On BCM58xx devices (Northstar Plus), there is an accelerator attached to
port 8 which would only work if we use prepended Broadcom tags. Resolve
that difference in our get_tag_protocol() function by setting the
appropriate tagging protocol in that case. We need to change
b53_brcm_hdr_setup() a little bit now since we can deal with two types
of Broadcom tags.

A number of drivers want to check whether the configured CPU port is a
possible configuration for enabling tagging, pass down the CPU port
number so they verify that.

Since Mellanox focus is on newer adapters, we would like to have the
ability to disable the support for old gen2 adapters.
This can be done by turning off the MLX4_CORE_GEN2 Kconfig flag.
We keep it turned on by default.

The variable giga_ctrl is being assigned to zero however this is
never read and hence the assignment is redundant, so remove it.

Marc Kleine-Budde says:
====================
pull-request: can 2017-11-10
this is a pull request for net/master.
The first patch by Richard Schütz for the c_can driver removes the false
indication to support triple sampling for d_can. Gerhard Bertelsmann's
patch for the sun4i driver improves the RX overrun handling. The patch
by Stephane Grosjean for the peak_canfd driver adds the PCI ids for
various new PCIe/M2 interfaces. Marek Vasut's patch for the ifi driver
fix transmitter delay calculation.

This adds support for the following PEAK-System CAN FD interfaces:
PCAN-cPCIe FD CAN FD Interface for cPCI Serial (2 or 4 channels)
PCAN-PCIe/104-Express CAN FD Interface for PCIe/104-Express (1, 2 or 4 ch.)
PCAN-miniPCIe FD CAN FD Interface for PCIe Mini (1, 2 or 4 channels)
PCAN-PCIe FD OEM CAN FD Interface for PCIe OEM version (1, 2 or 4 ch.)
PCAN-M.2 CAN FD Interface for M.2 (1 or 2 channels)
Like the PCAN-PCIe FD interface, all of these boards run the same IP Core
that is able to handle CAN FD (see also http://www.peak-system.com).

Currently, when dma mapping fails, put_page is called,
but the page is not set to null. Later, in the page_reuse treatment in
mlx5e_free_rx_descs(), mlx5e_page_release() is called for the second time,
improperly doing dma_unmap (for a non-mapped address) and an extra put_page.
Prevent this by nullifying the page pointer when dma_map fails.

napi->poll can be called with budget 0, e.g. in netpoll scenarios
where the caller only wants to poll TX rings
(poll_one_napi@net/core/netpoll.c).
The below commit changed RX polling from "while" loop to "do {} while",
which caused to ignore the initial budget and handle at least one RX
packet.
This fixes the following warning:
[ 2852.049194] mlx5e_napi_poll+0x0/0x260 [mlx5_core] exceeded budget in poll

After the panic teardown firmware command, health_care detects the error
in PCI bus and calls the mlx5_pci_err_detected. This health_care flow is
no longer needed because the panic teardown firmware command will bring
down the PCI bus communication with the HCA.
The solution is to cancel the health care timer and its pending
workqueue request before sending panic teardown firmware command.

Pull input layer updates from Dmitry Torokhov:
- a new ACPI ID for Elan touchpad found in yet another Ideapad model
- Synaptics RMI4 will allow binding to controllers reporting SMB
version 3 (note that we are not adding any new ACPI IDs to the
Synaptics PS/2 drover so unless user explicitly enables intertouch
support there is no user-visible change)
- a fixup to TSC 2004/5 touchscreen driver to mark input devices as
"direct" to help userspace identify the type of device they are
dealing with

If INPUT_PROP_DIRECT is set, userspace doesn't have to fall back to old
ways of identifying touchscreen devices.
In order to identify a touchscreen device, Android for example, seems to
already depend on INPUT_PROP_DIRECT to be present in drivers. udev still
checks for either BTN_TOUCH or INPUT_PROP_DIRECT. Checking for BTN_TOUCH
however can quite easily lead to false positives; it's a code that not only
touchscreen device drivers use.
According to the documentation, touchscreen drivers should have this
property set and in order to make life easy for userspace, let's set it.

This is an extension of Commit 7c20d213dd3c ("drm/vmwgfx: Work
around mode set failure in 2D VMs")
With Wayland desktop and atomic mode set, during the mode setting
process there is a moment when two framebuffer sized surfaces
are being pinned. This was not an issue with Xorg.
Since this only happens during a mode change, there should be no
performance impact by increasing allowable mem_size.

The firmware for brcmfmac devices includes information regarding
regulatory constraints. For certain devices this information is kept
separately in a binary form that needs to be downloaded to the device.
This patch adds support to download this so-called CLM blob file. It
uses the same naming scheme as the other firmware files with extension
of .clm_blob.
The CLM blob file is optional. If the file does not exist, the download
process will be bypassed. It will not affect the driver loading.

rt2x00 uses the deprecated do_gettimeofday() function to get a timestamp
for its debugfs "dump" file interface.
The timestamp is using an unsigned 32-bit value, so we could make it
work until 2106 by using ktime_get_real_ts64(), but it seems better to
use monotonic times, as we normally want for timestamps.
Since this is an interface change, I'm incrementing the
DUMP_HEADER_VERSION number, so user space can figure out whether the
timestamps are monotonic or not. Most likely the tools won't care either
way.
Generally speaking, ABI version numbers and in particular changing them
is a bad idea. However since this is in debugfs, we don't put any
API stability rules on the interface according to
Documentation/filesystems/debugfs.txt, and we can take the easy way
out here; anyone using the frame dump feature can probably work out
the differences here.

ENOENT usb error mean "specified interface or endpoint does not exist or
is not enabled". Mark device not present when we encounter this error
similar like we do with ENODEV error.
Otherwise we can have infinite loop in rt2x00usb_work_rxdone(), because
we remove and put again RX entries to the queue infinitely.
We can have similar situation when submit urb will fail all the time
with other error, so we need consider to limit number of entries
processed by rxdone work. But for now, since the patch fixes
reproducible soft lockup issue on single processor systems
and taken ENOENT error meaning, let apply this fix.
Patch adds additional ENOENT check not only in rx kick routine, but
also on other places where we check for ENODEV error.

- BSSID hint
- previous BSSID for reassoc request

Current logic artificially divides "start AP" procedure into three
stages:
- generic interface configuration (security, channel etc)
- IE's processing
- enable AP mode on interface
This separation would not allow to do a proper device configuration as
first stage needs to use information from IEs that are processed on
a second stage. Which means first and second stages have to be meged.
In that case there is no point anymore to keep third stage either, so
merge all three into a single command.
This new command carries all the same info as contained in
"struct cfg80211_ap_settings".

HT/VHT capabilities must be reported per each band supported by a radio,
not for all bands on a radio. Furthermore, driver better not assume
any capabilities and just use whetever is reported by device itself.
To support this, convert "get channels" command into "get band info"
command. Difference is that it may also carry HT/VHT capabilities along
with channels information.
While at it, also add "num_bitrates" field to "get band info" command,
for future use.
