The delayed write buffer split trace currently issues a trace for
every buffer it scans. These buffers are not necessarily queued for
delayed write. Indeed, when buffers are pinned, there can be
thousands of traces of buffers that aren't actually queued for
delayed write and the ones that are are lost in the noise. Move the
trace point to record only buffers that are split out for IO to be
issued on.

This patch attempts to make the perf trace command-line for live-mode
commands more user-friendly and consistent with other perf commands.
The main change it makes is to allow <commands> to be run as part of
perf trace live-mode commands, as other perf commands do, instead of
the system-wide traces they're currently hard-coded to by the shell
scripts.
With this patch, the following live-mode trace now works as expected:
$ perf trace rw-by-pid ls -al
The previous system-wide behavior for this command would still be
available by explicitly specifying -a:
$ perf trace rw-by-pid -a ls -al
and if no <command> is specified, the output is also system-wide:
$ perf trace rw-by-pid
Because live-mode requires both record and report steps to be invoked,
it isn't always possible to know which args to send to the report and
which to send to the record steps - mainly this is the case for report
scripts with optional args - in those cases it would be necessary to
use separate 'perf trace record' and 'perf trace report' steps.
For example:
$ perf trace syscall-counts ls
Here we can't decide whether ls should be passed as a param to the
syscall-counts script or whether we should invoke ls as a <command>.
In these cases, we just say that we'll ignore optional script params
and always interpret the extra arguments as a <command>.
If the user instead wants the other interpretation, that can be
accomplished by using separate record and report commands explicitly:
$ perf trace record syscall-counts
$ perf trace report syscall-counts ls
So the rules that this patch implements, which seem to make the most
intuitive sense for live-mode commands:
- for commands with optional args and commands with no args, no args
are sent to the report script, all are sent to the record step
- for 'top' commands i.e. that end with 'top', <commands> can't be
used - all extra args are send to the report script as params
- for commands with required args, the n required args are taken to be
the first n args after the script name and sent to the report
script, and the rest are sent to the record step

Because the perf-trace shell scripts hard-coded the use of the
perf-record system-wide param, a perf trace record session was always
system wide, even if it was given a command.
If given a command, perf trace record now only records the events for
the command, as users expect.
If no command is given, or if the '-a' option is used, the recorded
events are system-wide, as before.

profile_cpu was left over from an earlier implementation that
supported running perf top on a single CPU. profile_cpu was no
longer set by any switch and usages of it resulted in dead code.

As pointed out by Linus, commit dab5855 ("perf_counter: Add mmap event hooks to
mprotect()") is fundamentally wrong as mprotect_fixup() can free 'vma' due to
merging. Fix the problem by moving perf_event_mmap() hook to
mprotect_fixup().
Note: there's another successful return path from mprotect_fixup() if old
flags equal to new flags. We don't, however, need to call
perf_event_mmap() there because 'perf' already knows the VMA is
executable.

native_apic_msr_read() and x2apic_enabled() use rdmsr(msr, low, high),
but only use the low part.
gcc4.6 complains about this:
.../apic.h:144:11: warning: variable 'high' set but not used [-Wunused-but-set-variable]
rdmsr() is just a wrapper around rdmsrl() which splits the 64bit value
into low and high, so using rdmsrl() directly solves this.
[tglx: Changed the variables to u64 as suggested by Cyrill. It's less
confusing and has no code impact as this is 64bit only anyway.
