Excessive logging due to several successive memory allocation failure
may cause a watchdog bite. Hence, this change adds ratelimit to logging
on memory allocation failure.

The PM_QOS_CPU_DMA_LATENCY vote attached to an IRQ is discarded,
if it is affined to an isolated CPU. So we need atleast 1 CPU
in online and un-isolate state. The scheduler rejects isolating
a CPU if it is the only online and un-isolated CPU in the system.
Add the same check for CPU hotplug.

when set_cs() is called by framework, first check the device suspend
status and if not suspended then proceed for register access. Let system
suspend call SPI runtime suspend but make sure set_cs doesn't race with
it by holding the mutex.

Defines the non-removable property for UFS device node.
This basically lets the driver know that UFS is the

Adding remote debugger device configuration. The Remote Debugger driver
allows a debugger running on a host PC to communicate with a remote

Add support on dload_mode sysfs entry to select both dumps.
Enable both dumps with command:
echo both > /sys/kernel/dload/dload_mode

pagetypeinfo_showmixedcount_print is found to take a lot of time to
complete and it does this holding the zone lock and disabling interrupts.
In some cases it is found to take more than a second (On a 2.4GHz,8Gb
RAM,arm64 cpu). Avoid taking the zone lock similar to what is done by
read_page_owner, which means possibility of inaccurate results.

[vinmenon@codeaurora.org: fix trivial merge conflicts]

When an attempt is made to free an event on a CPU which is
no longer online, perf tries to bring the CPU online. This
can fail, resulting in an UP_CANCELLED notifier, which
eventually tries to acquire the ctx->mutex which is already
being held by the code, which brings up the CPU.
Removing the attempt to bring the cpu up will remove this
deadlock, but also requires temporarily removing support of
counting events across hotplug. This will be restored in a
later patch.
