* init.c (__pthread_initialize_minimal_internal): Check whether
private futexes are available. * allocatestack.c (allocate_stack): Copy private_futex field from current thread into the new stack. * sysdeps/unix/sysv/linux/x86_64/libc-lowlevellock.S: Use private futexes if they are available. * sysdeps/unix/sysv/linux/i386/i486/libc-lowlevellock.S: Likewise * sysdeps/unix/sysv/linux/x86_64/lowlevellock.S: Adjust so that change in libc-lowlevellock.S allow using private futexes. * sysdeps/unix/sysv/linux/i386/i486/lowlevellock.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/lowlevellock.h: Define FUTEX_PRIVATE_FLAG. * sysdeps/unix/sysv/linux/i386/lowlevellock.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/pthread_once.S: Use private futexes if they are available. * sysdeps/unix/sysv/linux/i386/pthread_once.S: Likewise. * sysdeps/x86_64/tcb-offsets.sym: Add PRIVATE_FUTEX. * sysdeps/i386/tcb-offsets.sym: Likewise. * sysdeps/x86_64/tls.h (tcbhead_t): Add private_futex field. * sysdeps/i386/tls.h (tcbhead_t): Likewise.
