Use relative path to trigger file instead of absolute debugfs path,
because if the user uses tracefs instead of debugfs, it can be
mounted at /sys/kernel/tracing.
Anyway, since the ftracetest is designed to be run at the tracing
directory, user doesn't need to use absolute path.

Since dynamic function tracer can be disabled, set_ftrace_filter
can be disappeared. Test cases which depends on it, must check
whether the set_ftrace_filter exists or not before testing
and if not, return as unsupported.
Also, if the function tracer itself is disabled, we can not
set "function" to current_tracer. Test cases must check it
before testing, and return as unsupported.

If we run ftracetest on the kernel with CONFIG_DYNAMIC_FTRACE=n,
there is no set_ftrace_filter and all test cases are failed, because
reset_ftrace_filter() returns an error.
Let's check whether set_ftrace_filter exists in reset_ftrace_filter()
and clean up only set_ftrace_notrace in initialize_ftrace().

1) syzbot reported an uninit-value in bond_neigh_setup() [1]
bond_neigh_setup() uses a temporary on-stack 'struct neigh_parms parms',
but only clears parms.neigh_setup field.
A stacked bonding device would then enter bond_neigh_setup()
and read garbage from parms->dev.
If we get really unlucky and garbage is matching @dev, then we
could recurse and eventually crash.
Let's make sure the whole structure is cleared to avoid surprises.
2) bond_neigh_setup() can be called while another cpu manipulates
the master device, removing or adding a slave.
We need at least rcu protection to prevent use-after-free.
Note: Prior code does not support a stack of bonding devices,
this patch does not attempt to fix this, and leave a comment instead.

Marc Kleine-Budde says:
====================
pull-request: can 2019-12-08
this is a pull request of 13 patches for net/master.
The first two patches are by Dan Murphy. He adds himself as a maintainer to the
m-can MMIO and tcan SPI driver.
The next two patches the j1939 stack. The first one is by Oleksij Rempel and
fixes a locking problem found by the syzbot, the second one is by me an fixes a
mistake in the documentation.
Srinivas Neeli fixes missing RX CAN packets on CANFD2.0 in the xilinx driver.
Sean Nyekjaer fixes a possible deadlock in the the flexcan driver after
suspend/resume. Joakim Zhang contributes two patches for the flexcan driver
that fix problems with the low power enter/exit.
The next 4 patches all target the tcan part of the m_can driver. Sean Nyekjaer
adds the required delay after reset and fixes the device tree binding example.
Dan Murphy's patches make the wake-gpio optional.
In the last patch Xiaolong Huang fixes several kernel memory info leaks to the
USB device in the kvaser_usb_leaf driver.

Make the AFS dynamic root superblock R/W so that SELinux can set the
security label on it. Without this, upgrades to, say, the Fedora
filesystem-afs RPM fail if afs is mounted on it because the SELinux label
can't be (re-)applied.
It might be better to make it possible to bypass the R/O check for LSM
label application through setxattr.

afs_find_server tries to find a server that has an address that
matches the transport address of an rxrpc peer. The code assumes
that the transport address is always ipv6, with ipv4 represented
as ipv4 mapped addresses, but that's not the case. If the transport
family is AF_INET, srx->transport.sin6.sin6_addr.s6_addr32[] will
be beyond the actual ipv4 address and will always be 0, and all
ipv4 addresses will be seen as matching.
As a result, the first ipv4 address seen on any server will be
considered a match, and the server returned may be the wrong one.
One of the consequences is that callbacks received over ipv4 will
only be correctly applied for the server that happens to have the
first ipv4 address on the fs_addresses4 list. Callbacks over ipv4
from all other servers are dropped, causing the client to serve stale
data.
This is fixed by looking at the transport family, and comparing ipv4
addresses based on a sockaddr_in structure rather than a sockaddr_in6.

As virtual_context_destroy() may be called from a request signal, it may
be called from inside an irq-off section, and so we need to do a full

sets
The existing rbtree implementation might store consecutive elements
where the closing element and the opening element might overlap, eg.
[ a, a+1) [ a+1, a+2)
This patch removes the optimization for non-anonymous sets in the exact
matching case, where it is assumed to stop searching in case that the
closing element is found. Instead, invalidate candidate interval and
keep looking further in the tree.
The lookup/get operation might return false, while there is an element
in the rbtree. Moreover, the get operation returns true as if a+2 would
be in the tree. This happens with named sets after several set updates.
The existing lookup optimization (that only works for the anonymous
sets) might not reach the opening [ a+1,... element if the closing
...,a+1) is found in first place when walking over the rbtree. Hence,
walking the full tree in that case is needed.
This patch fixes the lookup and get operations.

Since commit ca74b316df96 ("arm: Use common cpu_topology structure and
functions.") the core cpumask has to be modified during cpu hotplug
operations. So using them to set up cpufreq policy cpumask may be
incorrect as it may contain only cpus that are online at that instance.
Instead, we can use the cpumask setup by OPP library that contains all
the cpus sharing OPP table using dev_pm_opp_get_sharing_cpus.

Currently we add individual copy of same OPP table for each CPU within
the cluster. This is redundant and doesn't reflect the reality.
We can't use core cpumask to set policy->cpus in ve_spc_cpufreq_init()
anymore as it gets called via cpuhp_cpufreq_online()->cpufreq_online()
->cpufreq_driver->init() and the cpumask gets updated upon CPU hotplug
operations. It also may cause issues when the vexpress_spc_cpufreq
driver is built as a module.
Since ve_spc_clk_init is built-in device initcall, we should be able to
use the same topology_core_cpumask to set the opp sharing cpumask via
dev_pm_opp_set_sharing_cpus and use the same later in the driver via
dev_pm_opp_get_sharing_cpus.

Commit 39ce8150a079 ("pinctrl: baytrail: Serialize all register access")
added a spinlock around all register accesses because:
"There is a hardware issue in Intel Baytrail where concurrent GPIO register
access might result reads of 0xffffffff and writes might get dropped
completely."
Testing has shown that this does not catch all cases, there are still
2 problems remaining
1) The original fix uses a spinlock per byt_gpio device / struct,
additional testing has shown that this is not sufficient concurent
accesses to 2 different GPIO banks also suffer from the same problem.
This commit fixes this by moving to a single global lock.
2) The original fix did not add a lock around the register accesses in
the suspend/resume handling.
Since pinctrl-baytrail.c is using normal suspend/resume handlers,
interrupts are still enabled during suspend/resume handling. Nothing
should be using the GPIOs when they are being taken down, _but_ the
GPIOs themselves may still cause interrupts, which are likely to
use (read) the triggering GPIO. So we need to protect against
concurrent GPIO register accesses in the suspend/resume handlers too.
This commit fixes this by adding the missing spin_lock / unlock calls.
The 2 fixes together fix the Acer Switch 10 SW5-012 getting completely
confused after a suspend resume. The DSDT for this device has a bug
in its _LID method which reprograms the home and power button trigger-
flags requesting both high and low _level_ interrupts so the IRQs for
these 2 GPIOs continuously fire. This combined with the saving of
registers during suspend, triggers concurrent GPIO register accesses
resulting in saving 0xffffffff as pconf0 value during suspend and then
when restoring this on resume the pinmux settings get all messed up,
resulting in various I2C busses being stuck, the wifi no longer working
and often the tablet simply not coming out of suspend at all.

With commit 222ec1618c3ace ("drm: Add aspect ratio parsing in DRM
layer") the drm core started honoring the picture_aspect_ratio field
when comparing two drm_display_modes. Prior to that it was ignored.
When the CVBS encoder driver was initially submitted there was no aspect
ratio check.
Switch from drm_mode_equal() to drm_mode_match() without
DRM_MODE_MATCH_ASPECT_RATIO to fix "kmscube" and X.org output using the
CVBS connector. When (for example) kmscube sets the output mode when
using the CVBS connector it passes HDMI_PICTURE_ASPECT_NONE, making the
drm_mode_equal() fail as it include the aspect ratio.
Prior to this patch kmscube reported:
failed to set mode: Invalid argument
The CVBS mode checking in the sun4i (drivers/gpu/drm/sun4i/sun4i_tv.c
sun4i_tv_mode_to_drm_mode) and ZTE (drivers/gpu/drm/zte/zx_tvenc.c
tvenc_mode_{pal,ntsc}) drivers don't set the "picture_aspect_ratio" at
all. The Meson VPU driver does not rely on the aspect ratio for the CVBS
output so we can safely decouple it from the hdmi_picture_aspect
setting.

Switch the handling of min_freq and max_freq from sysfs to use the
dev_pm_qos_request interface.
Since PM QoS handles frequencies as kHz this change reduces the
precision of min_freq and max_freq. This shouldn't introduce problems
because frequencies which are not an integer number of kHz are likely
not an integer number of Hz either.
Try to ensure compatibility by rounding min values down and rounding
max values up.

Right now devfreq_dev_release will print a warning and abort the rest of
the cleanup if the devfreq instance is not part of the global
devfreq_list. But this is a valid scenario, for example it can happen if
the governor can't be found or on any other init error that happens
after device_register.
Initialize devfreq->node to an empty list head in devfreq_add_device so
that list_del becomes a safe noop inside devfreq_dev_release and we can
continue the rest of the cleanup.

Moving handling of min/max freq to a single function and call it from
update_devfreq and for printing min/max freq values in sysfs.
This changes the behavior of out-of-range min_freq/max_freq: clamping
is now done at evaluation time. This means that if an out-of-range
constraint is imposed by sysfs and it later becomes valid then it will
be enforced.

The devfreq_notifier_call functions will update scaling_min_freq and
scaling_max_freq when the OPP table is updated.
If fetching the maximum frequency fails then scaling_max_freq remains
set to zero which is confusing. Set to ULONG_MAX instead so we don't
need special handling for this case in other places.

Notifier callbacks shouldn't return negative errno but one of the
NOTIFY_OK/DONE/BAD values.
The OPP core will ignore return values from notifiers but returning a
value that matches NOTIFY_STOP_MASK will stop the notification chain.
Fix by always returning NOTIFY_OK.

The power button was only producing irqs, but no key events,
Forced power down with long key press works, so probably
only a short spike arrives at the SoC.
Further investigation shows that LDORTC2 is off after boot
of the vendor kernel. LDORTC2 is shared with a GPIO at the pmic
which probably transfers the button press to the SoC.
That regulator off at boot, so "regulator-boot-on" is definitively
wrong. So remove that.
