X-Git-Tag: omap-for-v4.1/fixes-rc1~156^2~66^2~43
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=39f5704399042fff5f0d5f6af32bbbc3e787a897;p=pandora-kernel.git

perf tools: Define _GNU_SOURCE on pthread_attr_setaffinity_np feature check

The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE
must be defined before pthread.h is included in order to get the proper
function declaration.  Define this in the Makefile.

Without this defined, the feature check fails on a Fedora system with
gcc5 and then the perf build later fails with conflicting prototypes for
the function.
