include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO. fs/binfmt_elf.c has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT entries. So in the worst case, saved_auxv does not get an AT_NULL entry at the end. The saved_auxv array must be terminated with an AT_NULL entry. Make the size of mm_struct->saved_auxv arch dependend, based on the number of ARCH_DLINFO entries.
