Userspace thermal daemon initiate KTM hotplug monitor related
initialization. Thermal core control can be disabled/enabled from
userspace via KTM sysfs for cpu related initialization after boot.
There is a possible race condition between KTM hotplug initialization
from thermal daemon and KTM core control re-enablement from userpsace
shell. When these both events are triggered at the same time,
thermal core control enablement tries to set emergency hotplug
threshold prior to per cpu hotplug related initialization like sensor
id, trip and threshold value etc. This leads to wrong sensor
threshold settings and eventually thermal core sensor threshold list
will be broken.
To avoid this wrong threshold settings during thermal core control
enablement, check KTM hotplug related initialization is done prior
to threshold setting for each core.

Commit 761ed4a94582 ("tty: serial_core: convert uart_close to use
tty_port_close") created a case where a port used for a console does not
get shutdown on tty closing. Then a call to uart_tx_stopped() segfaults
because the tty is NULL. This could be fixed to restore old behavior,
but we also want to allow tty_ports to work without a tty attached. So
this change to allow a NULL tty_struct is needed either way.

The stacktraces always begin as follows:
[<c00117b4>] save_stack_trace_tsk+0x0/0x98
[<c0011870>] save_stack_trace+0x24/0x28
...
This is because the stack trace code includes the stack frames for itself.
This is incorrect behaviour, and also leads to "skip" doing the wrong
thing (which is the number of stack frames to avoid recording.)
Perversely, it does the right thing when passed a non-current thread. Fix
this by ensuring that we have a known constant number of frames above the
main stack trace function, and always skip these.
This was fixed for arch arm by 3683f44c42 ("ARM: stacktrace: avoid
listing stacktrace functions in stacktrace")
