2013-03-01 Roland McGrath <roland@hack.frob.com>
* elf/dl-hwcaps.c (_dl_important_hwcaps):
Change [NEED_DL_SYSINFO || NEED_DL_SYSINFO_DSO] conditionals
to just [NEED_DL_SYSINFO_DSO].
* elf/dl-support.c: Likewise.
* elf/dl-sysdep.c (_dl_sysdep_start): Likewise.
* elf/rtld.c (dl_main): Likewise.
* elf/setup-vdso.h (setup_vdso): Likewise.
* sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Likewise.
* sysdeps/unix/sysv/linux/dl-sysdep.c
(_dl_discover_osversion): Likewise.
2013-03-01 Carlos O'Donell <carlos@redhat.com>
* csu/libc-start.c (__pthread_initialize_minimal): Revert last change.
