Destination mac is a mandatory specification for ip/udp steering rules.
When attaching multicast steering rules via ethtool the unicast mac of the
interface was added to the rule specification instead of the multicast mac.
The following commit sets the corresponding multicast mac for the rule multicast ip.

If occurs a LE or SCO hci_conn timeout and the connection is already
established (BT_CONNECTED state), the connection is not terminated as
expected. This bug can be reproduced using l2test or scotest tool.
Once the connection is established, kill l2test/scotest and the
connection won't be terminated.
This patch fixes hci_conn_disconnect helper so it is able to
terminate LE and SCO connections, as well as ACL.

The conn->smp_chan pointer can be NULL if SMP PDUs arrive at unexpected
moments. To avoid NULL pointer dereferences the code should be checking
for this and disconnect if an unexpected SMP PDU arrives. This patch
fixes the issue by adding a check for conn->smp_chan for all other PDUs
except pairing request and security request (which are are the first
PDUs to come to initialize the SMP context).

LCDC clock node is a one that does not have set rate capability. It
just passes on the rate that is sent downstream by it's parent. While
lcdc clock parent and it's grand parent - dpll_disp_m2_ck and
dpll_disp_ck has the capability to configure rate.
And the default rates provided by LCDC clock's ancestors are not
sufficient to obtain pixel clock for current LCDC use cases, hence
currently display would not work on AM335x SoC's (with driver
modifications in platfrom independent way).
Hence inform clock framework to propogate set rate for LCDC clock as
well as it's parent - dpll_disp_m2_ck. With this change, set rate on
LCDC clock would get propogated till dpll_disp_ck via dpll_disp_m2_ck,
hence allowing the driver (same driver is used in DaVinci too) to set
rates using LCDC clock without worrying about platform dependent clock
details.

i2c_hid_output_raw_report is used by hidraw to forward set_report requests.
The current implementation of i2c_hid_set_report needs to take the
report_id as an argument. The report_id is stored in the first byte
of the buffer in argument of i2c_hid_output_raw_report.
Not removing the report_id from the given buffer adds this byte 2 times
in the command, leading to a non working command.

This patchset addes two new sets of files to sysfs for POWER architecture.
- perf event config format in /sys/devices/cpu/format/event
- generic and POWER-specific perf events in /sys/devices/cpu/events/
The format of the first file is already documented in:
sysfs-bus-event_source-devices-format
Document the format of the second set of files '/sys/devices/cpu/events/*'
which would also become part of the ABI.
Changelog[v4]:
[Jiri Olsa]: Mention that multiple event= like terms can be specified
in the 'events' file.
[Jiri Olsa]: Remove the documentation for the 'config format' file
as it is already documented in 'Documentation/ABI/testing/'.
[Jiri Olsa]: Move ABI documentation from 'stable/' to 'testing/'
Changelog[v3]:
[Greg KH] Include ABI documentation.

Just return to the perf main() routine so that an unified exit path can
be followed and resources released, helping in finding memory leaks.

If we're booted in HYP mode, it is possible that we'll run some
kind of virtualized environment. In this case, it is a better to
switch to the physical timers, and leave the virtual timers to
guests.

Currently the documentation for the arch_timer devicetree binding only
lists "arm,armv7-timer".
Add "arm,armv8-timer" to the list of compatible strings.

The arch_timer driver supports a superset of the functionality of the
arm_generic driver, and is not tied to a particular arch.
This patch moves arm64 to use the arch_timer driver, gaining additional
functionality in doing so, and removes the (now unused) arm_generic
driver. Timer-related hooks specific to arm64 are moved into
arch/arm64/kernel/time.c.

Currently arch_counter_get_cnt{p,v}ct can be speculated, allowing for
stale time values to be read. This could be problematic for the delay
loop and other sensitive functions, as the time delta could jump around
unexpectedly.
This patch adds isbs to arch_counter_get_cnt{p,v}ct, preventing this
possibility.

The core functionality of the arch_timer driver is not directly tied to
anything under arch/arm, and can be split out.
This patch factors out the core of the arch_timer driver, so it can be
shared with other architectures. A couple of functions are added so
that architecture-specific code can interact with the driver without
needing to touch its internals.
The ARM_ARCH_TIMER config variable is moved out to
drivers/clocksource/Kconfig, existing uses in arch/arm are replaced with
HAVE_ARM_ARCH_TIMER, which selects it.

The last field of the driver_data->leds[] array is used to store the
special toggle for setting all leds simultaneously, so we need to allocate
appropriate number of led_classdev pointers.
