2015-09-30	tools: Fix shadowed declaration in err.h	Jiri Olsa
	The error variable breaks build on CentOS 6.7, due to collision with global error symbol: CC util/evlist.o cc1: warnings being treated as errors In file included from util/evlist.c:28: tools/include/linux/err.h: In function ‘ERR_PTR’: tools/include/linux/err.h:34: error: declaration of ‘error’ shadows a global declaration util/util.h:135: error: shadowed declaration is here Using 'error_' name instead to fix it.

2015-09-15	tools: Add err.h with ERR_PTR PTR_ERR interface	Jiri Olsa
	Adding part of the kernel's <linux/err.h> interface: inline void * __must_check ERR_PTR(long error); inline long __must_check PTR_ERR(__force const void ptr); inline bool __must_check IS_ERR(__force const void ptr); It will be used to propagate error through pointers in following patches.
