In the error flow of adding flow rule to auto-grouped flow
table, we call to tree_remove_node.
tree_remove_node locks the node's parent, however the node's parent
is already locked by mlx5_add_flow_rule and this causes a deadlock.
After this patch, if we failed to add the flow rule, we unlock the
flow table before calling to tree_remove_node.

Both socfpga_dwmac_parse_data() in dwmac-socfpga.c and stmmac_dvr_probe()
in stmmac_main.c functions call devm_reset_control_get() to register an
reset controller for the stmmac. This results in an attempt to register
two reset controllers for the same non-shared reset line.
The first attempt to register the reset controller works fine. The second
attempt fails with warning from the reset controller core, see below.
The warning is produced because the reset line is non-shared and thus
it is allowed to have only up-to one reset controller associated with
that reset line, not two or more.
The solution has multiple parts. First, the original socfpga_dwmac_init()
is tweaked to use reset controller pointer from the stmmac_priv (private
data of the stmmac core) instead of the local instance, which was used
before. The local re-registration of the reset controller is removed.
Next, the socfpga_dwmac_init() is moved after stmmac_dvr_probe() in the
probe function. This order is legal according to Altera and it makes the
code much easier, since there is no need to temporarily register and
unregister the reset controller ; the reset controller is already registered
by the stmmac_dvr_probe().
Finally, plat_dat->exit and socfpga_dwmac_exit() is no longer necessary,
since the functionality is already performed by the stmmac core.

The variable_matches() function can currently read "var_name[len]", for
example when:
- var_name[0] == 'a',
- len == 1
- match_name points to the NUL-terminated string "ab".
This function is supposed to accept "var_name" inputs that are not
NUL-terminated (hence the "len" parameter"). Document the function, and
access "var_name[*match]" only if "*match" is smaller than "len".

Merge "omap fixes against v4.6-rc2" from Tony Lindgren
Fixes for omaps against v4.6-rc2, mostly to fix suspend for beagle-x15
that broke when we added runtime based SoC revision detection earlier.
It seems suspend worked earlier as things were only partially initialized,
while now we initialize things properly for dra7.
Note that the "ARM: OMAP: Catch callers of revision information prior
to it being populated" had to be reverted as it caused bogus warnings
for other SoCs because omap initcalls bail out based on revision being
set to 0 for other SoCs. These initcalls will mostly just disappear
when we drop support for omap3 legacy booting.
Also included is a fix for dra7 sys_32k_ck clock source that is not

The exynos5 I2C controller driver always prepares and enables a clock
before using it and then disables unprepares it when the clock is not
used anymore.
But this can cause a possible ABBA deadlock in some scenarios since a
driver that uses regmap to access its I2C registers, will first grab
the regmap lock and then the I2C xfer function will grab the prepare
lock when preparing the I2C clock. But since the clock driver also
uses regmap for I2C accesses, preparing a clock will first grab the
prepare lock and then the regmap lock when using the regmap API.
An example of this happens on the Exynos5422 Odroid XU4 board where a
s2mps11 PMIC is used and both the s2mps11 regulators and clk drivers
share the same I2C regmap.
The possible deadlock is reported by the kernel lockdep:
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(sec_core:428:(regmap)->lock);
lock(prepare_lock);
lock(sec_core:428:(regmap)->lock);
lock(prepare_lock);
*** DEADLOCK ***
Fix it by leaving the code prepared on probe and use {en,dis}able in
the I2C transfer function.
This patch is similar to commit 34e81ad5f0b6 ("i2c: s3c2410: fix ABBA
deadlock by keeping clock prepared") that fixes the same bug in other
driver for an I2C controller found in Samsung SoCs.

Haswell and Broadwell can be configured to hash the channel
interleave function using bits [27:12] of the physical address.
On those processor models we must check to see if hashing is

act accordingly.

Allowing userptr bo which are basicly a list of page from some vma
(so either anonymous page or file backed page) would lead to serious
corruption of kernel structures and counters (because we overwrite
the page->mapping field when mapping buffer).
This will already block if the buffer was populated before anyone does
try to mmap it because then TTM_PAGE_FLAG_SG would be set in in the
ttm_tt flags. But that flag is check before ttm_tt_populate in the ttm
vm fault handler.
So to be safe just add a check to verify_access() callback.

With the joys of things running concurrently, there's always a chance
that the port we get passed in drm_dp_payload_send_msg() isn't actually
valid anymore. Because of this, we need to make sure we validate the
reference to the port before we use it otherwise we risk running into
various race conditions. For instance, on the Dell MST monitor I have
here for testing, hotplugging it enough times causes us to kernel panic:
[drm:intel_mst_enable_dp] 1
[drm:drm_dp_update_payload_part2] payload 0 1
[drm:intel_get_hpd_pins] hotplug event received, stat 0x00200000, dig 0x10101011, pins 0x00000020
[drm:intel_hpd_irq_handler] digital hpd port B - short
[drm:intel_dp_hpd_pulse] got hpd irq on port B - short
[drm:intel_dp_check_mst_status] got esi 00 10 00
[drm:drm_dp_update_payload_part2] payload 1 1

Which occurs because of the hotplug event shown in the log, which ends
up causing DRM's dp helpers to drop the port we're updating the payload
on and panic.

Pull power management fixes from Rafael Wysocki:
"Two fixes for issues introduced recently, one for an intel_pstate
driver problem uncovered by the recent switch over from using timers
and the other one for a potential cpufreq core problem related to
system suspend/resume.
Specifics:
- Fix an intel_pstate driver problem causing CPUs to get stuck in the
highest P-state when completely idle uncovered by the recent switch
over from using timers (Rafael Wysocki).
- Avoid attempts to get the current CPU frequency when all devices
(like I2C controllers that may be nedded for that purpose) have
been suspended during system suspend/resume (Rafael Wysocki)"
* tag 'pm+acpi-4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
cpufreq: Abort cpufreq_update_current_freq() for cpufreq_suspended set

With commit 8bc2a40730ec ("rtc: ds1307: add support for the
DT property 'wakeup-source'") we lost the ability for rtc irq
functionality for devices that are actually hooked on a real IRQ
line and have capability to wakeup as well. This is not an expected
behavior. So, instead of just not requesting IRQ, skip the IRQ
requirement only if interrupts are not defined for the device.

while retrieving temperature from ds3231, the result may be overflow
since s16 is too small for a multiplication with 250.
ie. if temp_buf[0] == 0x2d, the result (s16 temp) will be negative.
