Based on patch of Andrew Pinski.
This patch introduces is_a32_compat_task and is_a32_thread so it is
easier to say this is a a32 specific thread or a generic compat thread/task.
Corresponding functions are located in to avoid mess in
headers.

All new 32-bit architectures should have 64-bit off_t type, but existing

To handle it, new config option is added to arch/Kconfig that defaults
ARCH_32BIT_OFF_T to be disabled for non-64 bit architectures. All existing
32-bit architectures enable it explicitly here.
This patch moves required calls to generic files to let other arches use
it if needed. Here also, additional code is introduced, as s390 uses asm
syscall tables, while in general case, wrappers may be used in C code.

ILP32 tasks are needed to be distinguished from lp64 and aarch32.
This patch adds helper functions is_ilp32_compat_{task,thread} and

for following patches in ilp32 patchset.

The kernel needs to be compiled as a LP64 binary for ARM64, even when
using a compiler that defaults to code-generation for the ILP32 ABI.
Consequently, we need to explicitly pass '-mabi=lp64' (supported on
gcc-4.9 and newer).
