msm: kgsl: Add the buffer user address to the debugfs memory list

For each buffer in the debugfs memory list print the address it is
mapped to in the user process.  This is useful for matching up the
user side allocations with what the kernel thinks it has.

msm: kgsl: use %pK to restrict printing GPU / memory addresses

Use %pK in the output for the per-process memory dump to keep from
printing the GPU and user memory addresses for the GPU memory
objects own by the process.  This allows us to make the 'mem' file
world readable without exposing any really dangerous information.

msm_fb: Register frame buffer device for device shutdown

Many display panels have a requirement of executing panel-off
commands when the device goes to shutdown. Hence, register frame
buffer device for device shutdown so that the panel-off commands
can be executed successfully.

misc: qfpfuse: Fix overflow condition

Fix potential integer overflow for ioctl command to avoid incorrect
buffer allocation. Use the stack for data buffering to avoid the
small buffer allocation for improved performance. Increase the fuse
blow timeout in the driver to cover all QFPROM implementations

diag: Remove error message

Some diag messages are marked as error messages which should
be marked as debug. This patch fixes that issue.

Perf: Check perf activity on correct CPU

The CPU hotplug notifier is not always preempt safe.
So relying on smp_processor_id() is not correct.

Use the cpu id from the notifier as the target
CPU to check for perf activity before hotplug or power
collapse.

Perf: Add L1 counters to tracepoints

Create a new tracepoint to get L1 PMU counter
information at every context switch. Counters
are captured only when the tracepoint is enabled
via perf or ftrace.

Perf: Fix counts across power collapse

After entry and exit from power collapse, the perf pm_notifier was
calling perf_pmu_disable/enable functions from perf core. Perf core
maintains a counter that it uses to match disable and enable calls but
since pm_notifier is invoked asynchronously, the counter was getting a
non-zero value which prevented the pmu from being enabled. As a result of
this, we were seeing zero counts for some cores across power collapse.

Make the architecture specific calls directly from pm_notifier.
