Because in 'perf top' we'll need to parse just once and then, as samples
come, render multiple times with evolving counter values.

The perf annotate tool continues aggregating everything on just one
histograms, but to support the top model add support for one histogram
perf evsel in the evlist.

They will be used by perf top, so that we have just one set of routines
to do annotation.
Rename "struct sym_priv" to "struct annotation", etc, to clarify this
code a bit.
Rename "struct sym_ext" to "struct source_line", to give it a meaningful
name, that clarifies that it is a the result of an addr2line call, that
is sorted by percentage one particular source code line appeared in the
annotation.
And since we're moving things around also rename 'sym_hist->ip' to
'sym_hist->addr' as we want to do data structure annotation at some
point.

Oleg reported that on architectures with
__ARCH_WANT_INTERRUPTS_ON_CTXSW the IPI from
task_oncpu_function_call() can land before perf_event_task_sched_in()
and cause interesting situations for eg. perf_install_in_context().
This patch reworks the task_oncpu_function_call() interface to give a
more usable primitive as well as rework all its users to hopefully be
more obvious as well as remove the races.
While looking at the code I also found a number of races against
perf_event_task_sched_out() which can flip contexts between tasks so
plug those too.

Allow non-ARM SMP processors to use the SMP_ON_UP feature. CPUs
supporting SMP must have the new CPU ID format, so check for this first.
Then check for ARM11MPCore, which fails the MPIDR check. Lastly check
the MPIDR reports multiprocessing extensions and that the CPU is part of
a multiprocessing system.

So that we don't have to pass it around to the several methods that
needs it, simplifying usage.
There is one case where we don't have the thread/cpu map in advance,
which is in the parsing routines used by top, stat, record, that we have
to wait till all options are parsed to know if a cpu or thread list was
passed to then create those maps.
For that case consolidate the cpu and thread map creation via
perf_evlist__create_maps() out of the code in top and record, while also
providing a perf_evlist__set_maps() for cases where multiple evlists
share maps or for when maps that represent CPU sockets, for instance,
get crafted out of topology information or subsets of threads in a
particular application are to be monitored, providing more granularity
in specifying which cpus and threads to monitor.

Disable the initrd if the passed address already overlaps the reserved
region. This avoids oopses on Netwinders when NeTTrom tells the kernel
that an initrd is located at mem+4MB, but this overlaps the BSS,
resulting in the kernels in-use BSS being freed.
This should be applied to v2.6.37-stable.

In ntfs_mft_record_alloc() when mapping the new extent mft record with
map_extent_mft_record() we overwrite @m with the return value and on
error, we then try to use the old @m but that is no longer there as @m
now contains an error code instead so we crash when dereferencing the
error code as if it were a pointer.
The simple fix is to use a temporary variable to store the return value
thus preserving the original @m for later use. This is a backport from
the commercial Tuxera-NTFS driver and is well tested...
Thanks go to Julia Lawall for pointing this out (whilst I had fixed it
in the commercial driver I had failed to fix it in the Linux kernel).

They were on evsel.c because they came from refactoring existing evsel
methods, so, to make reviewing the changes easier, I kept it there, now
its a plain move.

First clarifying that this kind of binding is not a replacement or an
equivalent to the 'perf script' way of using python with perf.
The 'perf script' way is to process events and look at a given script
for some python function that matches the events to pass each event for
processing.
This is a python module, i.e. everything is driven from the python
script, that merely uses "import perf" or "from perf import".
perf script is focused on tracepoints, this binding is focused on profiling as
an initial target. More work is needed to make available tracepoint specific
variables as event variables accessible via this binding.
There is one example of such usage model, in
tools/perf/python/twatch.py, a tool to watch "cycles" events together
with task (fork, exit) and comm perf events.
For now, due to me not being able to grok how python distutils cope with
building C extensions outside the sources dir the install target just
builds it, I'm using it as:
[root@emilia linux]# export PYTHONPATH=~acme/git/build/perf/lib.linux-x86_64-2.6/
[root@emilia linux]# tools/perf/python/twatch.py
cpu: 4, pid: 30126, tid: 30126 { type: mmap, pid: 30126, tid: 30126, start: 0x4, length: 0x82e9ca03, offset: 0, filename: }
cpu: 6, pid: 47, tid: 47 { type: mmap, pid: 47, tid: 47, start: 0x6, length: 0xbef87c36, offset: 0, filename: }
cpu: 1, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0x1, length: 0x775d1904, offset: 0, filename: }
cpu: 7, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0x7, length: 0xc750aeb6, offset: 0, filename: }
cpu: 5, pid: 2255, tid: 2255 { type: mmap, pid: 2255, tid: 2255, start: 0x5, length: 0x76669635, offset: 0, filename: }
cpu: 0, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0, length: 0x6422ef6b, offset: 0, filename: }
cpu: 2, pid: 2255, tid: 2255 { type: mmap, pid: 2255, tid: 2255, start: 0x2, length: 0xe078757a, offset: 0, filename: }
cpu: 1, pid: 5769, tid: 5769 { type: fork, pid: 30127, ppid: 5769, tid: 30127, ptid: 5769, time: 103893991270534}
cpu: 6, pid: 30127, tid: 30127 { type: comm, pid: 30127, tid: 30127, comm: ls }
cpu: 6, pid: 30127, tid: 30127 { type: exit, pid: 30127, ppid: 30127, tid: 30127, ptid: 30127, time: 103893993273024}
The first 8 mmap events in this 8 way machine are a mistery that is still being
investigated.
More of the tools/perf/util/ APIs will be exposed via this python binding as
the need arises. For now the focus is on creating events and processing them,
symbol resolution is an obvious next step, with tracepoint variables as a close
second step.

And move the event_t methods to the perf_event__ too.
No code changes, just namespace consistency.
