Pull perf changes from Ingo Molnar:
"Lots of changes:
- (much) improved assembly annotation support in perf report, with
jump visualization, searching, navigation, visual output
improvements and more.
- kernel support for AMD IBS PMU hardware features. Notably 'perf
record -e cycles:p' and 'perf top -e cycles:p' should work without
skid now, like PEBS does on the Intel side, because it takes
advantage of IBS transparently.
- the libtracevents library: it is the first step towards unifying
tracing tooling and perf, and it also gives a tracing library for
external tools like powertop to rely on.
- infrastructure: various improvements and refactoring of the UI
modules and related code
- infrastructure: cleanup and simplification of the profiling
targets code (--uid, --pid, --tid, --cpu, --all-cpus, etc.)
- tons of robustness fixes all around
- various ftrace updates: speedups, cleanups, robustness
improvements.
- typing 'make' in tools/ will now give you a menu of projects to
build and a short help text to explain what each does.
- ... and lots of other changes I forgot to list.
The perf record make bzImage + perf report regression you reported
should be fixed."

At present reserving the IRLs in the IRQ bitmap in addition to the
dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being
allocated for the x3proto board.
The only reason to permit reservations was to lock down possible hardware
vectors prior to dynamic IRQ scanning, but this doesn't matter much given
that the hardware controller configuration is sorted before we get around
to doing any dynamic IRQ allocation anyways. Beyond that, all of the
tables are __init annotated, so quite a bit more work would need to be
done to support reconfiguring things like IRL controllers on the fly,
much more than would ever make it worth the hassle.

Complete the move of sh64 to it, trim the crap from prototypes,
tidy up a bit. Infrastructure in do_signal() had already been
there, in signal_64 as well as in signal_32 (where it was already
used).

Sigh, I missed to check which architecture Kconfig files actually
include the core Kconfig file. There are a few which did not. So we
broke them.
Instead of adding the includes to those, we are better off to move the
include to init/Kconfig like we did already with irqs and others.
This does not change anything for the architectures using the old
style periodic timer mode. It just solves the build wreckage there.
For those architectures which use the clock events infrastructure it
moves the include of the core Kconfig file to "General setup" which is
a way more logical place than having it at random locations specified
by the architecture specific Kconfigs.

Both of these boards are still using the PIO API sans PCI, and will need
to be carefully converted. As conversion is out of scope for this merge
window, simply make sure NO_IOPORT doesn't get accidentally set for
these, joining a long list of other crap platforms.

Everything is using sparseirq these days, so we have no need to
arbitrarily size nr_irqs ahead of time. The legacy IRQ pre-allocation
likewise has no meaning for us, so that's killed off too. We now depend
on nr_irqs expansion by the generic hardirq layer instead.
It's also worth noting that the majority of boards had completely bogus
values for their nr_irqs relative to their CPU and configurations, so
this ends up correcting behaviour for quite a few platforms.

Attempt to "tidy" up some of the multi IRQ handling and base + IRQ
management. This should keep it limping along without too much hassle,
and no new parts should ever be enabling or using this API anyways.
It doesn't get any closer to lipstick on a pig as this.

We don't support the ISA DMA API, so this is only ever misused. The
dma-sh case inadvertently broke the dreamcast case by testing the wrong
variable for the total number of channels, so this fixes that up too.

This has turned in to quite a mess, and with CPUs that care using
dmaengine now it's about time to start cleaning up after the legacy DMA
code. For starters, kill off the stubs for the CPUs that don't do
anything, as well as all of the unused definitions. This leaves us with a
set of IRQs and base addresses we can deal with later.

Merge reason: We are going to queue up a dependent patch:
"perf tools: Move parse event automated tests to separated object"
That depends on:
commit e7c72d8
perf tools: Add 'G' and 'H' modifiers to event parsing
Conflicts:
tools/perf/builtin-stat.c
Conflicted with the recent 'perf_target' patches when checking the
result of perf_evsel open routines to see if a retry is needed to cope
with older kernels where the exclude guest/host perf_event_attr bits
were not used.

This reverts commit 20e7c297efeca0861adcca073a0d283da659834b.
With store queues enabled the area above P4SEG has special properties
from the MMU's point of view, which was causing fixmap failure. We'll
have to do something else to satisfy the vmalloc range check.
