cmos_read_alarm() may leave certain fields of a struct rtc_time
untouched; therefore, these fields contain garbage if not properly
initialized, leading to inconsistent values when converting into
time64_t.
This patch to set all fields of a struct rtc_time to -1 before calling
cmos_read_alarm().

dev_pm_opp_set_rate() can now be called with freq = 0 in order
to either drop performance or bandwidth votes or to disable
regulators on platforms which support them.
In such cases, a subsequent call to dev_pm_opp_set_rate() with
the same frequency ends up returning early
The OPP core needs to track if the resources of devices are enabled or
configured or not, as it disables the resources when target_freq is set
to 0.
Handle that with a separate variable to make it easy to maintain.
Also note that we will unconditionally call clk_set_rate() in the case

Use kobj_to_dev() instead of container_of()

Hi Linus,
Please pull these two small fixes that have come in during the past
week. The branch merges cleanly with upstream as of a few minutes ago,
so please let me know if anything strange happens.
--D
The following changes since commit 818d5a91559ffe1e1f2095dcbbdb96c13fdb94ec:
fs/xfs:
Recently, we have observed some janky issues caused by unpleasantly long
contention on mmap_lock which is held by smaps_rollup when probing large
processes. To address the problem, we let smaps_rollup detect if anyone
wants to acquire mmap_lock for write attempts. If yes, just release the
lock
Add new API to query if someone wants to acquire mmap_lock
for write attempts.
Using this instead of rwsem_is_contended makes it more tolerant
of future changes to the lock type.

smaps_rollup will try to grab mmap_lock and go through the whole vma
list until it finishes the iterating. When encountering large processes,
the mmap_lock will be held for a longer time, which may block other
write requests like mmap and munmap from progressing smoothly.
There are upcoming

To avoid mixup of packets from differnt ftrace packets simultaneously,
use different channel for packets from different CPU.

Ftrace has ability to export trace packets to other destination.
Currently, only function trace can be exported. This series extends the
support to event trace and trace_maker. STM is one possible destination to
export ftrace. Use separate channel for each CPU to avoid mixing up packets
from
More traces like event trace or trace marker will be supported.
Add flag for difference traces, so that they can be controlled
separately. Move current function trace to it's own flag
instead of global ftrace enable flag.

Only function traces can be exported to other destinations currently.
This patch exports event trace as well. Move trace export related
function to the beginning of file so other trace can call
trace_process_export() to export.
