nptl: Assume __ASSUME_FUTEX_CLOCK_REALTIME support
This patch assumes realtime clock support for nptl and thus removes all the associated code. For __pthread_mutex_timedlock the fallback usage for the case where lll_futex_timed_wait_bitset it not set define is also removed. The generic lowlevellock-futex.h always define it, so for NPTL code the check always yield true. Checked on x86_64-linux-gnu and i686-linux-gnu. * nptl/nptl-init.c (__have_futex_clock_realtime, __have_futex_clock_realtime): Remove definition. (__pthread_initialize_minimal_internal): Remove FUTEX_CLOCK_REALTIME check test for !__ASSUME_FUTEX_CLOCK_REALTIME. * nptl/pthread_mutex_timedlock.c (__pthread_mutex_timedlock): Assume __ASSUME_FUTEX_CLOCK_REALTIME support. * sysdeps/unix/sysv/linux/i386/lowlevellock.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/lowlevellock.S: Likewise. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_FUTEX_CLOCK_REALTIME): Remove. * sysdeps/nptl/lowlevellock-futex.h (lll_futex_timed_wait_bitset): Adjust comment.
