Use ifuncs for time and gettimeofday on x86-64
2011-08-21 Ulrich Drepper <drepper@gmail.com>
* sysdeps/unix/sysv/linux/x86_64/gettimeofday.S: Removed.
* sysdeps/unix/sysv/linux/x86_64/time.S: Removed.
* sysdeps/unix/sysv/linux/x86_64/gettimeofday.c: New file.
* sysdeps/unix/sysv/linux/x86_64/time.c: New file.
* sysdeps/unix/sysv/linux/x86_64/bits/libc-vdso.h: Remove declaration
of __vdso_gettimeofday.
* sysdeps/unix/sysv/linux/x86_64/init-first.c: Remove definition of
__vdso_gettimeofday and __vdso_time. Define __vdso_getcpu with
attribute_hidden.
(_libc_vdso_platform_setup): Remove initialization of
__vdso_gettimeofday and __vdso_time.
