* sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features):
* On Linux, the clock function now uses the clock_gettime system call
for improved precision, rather than old times system call.
+
+* Added new API functions pthread_getattr_default_np and
+ pthread_setattr_default_np to get and set the default pthread
+ attributes of a process.
