Hide internal sysinfo functions [BZ #18822]
Hide internal sysinfo functions to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * include/sys/sysinfo.h (__get_nprocs_conf): Add libc_hidden_proto. (__get_nprocs): Likewise. (__get_phys_pages): Likewise. (__get_avphys_pages): Likewise. (__get_child_max): Add attribute_hidden. * misc/getsysstats.c (__get_nprocs_conf): Add libc_hidden_def. (__get_nprocs): Likewise. (__get_phys_pages): Likewise. (__get_avphys_pages): Likewise. * sysdeps/mach/getsysstats.c (__get_nprocs_conf): Add libc_hidden_def. (__get_nprocs): Likewise. (__get_phys_pages): Likewise. (__get_avphys_pages): Likewise. * sysdeps/unix/sysv/linux/getsysstats.c (__get_nprocs): Add libc_hidden_def. (__get_nprocs_conf): Likewise. (__get_phys_pages): Likewise.
