File glibc-2.15-clock_gettime.patch of Package glibc

2011-11-15  Andreas Schwab  <schwab@redhat.com>

* sysdeps/unix/sysv/linux/clock_gettime.c (SYSDEP_GETTIME_CPU)
        [__ASSUME_POSIX_CPU_TIMERS > 0]: Assign to retval and break.
        * sysdeps/unix/sysv/linux/x86_64/clock_gettime.c
        (SYSCALL_GETTIME): Set errno on error.

2011-11-12  Ulrich Drepper  <drepper@gmail.com>

* sysdeps/unix/clock_gettime.c (clock_gettime): No need to assign
        result of SYSDEP_GETTIME_CPU to retval.
        * sysdeps/unix/sysv/linux/clock_gettime.c (SYSDEP_GETTIME_CPU): Add
        parameter list to macro.  Remove trailing semicolon.  Adjust users.
