+Subject: [PATCH] Fix perf build against newer glibc
+
+Upstream glibc commit 295e904 added a definition for __attribute_const__ to
+cdefs.h.  This causes the following error when building perf:
+
+util/include/linux/compiler.h:8:0: error: "__attribute_const__" redefined [-Werror]
+/usr/include/sys/cdefs.h:226:0: note: this is the location of the previous definition
+
+Wrap __attribute_const__ in #ifndef as we do for __always_inline.
