Richard Henderson ebcd2cd199 * sysdeps/unix/alpha/sysdep.h (INLINE_SYSCALL1): Use __builtin_expect.
* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_ST_INO_64_BIT)
        Unset for alpha.
        (__ASSUME_TIMEVAL64): Set for alpha.
        * sysdeps/unix/sysv/linux/alpha/Makefile (sysdep_routines): Remove
        adjtimex, osf_sigprocmask, old_adjtimex.
        * sysdeps/unix/sysv/linux/alpha/adjtime.c: Use INLINE_SYSCALL,
        __ASSUME_TIMEVAL64.  Reorg tv64 functions to avoid uninit variable.
        * sysdeps/unix/sysv/linux/alpha/getitimer.S: Use __ASSUME_TIMEVAL64.
        * sysdeps/unix/sysv/linux/alpha/getrusage.S: Likewise.
        * sysdeps/unix/sysv/linux/alpha/gettimeofday.S: Likewise.
        * sysdeps/unix/sysv/linux/alpha/select.S: Likewise.
        * sysdeps/unix/sysv/linux/alpha/setitimer.S: Likewise.
        * sysdeps/unix/sysv/linux/alpha/settimeofday.S: Likewise.
        * sysdeps/unix/sysv/linux/alpha/utimes.S: Likewise.
        * sysdeps/unix/sysv/linux/alpha/wait4.S: Likewise.
        * sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S: Streamline
        PIC code sequence.
        * sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S: Likewise.
        * sysdeps/unix/sysv/linux/alpha/sigaction.c: New file.
        * sysdeps/unix/sysv/linux/alpha/sigprocmask.c: Use INLINE_SYSCALL.
        * sysdeps/unix/sysv/linux/alpha/ustat.c: Likewise.
        * sysdeps/unix/sysv/linux/alpha/xmknod.c: Likewise.
        * sysdeps/unix/sysv/linux/alpha/syscalls.list: Remove osf_sigprocmask,
        sys_ustat, sys_mknod, adjtimex, old_adjtimex.
        * sysdeps/unix/sysv/linux/alpha/sysdep.h (INLINE_SYSCALL): Don't
        defer to __syscall_name; error for rt_sigaction.
        * sysdeps/unix/sysv/linux/alpha/xstatconv.c: Include kernel_stat.h.
