ef366c8b57 ARM: dts: msm: Add support for pwr/perf supply for sdm660 
OSM cpu clocks would require the supply rails on which power and perf
clusters are connected, so add the same.

e4434f152e ARM: dts: msm: Add an entry to the Silver memlat table for msm8998 
Add a level at the lower end of the memlat table for the Silver
cluster so that the memlat driver votes for at least 200MHz
when the CPU's effective frequency is at most 300MHz for latency
bound workloads.

103f5f9265 clk: qcom: osm: remove ioremaps from panic callback 
Calling ioremap() in clk_osm_panic_callback() can result in
BUG() when the kernel is panic-ing. It is not safe to use
ioremap() in atomic context. Map the debug registers at probe
time instead.

f43931e819 sched: Delete heavy task heuristics in prediction code 
Heavy task prediction code needs further tuning to avoid any
negative power impact. Delete the code for now instead of adding
tunables to avoid inefficiencies in the scheduler path.

1b0631a740 ppp: take reference on channels netns 
Let channels hold a reference on their network namespace.
Some channel types, like ppp_async and ppp_synctty, can have their
userspace controller running in a different namespace. Therefore they
can't rely on them to preclude their netns from being removed from
under them.
