perf, x86: Fix hw_perf_enable() event assignment

What happens is that we schedule badly like:

<...>-1987 [019] 280.252811: x86_pmu_start: event-47/1300c0: idx: 1
<...>-1987 [019] 280.252812: x86_pmu_start: event-48/1300c0: idx: 2

<...>-1987 [019] 280.252814: x86_pmu_start: event-50/1300c0: idx: 32
<...>-1987 [019] 280.252825: x86_pmu_stop: event-46/1300c0: idx: 0
<...>-1987 [019] 280.252826: x86_pmu_stop: event-47/1300c0: idx: 1

<...>-1987 [019] 280.252834: x86_pmu_start: event-48/1300c0: idx: 2
<...>-1987 [019] 280.252835: x86_pmu_start: event-49/1300c0: idx: 3
<...>-1987 [019] 280.252836: x86_pmu_start: event-50/1300c0: idx: 32
<...>-1987 [019] 280.252837: x86_pmu_start: event-51/1300c0: idx: 32 *FAIL*

This happens because we only iterate the n_running events in the first
pass, and reset their index to -1 if they don't match to force a
re-assignment.

Now, in our RR example, n_running == 0 because we fully unscheduled, so
event-50 will retain its idx==32, even though in scheduling it will have
gotten idx=0, and we don't trigger the re-assign path.

The easiest way to fix this is the below patch, which simply validates
the full assignment in the second pass.

x86: Improve Intel microcode loader performance

We've noticed that on large SGI UV system configurations,
running microcode.ctl can take very long periods of time. This
is due to the large number of vmalloc/vfree calls made by the
Intel generic_load_microcode() logic.

By reusing allocated space, the following patch reduces the time
to run microcode.ctl on a 1024 cpu system from approximately 80
seconds down to 1 or 2 seconds.

perf: Make the install relative to DESTDIR if specified

Without this change, the install path is relative to
prefix/DESTDIR where prefix is automatically set to $HOME.

This can produce unexpected results. For example:

make -C tools/perf DESTDIR=/home/jkacur/tmp install-man

creates the directory: /home/jkacur/home/jkacur/tmp/share/...
instead of the expected: /home/jkacur/tmp/share/...

No, not really. Well, logical for people quickly prototyping code
on their own machines, but perf has grown beyond that.

However, I don't like my quick fix either, maybe I can come-up
with something cleaner.

I've applied it meanwhile though, as /home/jkacur/home/jkacur/ is clearly a
misbehavior :-)

sched: Cleanup: remove unused variable in try_to_wake_up()

We haven't used the "orig_rq" variable since
055a00865d "Fix/add missing update_rq_clock() calls"

sched: Implement group scheduler statistics in one struct

Put all statistic fields of sched_entity in one struct, sched_statistics,
and embed it into sched_entity.

This change allows to memset the sched_statistics to 0 when needed (for
instance when forking), avoiding bugs of non initialized fields.
