perf tools: Add missing headers, mostly stdlib.h

2019-07-09T13:13:22+00:00

Part of the erosion of util/util.h, that will lose its include stdlib.h,
we need to add it to places where it is needed but was getting it
indirectly.

perf annotate: Add csky support

support for the csky CPU architecture.

perf tools: Use linux/ctype.h in more places

2019-06-26T00:13:51+00:00

There were a few places where we still were using the libc version of
ctype.h, switch to the one in tools/lib/ctype.c that the rest of perf
uses.

tools perf: Move from sane_ctype.h obtained from git to the Linux's original

2019-06-26T00:02:47+00:00

We got the sane_ctype.h headers from git and kept using it so far, but
since that code originally came from the kernel sources to the git
sources, perhaps its better to just use the one in the kernel, so that
we can leverage tools/perf/check_headers.sh to be notified when our copy
gets out of sync, i.e. when fixes or goodies are added to the code we've
copied.

This will help with things like tools/lib/string.c where we want to have
more things in common with the kernel, such as strim(), skip_spaces(),
etc so as to go on removing the things that we have in tools/perf/util/
and instead using the code in the kernel, indirectly and removing things
like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements
are made to the original code.

Hopefully this also should help with reducing the difference of code
hosted in tools/ to the one in the kernel proper.

tools x86 machine: Add missing util.h to pick up 'page_size'

2019-06-25T21:01:47+00:00

We're getting it by sheer luck, add that util.h to get the 'page_size'
definition.
