perf build: Add arch x86 objects building

2015-02-12T16:12:01+00:00

Move the x86 arch objects building under build framework to be included
in the libperf build object.

Adding also arch/$(ARCH)/Build files for the rest of the archs. The
reason for this is that in arch/Build we now do:

  +libperf-y += $(ARCH)/

which would make the build to fail on other architectures, because the
build framework requires 'Build' file in nested directories and this
patch adds it only for x86.

perf kvm: Add stat support on s390

2014-07-16T20:57:33+00:00

On s390, the vmexit event has a tree-like structure: between
exit_event_begin and exit_event_end several other events may happen and
with each of them refining the previous ones.

This patch adds a decoder for such events to the generic code and also
the files  and kvm-stat.c for s390.

Commands 'perf kvm stat record', 'report' and 'live' are supported.

perf tools: Fix build on non-glibc systems due to libio.h absence

2013-03-15T16:05:13+00:00

Including libio.h causes build failures on uClibc systems (which lack
libio.h).

It appears that libio.h was only included to pull in a definition for
NULL, so it has been replaced by stddef.h.

On powerpc, libio.h was conditionally included, but could be removed
completely as it is unneeded. Also, the included of stdlib.h was changed
to stddef.h (as again, only NULL is needed).
