Extend the perf_pmu_register() interface to allow for named and
dynamic pmu types.Because we need to support the existing static types we cannot use
dynamic types for everything, hence provide a type argument.If we want to enumerate the PMUs they need a name, provide one.

Introduce perf_pmu_name() helper function that returns the name of the
pmu. This gives us a generic way to get the name of a pmu regardless of
how an architecture identifies it internally.Signed-off-by: Matt Fleming

Replace pmu::{enable,disable,start,stop,unthrottle} with
pmu::{add,del,start,stop}, all of which take a flags argument.The new interface extends the capability to stop a counter while
keeping it scheduled on the PMU. We replace the throttled state with
the generic stopped state.This also allows us to efficiently stop/start counters over certain
code paths (like IRQ handlers).It also allows scheduling a counter without it starting, allowing for
a generic frozen state (useful for rotating stopped counters).The stopped state is implemented in two different ways, depending on
how the architecture implemented the throttled state:1) We disable the counter:
a) the pmu has per-counter enable bits, we flip that
b) we program a NOP event, preserving the counter state2) We store the counter state and ignore all read/overflow events

Since the current perf_disable() usage is only an optimization,
remove it for now. This eases the removal of the __weak

Remove the hw_perf_event_*() hotplug hooks in favour of per PMU hotplug
notifiers. This has the advantage of reducing the static weak interface
as well as exposing all hotplug actions to the PMU.Use this to fix x86 hotplug usage where we did things in ONLINE which
should have been done in UP_PREPARE or STARTING.Signed-off-by: Peter Zijlstra

This adds in preliminary support for the SH-4A performance counters.
Presently only the first 2 counters are supported, as these are the ones
of the most interest to the perf tool and end users. Counter chaining is
not presently handled, so these are simply implemented as 32-bit
counters.This also establishes a perf event support framework for other hardware
counters, which the existing SH-4 oprofile code will migrate over to as
the SH-4A support evolves.Signed-off-by: Paul Mundt
