While not working as an I2C device, USB3503 chip needs to be reset
after the USB PHY has been initialized for this to work properly.
Currently there is no other way to ensure that USB3503 chip is probed
after the USB PHY has been initialized, hence the last resort.

This adds core support for saving and restoring CPU PMU registers
for suspend/resume support i.e. deeper C-states in cpuidle terms.
This patch adds support only to ARMv7 PMU registers save/restore.
It needs to be extended to xscale and ARMv6 if needed.

The userspace perf tool provides options to specify PMU names from command
line for the event. An example of pmu event syntax would be
(<pmu_name>/<config>/<modifier>)
However the parser in the perf tool breaks the tokens at spacesand fails to
identify the PMU name with spaces correctly.
This patch removes spaces in the ARMv7 CPU PMU names.

In a system with multiple heterogeneous CPU PMUs and each PMUs can handle
events on a subset of CPUs, probably belonging a the same cluster.
This patch introduces a cpumask to track which CPUs each PMU supports.
It also updates armpmu_event_init to reject cpu-specific events being
initialised for unsupported CPUs. Since process-specific events can be
initialised for all the CPU PMUs,armpmu_start/stop/add are modified to
prevent from being added on unsupported CPUs.

In order to support multiple, heterogeneous CPU PMUs and distinguish
them, they cannot be registered as PERF_TYPE_RAW type. Instead we can
get perf core to allocate a new idr type id for each PMU.
Userspace applications can refer sysfs entried to find a PMU's type,
which can then be used in tracking events on individual PMUs.

A single global CPU PMU pointer is not useful in a system with multiple,
heterogeneous CPU PMUs as we need to access the relevant PMU depending
on the current CPU.
This patch replaces the single global CPU PMU pointer with per-cpu
pointers and changes the OProfile accessors to refer to the PMU affine
to CPU0.

Some device drivers like PMU require to retrieve the logical cpu mask
that corresponds to a given cluster id. This patch provides a hook in
the topology code that, given an existing cluster id as input,
initializes the corresponding cpumask passed as a pointer, reusing all
existing topology information required by sched domains in the kernel.

Pull tracing fix from Steven Rostedt:
"A regression showed up that there's a large delay when enabling all
events. This was prevalent when FTRACE_SELFTEST was enabled which
enables all events several times, and caused the system bootup to
pause for over a minute.
This was tracked down to an addition of a synchronize_sched()
performed when system call tracepoints are unregistered.
The synchronize_sched() is needed between the unregistering of the
system call tracepoint and a deletion of a tracing instance buffer.
But placing the synchronize_sched() in the unreg of *every* system
call tracepoint is a bit overboard. A single synchronize_sched()
before the deletion of the instance is sufficient"

It has been reported that boot up with FTRACE_SELFTEST enabled can take a
very long time. There can be stalls of over a minute.
This was tracked down to the synchronize_sched() called when a system call
event is disabled. As the self tests enable and disable thousands of events,
this makes the synchronize_sched() get called thousands of times.
The synchornize_sched() was added with d562aff93bfb53 "tracing: Add support
for SOFT_DISABLE to syscall events" which caused this regression (added
in 3.13-rc1).
The synchronize_sched() is to protect against the events being accessed
when a tracer instance is being deleted. When an instance is being deleted
all the events associated to it are unregistered. The synchronize_sched()
makes sure that no more users are running when it finishes.
Instead of calling synchronize_sched() for all syscall events, we only
need to call it once, after the events are unregistered and before the
instance is deleted. The event_mutex is held during this action to
prevent new users from enabling events.
