* 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.
	(SYSDEP_GETTIME): Use both.
	[! __ASSUME_POSIX_TIMERS] (maybe_syscall_gettime): New function, broken
	out of ...
	(SYSDEP_GETTIME): ... here.  Use it.
	[__NR_clock_gettime] (HANDLED_CPUTIME): Define it.
	(SYSDEP_GETTIME_CPUTIME): New macro.  Handle CPU timers by trying
	kernel support and falling back to hp-timing code.
	* sysdeps/posix/clock_getres.c
	[HP_TIMING_AVAIL] (hp_timing_getres): New function, broken out of ...
	(clock_getres) [HP_TIMING_AVAIL]: ... here.  Call it.

	(SYSDEP_GETRES): ... here.  Use it.
	[__NR_clock_getres] (HANDLED_CPUTIME): Define it.
	(SYSDEP_GETRES_CPUTIME): New macro.  Handle CPU timers by trying
	kernel support and falling back to hp-timing code.
	* sysdeps/unix/sysv/linux/clock_nanosleep.c: Handle
	CLOCK_PROCESS_CPUTIME_ID and CLOCK_PROCESS_THREAD_ID specially,
	translating to the kernel clockid_t for our own process/thread clock.
