Swap upper/lower 32 bits for 64-bit compat syscalls, conditioned on endianness. This is modeled after the same functionality in arch/mips/kernel/linux32.c. This fixes compat_sys on ppc64le, when called by 32-bit little-endian processes. Tested with `file /bin/bash` (pread64) and `truncate -s 5G test` (ftruncate64).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
