mem-loads is basically the same as Sandy Bridge,
but we use a separate string for changes later.

Haswell doesn't support the full precise store mode,
so we emulate it using the "DataLA" facility.
This allows to do everything, but for data sources we
can only detect L1 hit or not.

There is no explicit enable bit anymore, so we have
to tie it to a perf internal only flag.

The address is supported for all memory related PEBS
events with DataLA. Instead of only logging for the
load and store events we allow logging it for all
(it will be simply 0 if the current event does not
support it)

Haswell has two additional LBR from flags for TSX: in_tx and
abort_tx, implemented as a new "v4" version of the LBR format.

Handle those in and adjust the sign extension code to still
correctly extend. The flags are exported similarly in the LBR
record to the existing misprediction flag

This avoids some problems with spurious PMIs on Haswell.
Haswell seems to behave more like P4 in this regard. Do
the same thing as the P4 perf handler by unmasking
the NMI only at the end. Shouldn't make any difference
for earlier family 6 cores.

(Tested on Haswell, IvyBridge, Westmere, Saltwell (Atom).)

Similar to SandyBridge, but has a few new events and two

There are some new counter flags that need to be prevented
from being set on fixed counters, and allowed to be set
for generic counters.

Also we add support for the counter 2 constraint to handle
all raw events.

Add support for the Haswell extended (fmt2) PEBS format.

It has a superset of the nhm (fmt1) PEBS fields, but has a
longer record so we need to adjust the code paths.

The main advantage is the new "EventingRip" support which
directly gives the instruction, not off-by-one instruction. So
with precise == 2 we use that directly and don't try to use LBRs
and walking basic blocks. This lowers the overhead of using
precise significantly.

Some other features are added in later patches.

Implement a perf PMU to handle IOMMU performance counters and events.
The PMU only supports counting mode (e.g. perf stat). Since the counters
are shared across all cores, the PMU is implemented as "system-wide" mode.

To invoke the AMD IOMMU PMU, issue a perf tool command such as:

  ./perf stat -a -e amd_iommu/<events>/ <command>

or:

  ./perf stat -a -e amd_iommu/config=<config-data>,config1=<config1-data>/ <command>

For example:

  ./perf stat -a -e amd_iommu/mem_trans_total/ <command>

The resulting count will be how many IOMMU total peripheral memory
operations were performed during the command execution window.

intel_pmu_handle_irq() has a warning in it if it does too many
loops.  It is a WARN_ONCE(), but the perf_event_print_debug()
call beneath it is unconditional. For the first warning, you get
a nice backtrace and message, but subsequent ones just dump the
PMU state with no leading messages.  I doubt this is what was
intended.

This patch will only print the PMU state when paired with the
WARN_ON() text.  It effectively open-codes WARN_ONCE()'s
one-time-only logic.

My suspicion is that the code really just wants to make sure we
do not sit in the loop and spit out a warning for every loop
iteration after the 100th.  From what I've seen, this is very
unlikely to happen since we also clear the PMU state.

After this patch, instead of seeing the PMU state dumped each
time, you will just see:

x86_schedule_events() caches event constraints on the stack during
scheduling.  Given the number of possible events, this is 512 bytes of
stack; since it can be invoked under schedule() under god-knows-what,
this is causing stack blowouts.

Trade some space usage for stack safety: add a place to cache the
constraint pointer to struct perf_event.  For 8 bytes per event (1% of
its size) we can save the giant stack frame.

This shouldn't change any aspect of scheduling whatsoever and while in
theory the locality's a tiny bit worse, I doubt we'll see any
performance impact either.

Tested: `perf stat whatever` does not blow up and produces
results that aren't hugely obviously wrong.  I'm not sure how to run
particularly good tests of perf code, but this should not produce any
functional change whatsoever.

Vince's fuzzer once again found holes. This time it spotted a leak in
the locked page accounting.

When an event had redirected output and its close() was the last
reference to the buffer we didn't have a vm context to undo accounting.

Change the code to destroy the buffer on the last munmap() and detach
all redirected events at that time. This provides us the right context
to undo the vm accounting.

Make it explicit that the format attributes may define overlapping bit
ranges. Unfortunately this was left unspecified originally, and all the
examples show non-overlapping ranges. I don't believe this is an ABI
change, as we are defining something that was previously undefined, but
others may disagree.

The POWER8 PMU would like to define overlapping ranges, as bit ranges in
the event code have different meanings for certain events. It will also
allow us to define an overarching "event" field, that encompasses all
others.

As far as I can see perf is comfortable with this change, however I am
not sure if there are any other users of the interface.

We have a one of the event open fallback case in __perf_evsel__open
where we zero exclude_guest|exclude_host fields.

This means there's no way for attr tests to find out what's the right
value for those fields, so we need to check for both 0 and 1. Luckily we
still have other event parsing tests for those fields.

The sample type for '-d' option is changed, because of the memory
profiling patches from Stephane. The '-d' now adds PERF_SAMPLE_DATA_SRC
sample_type.
