Pull m68nommu updates from Greg Ungerer:
"A series of cleanups for the FLAT format binary loader, binfmt_flat,
from Christoph.
The end goal is to support no-MMU on RISC-V, and the last patch
enables that"

binfmt_flat: move the MAX_SHARED_LIBS definition to binfmt_flat.c
binfmt_flat: remove the persistent argument from flat_get_addr_from_rp
binfmt_flat: provide an asm-generic/flat.h
binfmt_flat: make support for old format binaries optional
binfmt_flat: add a ARCH_HAS_BINFMT_FLAT option
binfmt_flat: add endianess annotations
binfmt_flat: use fixed size type for the on-disk format
binfmt_flat: consolidate two version of flat_v2_reloc_t
binfmt_flat: remove the unused OLD_FLAT_FLAG_RAM definition
binfmt_flat: remove the uapi <linux/flat.h> header
