This introduces a new thread group flag that can be set by calling
prctl(PR_SET_KILL_DESCENDANTS_ON_EXIT, 1, 0, 0, 0)
When a thread group exits with this flag set, it will send SIGKILL to
all descendant processes. This can be used to prevent stray child
processes.
This flag is cleared on pr
This patch adds a new prctl to kill all descendant processes on exit.

Without this patch, the thermal driver on hi6220 and hi3660 is broken.
That is due because part of the posted patchset was merged but a small

This patch adds Add struct plic_hw to represent global PLIC HW details.
Currently, these details are only used in plic_init() but in-future
these will be useful in implementing PM suspend and resume callbacks.
Further, these global details are good debug info about HW so let's
not throw them away
We make plic_irq_toggle() more generic so that we can enable/disable
hwirq for given cpumask. This generic plic_irq_toggle() will be
eventually used to implement set_affinity for PLIC driver.

We explicitly differentiate between PLIC handler and context because
PLIC context is for given mode of HART whereas PLIC handler is per-CPU
software construct meant for handling interrupts from a particular
PLIC context.
To achieve this differentiation, we rename "nr_handlers" to "nr_contexts"
and
Currently on SMP host, all CPUs take external interrupts routed via
PLIC. All CPUs will try to claim a given external interrupt but only
one of them will succeed while other CPUs would simply resume whatever
they were doing before. This means if we have N CPUs then for every
external interrupt N-1
We have two enteries (one for M-mode and another for S-mode) in the
interrupts-extended DT property of PLIC DT node for each HART. It is
expected that firmware/bootloader will set M-mode HWIRQ line of each
HART to 0x (i.e. -1) in interrupts-extended DT property
because Linux runs in S-mode

The two 'goto setsym' statements are reachable only when sym == NULL.
The code below the 'setsym:' label does nothing when sym == NULL
since there is just one if-block guarded by 'if (sym && ...)'.
Hence, 'goto setsym' can be replaced with 'continue'.

The stpmic1 PMIC embeds a watchdog which is disabled by default. As soon
as the watchdog is started, it must be refreshed periodically otherwise
the PMIC goes off.

The stpmic1 pmic is able to manage an onkey button. This driver exposes
the stpmic1 onkey as an input device. It can also be configured to
shut-down the power supplies on a long key-press with an adjustable
duration.
