Tariq Toukan says:
====================
Safe flow for mlx4_en configuration change
This patchset improves the mlx4_en driver resiliency, especially on
systems with low memory. Upon a configuration change that requires
the allocation of new resources, we first try to allocate, prior to
destroying the current ones. Once it is successfully done,
we release the old resources and attach the new ones. Otherwise, we
stay with a functioning interface having the same old configuration.
This improvement became of greater significance after removing the use
of vmap.

This patch fixes the lost of Ethernet port on low memory system,
when driver frees its resources and fails to allocate new resources.
Issue could happen while changing number of channels, rings size or
changing the timestamp configuration.
This fix is necessary because of removing vmap use in the code.
When vmap was in use driver could allocate non-contiguous memory
and make it contiguous with vmap. Now it could fail to allocate
a large chunk of contiguous memory and lose the port.
Current code tries to allocate new resources and then upon success
frees the old resources.

Unfortunately warnings generated after parsing in sphinx can end up
with entirely bogus files and line numbers as sources. Strangely for
outright errors this is not a problem. Trying to convert warnings to
errors also doesn't fix it.
The only way to get useful output out of sphinx to be able to root
cause the error seems to be enabling keep_warnings, which inserts
a System Message into the actual output. Not pretty at all, but I
don't really want to fix up core rst/sphinx code, and this gets the job
done meanwhile.

Commit 4995734e973a "acpi, nfit: fix acpi_check_dsm() vs zero functions
implemented" attempted to fix a QEMU regression by supporting its usage
of a zero-mask as a valid response to a DSM-family probe request.
However, this behavior breaks HP platforms that return a zero-mask by
default causing the probe to misidentify the DSM-family.
Instead, the QEMU regression can be fixed by simply not requiring the DSM
family to be identified.
This effectively reverts commit 4995734e973a, and removes the DSM
requirement from the init path.

tick_nohz_start_idle is called before checking whether the idle tick can be
stopped. If the tick cannot be stopped, calling tick_nohz_start_idle() is
pointless and just wasting CPU cycles.
Only invoke tick_nohz_start_idle() when can_stop_idle_tick() returns true. A
short one minute observation of the effect on ARM64 shows a reduction of calls
by 1.5% thus optimizing the idle entry sequence.

git://anongit.freedesktop.org/drm-intel into drm-fixes
As promised here's the pile of kbl cherry-picks assembled by Mika&Rodrigo.
It's a bit much, but all well-contained to kbl code and been tested for a
while in drm-intel-next. Still separate in case too much, but in that case
I think we'd need to disable kbl by default again (which would be annoying
too) in 4.7.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
- Properly report when a function wildcard produces no matches in 'perf probe'
(Masami Hiramatsu)
- Balance opening and reading events in 'perf stat', which could cause
it to get stuck trying to close invalid file descriptors (Mark Rutland)
Infrastructure changes:
- Copy more headers from the kernel, this time for headers that
were just including the contents of its kernel counterparts, should
help resolving the problems with linux-next, where some uapi related
patches seem to be breaking tools/object/ build. (Arnaldo Carvalho de Melo)
Some more combing will be done, but at least it is possible to build
perf out of tree, via a detached tarball (make help | grep perf),
without including kernel files in its MANIFEST (Arnaldo Carvalho de Melo)
- Fix smatch found errors that were not causing problems, but are
mistakes nonetheless (Dan Carpenter)
- Fix string vs. byte array resolving in the python script code (Jiri Olsa)

In kernel HTB keeps tokens in signed 64-bit in nanoseconds. In netlink
protocol these values are converted into pshed ticks (64ns for now) and
truncated to 32-bit. In struct tc_htb_xstats fields "tokens" and "ctokens"
are declared as unsigned 32-bit but they could be negative thus tool 'tc'
prints them as signed. Big values loose higher bits and/or become negative.
This patch clamps tokens in xstat into range from INT_MIN to INT_MAX.
In this way it's easier to understand what's going on here.

Warn unmatched function filter correctly instead of warning
"symbol-loading error", since that can be a filter issue.
From the technical point of view, this adds a filter chech in map__load
and if there is a filter, it returns -2 (filter-out), instead of -1
(error), and perf-probe checks it and change message.
E.g. without this fix:
# perf probe -F rt_sp*
no symbols found in [kernel.kallsyms], maybe install a debug package?
Failed to load symbols in kernel
With this fix:
# perf probe -F rt_sp*
no symbols passed the given filter.
Failed to find symbols matched to "rt_sp*"
Error: Failed to show functions.

In some cases it's necessry to figure out the map-local index of a given
Linux logical CPU ID. Add a new helper, cpu_map__idx, to acquire this.
As the logic is largely the same as the existing cpu_map__has, this is
rewritten in terms of the new helper.
At the same time, add the inverse operation, cpu_map__cpu, which yields
the logical CPU id for a map-local index. While this can be performed
manually, wrapping this in a helper can make code more legible.

In create_perf_stat_counter, when a target CPU has not been provided, we
call __perf_evsel__open with empty_cpu_map, and open a single FD per
thread. However, in read_counter we assume that we opened events for the
product of threads and CPUs described in the evsel's cpu_map.
Thus, if an evsel has a cpu_map with more than one entry, we will
attempt to access FDs that we didn't open. This could result in a number
of problems (e.g. blocking while reading from STDIN if the fd memory
happened to be initialised to zero).
This is problematic for systems were a logical CPU PMU covers some
arbitrary subset of CPUs. The cpu_map of any evsel for that PMU will be
initialised based on the cpumask exposed through sysfs, even if the user
requests per-thread events.

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 fd546ee6a7dc ("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)
Fixes: fd546ee6a7dc ("mmc: pxamci: fix card detect with slot-gpio API")

The code that fills packed command header assumes that CPU runs in
little-endian mode. Hence the header is malformed in big-endian mode
and causes MMC data transfer errors:
[ 563.200828] mmcblk0: error -110 transferring data, sector 2048, nr 8, cmd response 0x900, card status 0xc40
[ 563.219647] mmcblk0: packed cmd failed, nr 2, sectors 16, failure index: -1
Convert header data to LE.
