We have tools/build/feature/test-all.c to speed up feature testing,
doing all tests at once, but then all tests in this file should normally
pass.
That is not the case with the sched-getcpu one, that wasn't passing when
included from test-all.c because it needs to have _GNU_SOURCE defined
before including sched.h, but _GNU_SOURCE is defined by a header
included from another feature test included earlier in test-all.d,
test-libpython.c, resulting in:
$ cat /tmp/build/perf/feature/test-all.make.output
In file included from test-all.c:121:0:
test-sched_getcpu.c:1:0: error: "_GNU_SOURCE" redefined [-Werror]
#define _GNU_SOURCE
In file included from /usr/include/python2.7/pyconfig.h:6:0,
from /usr/include/python2.7/Python.h:8,
from test-libpython.c:1,
from test-all.c:13:
/usr/include/python2.7/pyconfig-64.h:1177:0: note: this is the location of the previous definition
#define _GNU_SOURCE 1
cc1: all warnings being treated as errors
Which would trigger testing the tests individually, when that
_GNU_SOURCE redefinition would not take place, and the whole process
would continue, just slower... Fix it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
