* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_PSELECT,cvs/fedora-glibc-20070814T0725cvs/fedora-glibc-20070814T0643
__ASSUME_PPOLL, __ASSUME_ATFCTS, __ASSUME_SET_ROBUST_LIST,
__ASSUME_UTIMENSAT, __ASSUME_FALLOCATE): Update per-arch conditions
when each feature was introduced.
* sysdeps/unix/sysv/linux/dl-vdso.c: Don't include dl-hash.h.
* sysdeps/unix/sysv/linux/dl-vdso.h: Don't include dl-hash.h if NDEBUG.
(CHECK_HASH): New macro.
(PREPARE_VERSION): Use it.
* sysdeps/unix/sysv/linux/pselect.c (__generic_pselect): Only provide
prototype if not __ASSUME_PSELECT.
* sysdeps/unix/sysv/linux/ppoll.c (__generic_ppoll): Only provide
prototype if not __ASSUME_PPOLL.
* sysdeps/unix/sysv/linux/dl-osinfo.h (ROUND): #undef after use.
* sysdeps/unix/clock_settime.c (freq, __pthread_clock_settime,
hp_timing_settime): Don't define or declare if HANDLED_CPUTIME
is defined.
