Subject: UBUNTU: [Config] Replace EXT{2,3} with EXT4_USE_FOR_EXT23.

BugLink: https://bugs.launchpad.net/bugs/1513463

The kernel has grown too large to fit on the Mako boot
partition. This config change makes it smaller without
losing any functionality due to making use of EXT4's
backward-compatibility.

Subject: UBUNTU: [Config] Enable squashfs for mako.

BugLink: https://bugs.launchpad.net/bugs/1513207

These config changes were copied from the trusty kernel, though
BCJ filter decoding was only enabled for ARM.

UBUNTU: SAUCE: Add seccomp selftests.

BugLink: http://bugs.launchpad.net/bugs/1509489

Taken from the history of https://github.com/redpig/seccomp. This
has been deprecated in favor of the tests in mainline (which are
based on this repository), but the mainline tests include tests
for the seccomp syscall and tsync, neither of which are included
in this backport.

ARM: 7579/1: arch/allow a scno of -1 to not cause a SIGILL

BugLink: http://bugs.launchpad.net/bugs/1509489

On tracehook-friendly platforms, a system call number of -1 falls
through without running much code or taking much action.

ARM is different. This adds a short-circuit check in the trace path to
avoid any additional work, as suggested by Russell King, to make sure
that ARM behaves the same way as other platforms.

ARM: 7578/1: arch/move secure_computing into trace

BugLink: http://bugs.launchpad.net/bugs/1509489

There is very little difference in the TIF_SECCOMP and TIF_SYSCALL_WORK
path in entry-common.S, so merge TIF_SECCOMP into TIF_SYSCALL_WORK and
move seccomp into the syscall_trace_enter() handler.

Expanded some of the tracehook logic into the callers to make this code
more readable. Since tracehook needs to do register changing, this portion
is best left in its own function instead of copy/pasting into the callers.

Additionally, the return value for secure_computing() is now checked
and a -1 value will result in the system call being skipped.

ARM: 7577/1: arch/add syscall_get_arch

BugLink: http://bugs.launchpad.net/bugs/1509489

Provide an ARM implementation of syscall_get_arch. This is a pre-requisite
for CONFIG_HAVE_ARCH_SECCOMP_FILTER.
