88f07e70d1 wlcore/wl18xx: Add functionality to accept TX rate per link
FW will provide a TX rate per link for each FW status,
and wlcore will be able to store the information for

This is used mainly in mesh.

f4dc77713f netfilter: x_tables: speed up jump target validation
The dummy ruleset I used to test the original validation change was broken,
most rules were unreachable and were not tested by mark_source_chains().

In some cases rulesets that used to load in a few seconds now require
several minutes.

sample ruleset that shows the behaviour:

echo "*filter"
for i in $(seq 0 100000);do
        printf ":chain_%06x - [0:0]\n" $i
done
for i in $(seq 0 100000);do
   printf -- "-A INPUT -j chain_%06x\n" $i
   printf -- "-A INPUT -j chain_%06x\n" $i
   printf -- "-A INPUT -j chain_%06x\n" $i
done
echo COMMIT

[ pipe result into iptables-restore ]

This ruleset will be about 74mbyte in size, with ~500k searches
though all 500k[1] rule entries. iptables-restore will take forever
(gave up after 10 minutes)

Instead of always searching the entire blob for a match, fill an
array with the start offsets of every single ipt_entry struct,
then do a binary search to check if the jump target is present or not.

After this change ruleset restore times get again close to what one
gets when reverting 3647234101 (~3 seconds on my workstation).

[1] every user-defined rule gets an implicit RETURN, so we get
300k jumps + 100k userchains + 100k returns -> 500k rule entries

c0174ee280 wlcore/wl18xx: mesh: added initial mesh support for wl8
1. Added support for interface and role of mesh type.
2. Enabled enable/start of mesh-point role,
   and opening and closing a connection with a mesh peer.
3. Added multirole combination of mesh and ap
   under the same limits of dual ap mode.
4. Add support for 'sta_rc_update' opcode for mesh IF.
   The 'sta_rc_update' opcode is being used in mesh_plink.c.
Add support in wlcore to handle this opcode correctly for mesh
(as opposed to current implementation that handles STA only).
5. Bumped the firmware version to support new Mesh functionality

8cfb86003d mwifiex: Reduce endian conversion for REG Host Commands
For multiple REG Host Commands (e.g HostCmd_CMD_802_11_EEPROM_ACCESS,
HostCmd_CMD_MAC_REG_ACCESS etc.) "cpu_to_leX"-converted values are
saved to driver. So, "leX_to_cpu" conversion is required too many
times afterwards in driver.

This patch reduces the endian: conversion without saving "cpu_to_leX"
converted values in driver. This will convert endianness in prepare
command and command response path.

24da3cc0e2 eeprom: at24: tweak the loop_until_timeout() macro
loop_until_timeout() replaced a do {} while loop in the at24 driver
with a for loop which, under certain circumstances (such as heavy load
or low value of the write_timeout argument), can lead to the code in
the loop never being executed.

Make sure that at least one iteration of the code enclosed within
loop_until_timeout() is always executed.

2287cb47fb [media] doc-rst: move bttv documentation to bttv.rst file
There were several files under Documentation/video4linux/bttv.

Instead of simply copying them to the rst folder, I opted to
merge into a single document and adjust the headers to
adjust the section levels and fix the cards tables.

There are two exceptions on the merge:

- The Tuners were renamed as a separate document, as they
  describe a separate driver;

- I removed the PROBLEMS section. It describes problems with
  the very first generation of 3D boards (Mistique/S3).
  It sounds very unlikely that someone would still need to
  install a bttv board on such hardware. Also, it is not
  very well written, IMHO.

b3802db5eb mmc: pxamci: fix potential oops
As reported by Dan in his report in [1], there is a potential NULL
pointer derefence if these conditions are met :
 - there is no platform_data provided, ie. host->pdata = NULL

Fix this by only using the platform data ro_invert when a gpio for
read-only is provided by the platform data.

This doesn't appear yet as every pxa board provides a platform_data, and
calls pxa_set_mci_info() with a non NULL pointer.

[1] [bug report] mmc: pxamci: fix card detect with slot-gpio API.
The commit fd546ee6a7 ("mmc: pxamci: fix card detect with slot-gpio
API") from Sep 26, 2015, leads to the following static checker warning:

	drivers/mmc/host/pxamci.c:809 pxamci_probe()
	warn: variable dereferenced before check 'host->pdata' (see line 798)
