perf tools: No need to include internal/lib.h from util/util.h

2019-09-25T12:51:48+00:00

That was done just to have users of writen() and readn(), that before
had their prototypes in util/util.h to get it without having to add an
include for internal/lib.h, but the right way is to add it and by now
all places already do it.

Fix a fallout were readlink() was used but unistd.h was being obtained
by luck thru util.h -> internal/lib.h, now to check why unistd.h is
being included there...

libperf: Move 'page_size' global variable to libperf

2019-09-25T12:51:48+00:00

We need the 'page_size' variable in libperf, so move it there.

Add a libperf_init() as a global libperf init function to obtain this
value via sysconf() at tool start.

Committer notes:

Add internal/lib.h to tools/perf/ files using 'page_size', sometimes
replacing util.h with it if that was the only reason for having util.h
included.

libperf: Adopt the readn()/writen() functions from tools/perf

2019-07-29T21:34:46+00:00

Move the readn()/writen() functions into libperf.

Keep those non-namespaced names because they will be shared only between
perf and libperf.

Again, these are not exported functions.

perf tools: Move get_current_dir_name() cond prototype out of util.h

2019-07-09T13:13:26+00:00

And in a separate header, so that we erode util.h a bit more.

perf namespaces: Move the conditional setns() prototype to namespaces.h

2019-07-09T13:13:26+00:00

Out of util.h, to reduce its scope, and since we have a namespaces.h
header, much better to have it there, where it is related to.

perf kallsyms: Adopt hex2u64 from tools/perf/util/util.h

2019-06-25T21:13:17+00:00

Just removing more stuff from tools/perf/, this is mostly used in the
kallsyms parsing and in places in perf where kallsyms is involved, so we
get it for free there.

With this we reduce a bit more util.h.
