nptl: Remove __ASSUME_PRIVATE_FUTEX
Since __ASSUME_PRIVATE_FUTEX is always defined, this patch removes the !__ASSUME_PRIVATE_FUTEX paths. Tested with build-many-glibcs.py. * nptl/allocatestack.c (allocate_stack): Remove the !__ASSUME_PRIVATE_FUTEX paths. * nptl/descr.h (header): Remove the !__ASSUME_PRIVATE_FUTEX path. * nptl/nptl-init.c (__pthread_initialize_minimal_internal): Likewise. * sysdeps/i386/nptl/tcb-offsets.sym (PRIVATE_FUTEX): Removed. * sysdeps/powerpc/nptl/tcb-offsets.sym (PRIVATE_FUTEX): Likewise. * sysdeps/sh/nptl/tcb-offsets.sym (PRIVATE_FUTEX): Likewise. * sysdeps/x86_64/nptl/tcb-offsets.sym (PRIVATE_FUTEX): Likewise. * sysdeps/i386/nptl/tls.h: (tcbhead_t): Remve the !__ASSUME_PRIVATE_FUTEX path. * sysdeps/s390/nptl/tls.h (tcbhead_t): Likewise. * sysdeps/sparc/nptl/tls.h (tcbhead_t): Likewise. * sysdeps/x86_64/nptl/tls.h (tcbhead_t): Likewise. * sysdeps/unix/sysv/linux/i386/lowlevellock.S: Remove the !__ASSUME_PRIVATE_FUTEX macros. * sysdeps/unix/sysv/linux/lowlevellock-futex.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/cancellation.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/lowlevellock.S: Likewise. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_PRIVATE_FUTEX): Removed.
