Now that dma_get_[base/size] are not needed by other
drivers, remove the implementation of dma_get_size(),
and limit the scope of dma_get_base() to its original
visibility.

Use of_address_to_resource() to get the carveout base and size
in one shot. This also simplifies the error handling by allowing
us to decrement the reference count on the of_node in one place,
as opposed to two places.

Remove the usage of [cma/dma]_get_[base/size], as they
serve no functional purpose in the MSM ION driver at the
moment.

Qualcomm Technologies Inc's (QTI) chipsets support SoC level
low power modes. Statistics for SoC sleep stats are produced
by remote processor.
Lets's add a driver to read the shared memory exported by the
remote processor and export to sysfs.

Since we don't do energy-aware wakeups when we are overutilized, always
honoring sync wakeups in this state does not prevent wake-wide mechanics
overruling the flag as normal.
Having the check for (cpu_rq(cpu)->nr_running == 1) in the test condition
means that we only bypass the energy model for sync wakeups where the
cpu is about to become idle. This matches the use of this flag in Binder
which is the main place where sync wakeups come from in Android.
This patch is based upon previous work to build EAS for android products.
It replaces
commit 79e3a4a27e ("ANDROID: sched: Unconditionally honor sync flag
for energy-aware wakeups")
in what's considered to be 'EAS'.

The generic kernel image must have module signing disabled so it can
load kernel modules from all vendors. Unfortunately loading a signed
kernel module into a kernel with module signing disabled will fail
because struct module_layout (which appears in kernel modules) contains
struct module, and struct module contains the sig_ok field, which is
conditionally compiled depending on CONFIG_MODULE_SIG (module signing).
Unconditionally compile the sig_ok field to work around this problem.

Soc framework exposed sysfs entries are not sufficient for some
of the h/w platforms. Currently there is no interface where soc
drivers can expose further information about their SoCs via soc
framework. This change address this limitation where clients can
pass their custom entries as attribute group and soc framework
would expose them as sysfs properties.

There are scenarios where a rate change could result in a configuration
change for both the targeted clock and its parent.
For example, setting the rate for a clock could require both slewing its parent
PLL as well as adjusting the clock's divider values. Due to the fact that
rate change propagation always occurs from parent to child, we could exceed
the allowed operating frequencies for the clock as the parent slews to a higher
frequency before increasing the downstream divider.
Add a pre change call back which allows the clock to adjust its divider
appropriately before any rate change has occurred from its parents to ensure
that the clock's requirements are always within safe frequencies during parent
rate changes. The symmetrical post change call back handles the scenario where
the divider adjusts to a lower value and can only be safely adjusted after the
parent rate changes.

- Removed locked down from tracefs itself and moved it to the trace
directory. Having the open functions there do the lockdown checks.
- Fixed a few races with opening an instance file and the instance being
deleted (Discovered during the locked down updates). Kept separate
from the clean up code such that they can be backported to stable
easier.
- Cleaned up and consolidated the checks done when opening a trace
file, as there were multiple checks that need to be done, and it
did not make sense having them done in each open instance.
- Fixed a regression in the record mcount code.
- Small hw_lat detector tracer fixes.
- A trace_pipe read fix due to not initializing trace_seq.

It caught the process in the middle of trace_access_unlock(). There is
no loop. So, it must be looping in the caller tracing_read_pipe()
via the "waitagain" label.
Crashdump analyze uncovered that iter->seq was completely zeroed
at this point, including iter->seq.seq.size. It means that
print_trace_line() was never able to print anything and
there was no forward progress.
The culprit seems to be in the code:
/* reset all but tr, trace, and overruns */
memset(&iter->seq, 0,
sizeof(struct trace_iterator) -
offsetof(struct trace_iterator, seq));
It was added by the commit 53d0aa7730 ("ftrace:
add logic to record overruns"). It was v2.6.27-rc1.
It was the time when iter->seq looked like:
struct trace_seq {
unsigned char buffer[PAGE_SIZE];
unsigned int len;
};
There was no "size" variable and zeroing was perfectly fine.
The solution is to reinitialize the structure after or without
zeroing.

max_latency is intended to record the maximum ever observed hardware
latency, which may occur in either part of the loop (inner/outer). So
we need to also consider the outer-loop sample when updating
max_latency.

nmi_total_ts is supposed to record the total time spent in *all* NMIs
that occur on the given CPU during the (active portion of the)
sampling window. However, the code seems to be overwriting this
variable for each NMI, thereby only recording the time spent in the
most recent NMI. Fix it by accumulating the duration instead.

The removal of the longjmp code in recordmcount.c mistakenly made the return
of make_nop() being negative an exit of nop_mcount(). It should not exit the
routine, but instead just not process that part of the code. By exiting with
an error code, it would cause the update of recordmcount to fail some files
which would fail the build if ftrace function tracing was enabled.

If on boot up, lockdown is activated for tracefs, don't even bother creating
the files. This can also prevent instances from being created if lockdown is
in effect.

Added various checks on open tracefs calls to see if tracefs is in lockdown
mode, and if so, to return -EPERM.
Note, the event format files (which are basically standard on all machines)
as well as the enabled_functions file (which shows what is currently being
traced) are not lockde down. Perhaps they should be, but it seems counter
intuitive to lockdown information to help you know if the system has been
modified.

Currently, most files in the tracefs directory test if tracing_disabled is
set. If so, it should return -ENODEV. The tracing_disabled is called when
tracing is found to be broken. Originally it was done in case the ring
buffer was found to be corrupted, and we wanted to prevent reading it from
crashing the kernel. But it's also called if a tracing selftest fails on
boot. It's a one way switch. That is, once it is triggered, tracing is
disabled until reboot.
As most tracefs files can also be used by instances in the tracefs
directory, they need to be carefully done. Each instance has a trace_array
associated to it, and when the instance is removed, the trace_array is
freed. But if an instance is opened with a reference to the trace_array,
then it requires looking up the trace_array to get its ref counter (as there
could be a race with it being deleted and the open itself). Once it is
found, a reference is added to prevent the instance from being removed (and
the trace_array associated with it freed).
Combine the two checks (tracing_disabled and trace_array_get()) into a
single helper function. This will also make it easier to add lockdown to
tracefs later.
