* rt/tst-cpuclock2.c: New file. * rt/tst-cputimer1.c: New file. * rt/tst-cputimer2.c: New file. * rt/tst-cputimer3.c: New file. * rt/Makefile (tests): Add them. * sysdeps/unix/sysv/linux/kernel-posix-cpu-timers.h: New file. * sysdeps/unix/sysv/linux/clock_getcpuclockid.c: New file. * sysdeps/unix/sysv/linux/ia64/clock_getcpuclockid.c (HAS_CPUCLOCK): New macro. (clock_getcpuclockid): Function removed. #include the new linux file to define it instead. * sysdeps/unix/clock_gettime.c [HP_TIMING_AVAIL] (hp_timing_gettime): New function, broken out of ... (clock_gettime) [HP_TIMING_AVAIL]: ... here. Call it. (realtime_gettime): New function, broken out of ... (clock_gettime) [! HANDLED_REALTIME]: ... here. Call it. (clock_gettime) [SYSDEP_GETTIME_CPU]: Use new macro in default case. * sysdeps/unix/sysv/linux/clock_gettime.c (SYSCALL_GETTIME): New macro. (SYSDEP_GETTIME_CPUTIME): New macro.
