The only difference is that non-compat version forces O_LARGEFILE,
and it should be the default behaviour for all architectures, as
we don't support 32-bit off_t. The only exception is tile32, that
continues with compat version of syscalls.

If nothing will come here on review, I'll send v8 at the beginning of
the next week. Is this plan OK?
And this is the backport on the v4.11 kernel:

The only difference is that non-compat version forces O_LARGEFILE,
and it should be the default behaviour for all architectures, as
we are going to drop the support of 32-bit userspace off_t.
The exception is tile32 that continues with compat version of syscalls.

a libc may use 32-bit off_t, and therefore want to limit the file size
to 4GB unless specified differently in the open flags.

As we support more than one compat formats, it looks more reasonable
to not use fs/compat_binfmt.c. Custom binfmt_elf32.c allows to move aarch32
specific definitions there and make code more maintainable and readable.

ILP32 uses AARCH32 compat structures and syscall handlers for signals.
But ILP32 struct rt_sigframe and ucontext differs from both LP64 and
AARCH32. So some specific mechanism is needed to take care of it.

According to userspace/kernel ABI, userspace off_t is passed in register pair
