the OS invalidates translations which are no longer
valid due to either non-present pages or mapping changes.

In existing ODP implementation applications is needed to register
memory buffers for communication, though registered memory regions
need not have valid mappings at registration time.

This patch set performs the following steps to expand
current ODP implementation:

1. It refactors UMR to support large regions, by introducing generic
   function to perform HCA translation table modifications. This
   function supports both atomic and process contexts and is not limited
   by number of modified entries.

   This function allows to enable reallocated memory regions of
   arbitrary size, so adding MR cache buckets to support up to 16GB MRs.

2. It changes page fault event format and refactor page faults logic
   together with addition of atomic support.

3. It prepares mlx5 core code to support implicit registration with
   simplified and relaxed semantics.

   Implicit ODP semantics allows to applications provide special memory
   key that represents their complete address space. Thus all IO accesses
   referencing to this key (with proper access rights associated with the key)
   wouldn't need not register any virtual address range.

Thanks,
        Artemy, Ilya and Leon

31b95c9bdc net: stmmac: remove unused duplicate property snps,axi_all
For core revision 3.x Address-Aligned Beats is available in two registers.
The DT property snps,aal was created for AAL in the DMA bus register,
which is a read/write bit.
The DT property snps,axi_all was created for AXI_AAL in the AXI bus mode
register, which is a read only bit that reflects the value of AAL in the
DMA bus register.

Since the value of snps,axi_all is never used in the driver,
and since the property was created for a bit that is read only,
it should be safe to remove the property.

e3eef7ee02 qede: Postpone reallocation until NAPI end
During Rx flow driver allocates a replacement buffer each time
it consumes an Rx buffer. Failing to do so, it would consume the
currently processed buffer and re-post it on the ring.
As a result, the Rx ring is always completely full [from driver POV].

We now allow the Rx ring to shorten by doing the re-allocations
at the end of the NAPI run. The only limitation is that we still want to
make sure each time we reallocate that we'd still have sufficient
elements in the Rx ring to guarantee that FW would be able to post
additional data and trigger an interrupt.

e1d32acbcb qed*: Change maximal number of queues
Today qede requests contexts that would suffice for 64 'whole'
combined queues [192 meant for 64 rx, tx and xdp tx queues],
but registers netdev and limits the number of queues based on
information received by qed. In turn, qed doesn't take context
into account when informing qede how many queues it can support.

This would lead to a configuration problem in case user tries
configuring >64 combined queues to interface [or >96 in case
xdp isn't enabled]. Since we don't have a mangement firware
that actually provides so many interrupt lines to a single
device we're currently safe but that's about to change soon.

The new maximum is hence changed:
  - For RoCE devices, the limit would remain 64.
  - For non-RoCE devices, the limit might be higher [depending
    on the actual configuration of the device].
qed would start enforcing that limit in both scenarios.

7bb387c5ab net: Allow IP_MULTICAST_IF to set index to L3 slave
IP_MULTICAST_IF fails if sk_bound_dev_if is already set and the new index
does not match it. e.g.,

    ntpd[15381]: setsockopt IP_MULTICAST_IF 192.168.1.23 fails: Invalid argument

Relax the check in setsockopt to allow setting mc_index to an L3 slave if
sk_bound_dev_if points to an L3 master.

Make a similar change for IPv6. In this case change the device lookup to
take the rcu_read_lock avoiding a refcnt. The rcu lock is also needed for
the lookup of a potential L3 master device.

This really only silences a setsockopt failure since uses of mc_index are
secondary to sk_bound_dev_if if it is set. In both cases, if either index
is an L3 slave or master, lookups are directed to the same FIB table so
relaxing the check at setsockopt time causes no harm.

Patch is based on a suggested change by Darwin for a problem noted in
their code base.

40b368af4b rtlwifi: Fix alignment issues
The addresses of Wlan NIC registers are natural alignment, but some
drivers have bugs. These are evident on platforms that need natural
alignment to access registers.  This change contains the following:
 1. Function _rtl8821ae_dbi_read() is used to read one byte from DBI,
    thus it should use rtl_read_byte().
 2. Register 0x4C7 of 8192ee is single byte.

cfg80211_ops structures are only passed as an argument to the function

c93ac39da0 rtlwifi: Remove some redundant code
The symbol DBG_EMERG is no longer used and is removed.

In a number of places, the code has redundant messages. For example, if
the failure for the firmware to run is logged, it is not necessary to
log that the firmware has been started. In addition, extraneous braces are
removed.
