Olaf Hering 4f9a58d75b increase AT_VECTOR_SIZE to terminate saved_auxv properly
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.
