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.

Since commit 1bdf02326b71e ("clk: at91: make use of syscon/regmap
internally"), clk_programmable_set_parent() is always selecting the
first parent (AKA slow_clk), no matter what's passed in the 'index'
parameter.
Fix that by initializing the pckr variable to the index value.

Jirka reported that python code returns all arrays as strings. This
makes impossible to get all items for byte array tracepoint field
containing 0x00 value item.
Fixing this by scanning full length of the array and returning it as
PyByteArray object in case non printable byte is found.

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.

The i915 driver checks for color management properties changes as part
of a plane update. Therefore a color management update must imply a

eDP should be treated as connected even if doesn't have an EDID. In that
case we'll use the timings from the VBT. That used to be the case until
commit f21a21983ef1 ("drm/i915: Splitting intel_dp_detect")
broke things by considering even eDP disconnected if we fail to get
an EDID for it.

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.

Arbitrary X.509 certificates without authority key identifiers (AKIs)
can be added to "trusted" keyrings, including IMA or EVM certs loaded
from the filesystem. Signature verification is currently bypassed for
certs without AKIs.
Trusted keys were recently refactored, and this bug is not present in
4.6.
restrict_link_by_signature should return -ENOKEY (no matching parent
certificate found) if the certificate being evaluated has no AKIs,
instead of bypassing signature checks and returning 0 (new certificate

The label lio_xmit_failed is used 3 times through liquidio_xmit() but it
always makes a call to dma_unmap_single() using potentially
uninitialized variables from "ndata" variable. Out of the 3 gotos, 2 run
after ndata has been initialized, and had a prior dma_map_single() call.
Fix this by adding a new error label: lio_xmit_dma_failed which does
this dma_unmap_single() and then processed with the lio_xmit_failed
fallthrough.

We should be using a logical check here instead of a bitwise operation
to check if the device is closed already in et131x_tx_timeout().

macsec can't cope with mtu frames which need vlan tag insertion, and
vlan device set the default mtu equal to the underlying dev's one.
By default vlan over macsec devices use invalid mtu, dropping
all the large packets.
This patch adds a netif helper to check if an upper vlan device
needs mtu reduction. The helper is used during vlan devices
initialization to set a valid default and during mtu updating to
forbid invalid, too bit, mtu values.
The helper currently only check if the lower dev is a macsec device,
if we get more users, we need to update only the helper (possibly
reserving an additional IFF bit).

phy-sun4i-usb now has proper dr_mode handling, it always registers an
extcon, and sends a notify with the mode (even when in peripheral- /
host-only mode) at least once.
So we can simply the sunxi musb glue by always registering its extcon
notifier and relying on sunxi_musb_work() to enable vbus when in
host-only mode.
This also enables host- and peripheral-only mode with vbus monitoring.

The sunxi_musb_dma_controller_create and _destroy are not exported
or used outside the driver, so fix sparse warnings by making these
two static:
drivers/usb/musb/sunxi.c:357:23: warning: symbol 'sunxi_musb_dma_controller_create' was not declared. Should it be static?
drivers/usb/musb/sunxi.c:363:6: warning: symbol 'sunxi_musb_dma_controller_destroy' was not declared. Should it be static?
