* sysdeps/unix/sysv/linux/powerpc/powerpc32/kernel_stat.h: Sync

with Linux kernel. 
* sysdeps/unix/sysv/linux/sparc/sparc32/kernel_stat.h: Likewise. 
* sysdeps/unix/sysv/linux/s390/s390-64/kernel_stat.h: Likewise. 
* sysdeps/unix/sysv/linux/hppa/kernel_stat.h: Likewise.
	* sysdeps/unix/sysv/linux/kernel_stat.h
	(_HAVE_STAT_NSEC,_HAVE_STAT_NSEC64): New.

	* sysdeps/unix/sysv/linux/xstatconv.c (xstat_conv): Readd
	__unused[1-3] since they're needed by some platforms.  Handle
	_HAVE_STAT_NSEC and _HAVE_STAT_NSEC64.

	* sysdeps/unix/sysv/linux/x86_64/bits/stat.h: Add nsec resolution
	for structs stat and stat64.
	* sysdeps/unix/sysv/linux/ia64/bits/stat.h: Likewise.
