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.

This series enables aarch64 with ilp32 mode.

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).

ILP32 tasks are needed to be distinguished from lp64 and aarch32.
This patch adds helper functions is_ilp32_compat_{task,thread} and
thread flag TIF_32BIT_AARCH64 to address it. This is a preparation
for following patches in ilp32 patchset.

The newer prlimit64 syscall provides all the functionality provided by
the getrlimit and setrlimit syscalls and adds the pid of target process,
so future architectures won't need to include getrlimit and setrlimit.
Therefore drop getrlimit and setrlimit syscalls from the generic syscall

They may be accessed from low-level code, so isolating is a measure to

never should be)"

As we support more than one compat formats, it looks more reasonable

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

the framework takes care of feeding the watchdog until userspace opens
