Don't unconditionally use clock_gettime vsyscall on x86-64
2011-09-06 Ulrich Drepper <drepper@gmail.com>
* sysdeps/unix/sysv/linux/x86_64/clock_gettime.c: New file.
* sysdeps/unix/sysv/linux/clock_gettime.c (SYSCALL_GETTIME): Allow
already be defined. Change to take two parameters and don't assign
result to variable. Adjust all users.
Define INTERNAL_GETTIME if not already defined.
Use INTERNAL_GETTIME instead of INTERNAL_VSYSCALL got clock_gettime
call.
* sysdeps/unix/sysv/linux/x86_64/sysdep.h: Don't define
HAVE_CLOCK_GETTIME_VSYSCALL.
* sysdeps/unix/clock_gettime.c: Adjust use of SYSDEP_GETTIME_CPU.

Make sure __vdso_clock_gettime always contains a valid pointer
2011-09-07 Ulrich Drepper <drepper@gmail.com>
* sysdeps/unix/sysv/linux/x86_64/init-first.c
(_libc_vdso_platform_setup): If vDSO is not present store pointer to
syscall wrapper around clock_gettime in __vdso_clock_gettime.
* sysdeps/unix/sysv/linux/x86_64/syscalls.list: Add entry for
clock_gettime.
