7e5b2db77b Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
 "The whole series has been sitting in -next for quite a while with no
  complaints.  The last change to the series was before the weekend the
  removal of an SPI patch which Grant - even though previously acked by
  himself - appeared to raise objections.  So I removed it until the
  situation is clarified.  Other than that all the patches have the acks
  from their respective maintainers, all MIPS and x86 defconfigs are
  building fine and I'm not aware of any problems introduced by this
  series.

  Among the key features for this patch series is a sizable patchset for
  Lantiq which among other things introduces support for Lantiq's
  flagship product, the FALCON SOC.  It also means that the opensource
  developers behind this patchset have overtaken Lantiq's competing
  inhouse development team that was working behind closed doors.

  Less noteworthy the ath79 patchset which adds support for a few more
  chip variants, cleanups and fixes.  Finally the usual dose of tweaking
  of generic code."

Fix up trivial conflicts in arch/mips/lantiq/xway/gpio_{ebu,stp}.c where
printk spelling fixes clashed with file move and eventual removal of the
printk.

fd0d000b2c perf: Pass last sampling period to perf_sample_data_init()
We always need to pass the last sample period to
perf_sample_data_init(), otherwise the event distribution will be
wrong. Thus, modifiyng the function interface with the required period
as argument. So basically a pattern like this:

        perf_sample_data_init(&data, ~0ULL);
        data.period = event->hw.last_period;

will now be like that:

        perf_sample_data_init(&data, ~0ULL, event->hw.last_period);

Avoids unininitialized data.period and simplifies code.

266623b759 MIPS/Perf-events: Remove pmu and event state checking in validate_event()
Why removing pmu checking:
Since 3.2-rc1, when arch level event init is called, the event is already
connected to its PMU. Also, validate_event() is _only_ called by
validate_group() in event init, so there is no need of checking or
temporarily assigning event pmu during validate_group().

Why removing event state checking:
Events could be created in PERF_EVENT_STATE_OFF (attr->disabled == 1), when
these events go through this checking, validate_group() does dummy work.
But we do need to do group scheduling emulation for them in event init.
Again, validate_event() is _only_ called by validate_group().

74653ccf23 MIPS/Perf-events: Remove erroneous check on active_events
Port the following patch for ARM by Mark Rutland:

- 57ce9bb39b
    ARM: 6902/1: perf: Remove erroneous check on active_events

    When initialising a PMU, there is a check to protect against races with
    other CPUs filling all of the available event slots. Since armpmu_add
    checks that an event can be scheduled, we do not need to do this at
    initialisation time. Furthermore the current code is broken because it
    assumes that atomic_inc_not_zero will unconditionally increment
    active_counts and then tries to decrement it again on failure.

    This patch removes the broken, redundant code.

2c1b54d331 MIPS/Perf-events: Don't do validation on raw events
MIPS licensees may want to modify performance counters to count extra
events. Also, now that the user is working on raw events, the manual is
being used for sure. And feeding unsupported events shouldn't cause
hardware failure and the like.

[ralf@linux-mips.org: performance events also being used in internal
performance evaluation and have a tendency to change as the micro-
architecture evolves, even for minor revisions that may not be
distinguishable by PrID.  It's not very practicable to maintain a list
of all events and there is no real benefit.]

82091564cf MIPS: perf: Add support for 64-bit perf counters.
The hard coded constants are moved to struct mips_pmu.  All counter
register access move to the read_counter and write_counter function
pointers, which are set to either 32-bit or 64-bit access methods at
initialization time.

Many of the function pointers in struct mips_pmu were not needed as
there was only a single implementation, these were removed.

I couldn't figure out what made struct cpu_hw_events.msbs[] at all
useful, so I removed it too.

Some functions and other declarations were reordered to reduce the
need for forward declarations.

e5dcb58aa5 MIPS: perf: Reorganize contents of perf support files.
The contents of arch/mips/kernel/perf_event.c and
arch/mips/kernel/perf_event_mipsxx.c were divided in a seemingly ad
hoc manner, with the first including the second.

I moved all the hardware counter support code to perf_event_mipsxx.c
and removed the gating #ifdefs to the Kconfig and Makefile.

Now perf_event.c contains only the callchain support, everything else
is in perf_event_mipsxx.c

There are no code changes, only moving of functions from one file to
the other, or removing empty unneeded functions.

89d6c0b5bd perf, arch: Add generic NODE cache events
Add a NODE level to the generic cache events which is used to measure
local vs remote memory accesses. Like all other cache events, an
ACCESS is HIT+MISS, if there is no way to distinguish between reads
and writes do reads only etc..

The below needs filling out for !x86 (which I filled out with
unsupported events).

I'm fairly sure ARM can leave it like that since it doesn't strike me as
an architecture that even has NUMA support. SH might have something since
it does appear to have some NUMA bits.

Sparc64, PowerPC and MIPS certainly want a good look there since they
clearly are NUMA capable.

404ff63840 MIPS, Perf-events: Work with the new PMU interface
This is the MIPS part of the following commits by Peter Zijlstra:

- a4eaf7f146
    perf: Rework the PMU methods

    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 state

     2) We store the counter state and ignore all read/overflow events

For MIPSXX, the stopped state is implemented in the way of 1.b as above.

- 33696fc0d1
    perf: Per PMU disable

    Changes perf_disable() into perf_pmu_disable().

- 24cd7f54a0
    perf: Reduce perf_disable() usage

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

- b0a873ebbf
    perf: Register PMU implementations

    Simple registration interface for struct pmu, this provides the
    infrastructure for removing all the weak functions.

- 51b0fe3954
    perf: Deconstify struct pmu

    sed -ie 's/const struct pmu\>/struct pmu/g' `git grep -l "const struct pmu\>"`

91f017372a MIPS, Perf-events: Work with irq_work
This is the MIPS part of the following commit by Peter Zijlstra:

- e360adbe29
    irq_work: Add generic hardirq context callbacks

    Provide a mechanism that allows running code in IRQ context. It is
    most useful for NMI code that needs to interact with the rest of the
    system -- like wakeup a task to drain buffers.

    Perf currently has such a mechanism, so extract that and provide it as
    a generic feature, independent of perf so that others may also
    benefit.

    The IRQ context callback is generated through self-IPIs where
    possible, or on architectures like powerpc the decrementer (the
    built-in timer facility) is set to generate an interrupt immediately.

    Architectures that don't have anything like this get to do with a
    callback from the timer tick. These architectures can call
    irq_work_run() at the tail of any IRQ handlers that might enqueue such
    work (like the perf IRQ handler) to avoid undue latencies in
    processing the work.

For MIPSXX, we need to call irq_work_run() at the tail of the perf IRQ
handler as described above.

004417a6d4 perf, arch: Cleanup perf-pmu init vs lockup-detector
The perf hardware pmu got initialized at various points in the boot,
some before early_initcall() some after (notably arch_initcall).

The problem is that the NMI lockup detector is ran from early_initcall()
and expects the hardware pmu to be present.

Sanitize this by moving all architecture hardware pmu implementations to
initialize at early_initcall() and move the lockup detector to an explicit
initcall right after that.

3a9ab99e03 MIPS: Add support for hardware performance events (mipsxx)
This patch adds the mipsxx Perf-events support based on the skeleton.
Generic hardware events and cache events are now fully implemented for
the 24K/34K/74K/1004K cores. To support other cores in mipsxx (such as
R10000/SB1), the generic hardware event tables and cache event tables
need to be filled out. To support other CPUs which have different PMU
than mipsxx, such as RM9000 and LOONGSON2, the additional files
perf_event_$cpu.c need to be created.

Raw event is an important part of Perf-events. It helps the user collect
performance data for events that are not listed as the generic hardware
events and cache events but ARE supported by the CPU's PMU.

This patch also adds this feature for mipsxx 24K/34K/74K/1004K. For how to
use it, please refer to processor core software user's manual and the
comments for mipsxx_pmu_map_raw_event() for more details.

Please note that this is a "precise" implementation, which means the
kernel will check whether the requested raw events are supported by this
CPU and which hardware counters can be assigned for them.

To test the functionality of Perf-event, you may want to compile the tool
"perf" for your MIPS platform. You can refer to the following URL:
http://www.linux-mips.org/archives/linux-mips/2010-10/msg00126.html

You also need to customize the CFLAGS and LDFLAGS in tools/perf/Makefile
for your libs, includes, etc.

In case you encounter the boot failure in SMVP kernel on multi-threading
CPUs, you may take a look at:
