* 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.

(clock_getres) [! HANDLED_REALTIME]: ... here. Call it.
(clock_getres) [SYSDEP_GETRES_CPU]: Use new macro in default case.
* sysdeps/unix/sysv/linux/clock_getres.c (SYSCALL_GETRES): New macro.
(SYSDEP_GETRES_CPUTIME): New macro.
(SYSDEP_GETRES): Use both.
[! __ASSUME_POSIX_TIMERS] (maybe_syscall_getres): New function, broken
out of ...
(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.
