* sysdeps/generic/dl-sysdep.c (_dl_important_hwcaps): If CNT == 1,
allocate space even for the trailing '/'. Reported by John Reiser <jreiser@BitWagon.com>. * sysdeps/unix/sysv/linux/ia64/sysdep.h (LOAD_ARGS_6, ASM_ARGS_6, ASM_CLOBBERS_6): Define. (ASM_CLOBBERS_5): Use ASM_CLOBBERS_6. * sysdeps/unix/sysv/linux/ia64/clone2.S (__clone2): Reorder arguments to match IA-32 order. * sysdeps/unix/sysv/linux/i386/clone.S: Fix comment.
