This patch consolidates all the non cancellable nanosleep calls to use the __nanosleep_nocancel identifier. For non cancellable targets it will be just a macro to call the default respective symbol while on Linux will be a internal one. Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu. * nptl/pthread_mutex_timedlock.c (__pthread_mutex_timedlock): Replace nanosleep_not_cancel with __nanosleep_nocancel. * sysdeps/generic/not-cancel.h (nanosleep_not_cancel): Remove macro. (__nanosleep_nocancel): New macro. * sysdeps/unix/sysv/linux/nanosleep.c (__nanosleep_nocancel): New function. * sysdeps/unix/sysv/linux/not-cancel.h (nanosleep_not_cancel): Remove macro. (__nanosleep_nocancel): New prototype.
