In ramoops_pstore_read, a valid prz pointer with zero size buffer will
break traverse of all persistent ram buffers. The latter buffer might
be lost.

pnp pnp_bus_suspend/_resume have an issue.
pnp_bus_suspend calls pnp_stop_dev to disable the device. With ACPI,
pnp_stop_dev turns off the dev usually. Then,
pnp_bus_suspend=>pnp_dev->protocol->suspend accesses the device and
suspend it again.
pnp_bus_resume has the similar is
From: Liu ShuoX
Set temporary variable as 0 to avoid garbage string output from
/proc/iomem after register resources, and reset to pnp dev name.

In shutdown progress, system is possible to do power transition
(such as suspend-to-ram) in parallel. It is unreasonable. So,
fixes it by adding a system_state checking and queue try_to_suspend
again when system status is not running.

dpm_run_callback is used in other stages of power states changing.
It provides debug info message and time measurement when call these

synchronize_irq waits pending IRQ handlers to be finished. If using this
function while holding a resource, the IRQ handler may cause deadlock.
Here we add a new function irq_in_progress which doesn't wait for the handlers
to be finished.
A typical use case at suspend-to-ram:

perf/x86: Enable Intel
From: ShuoX Liu
This boolean function simply returns whether or not the runtime
status of the device is 'active'. The typical scenario is driver
calls pm_runtime_get firstly, then check pm_runtime_active in
atomic environment.
Also add entry to Documentation/power/runtime.txt

These three chip are based on Atom and have different model id.
So add such three id for perf HW event support.

syscore_shutdown uses initcall_debug to control the debug info output.
It’s a good programming. But device_shutdown doesn’t. The patch changes
device_shutdown to follow the style.
