Documentation/kbuild/makefiles.txt says the change for align options
occurred at GCC 3.0, and Documentation/process/changes.rst says the
minimal supported GCC version is 3.2, so it should be safe to hard-code
-falign* options.

As the Sphinx build seems very fragile, specially for
PDF output, add a notice about how to use it on a virtual

This series enables aarch64 with ilp32 mode.
As supporting work, it introduces ARCH_32BIT_OFF_T configuration
option that is enabled for existing 32-bit architectures but disabled
for new arches (so 64-bit off_t userspace type is used by new userspace).
Also it deprecates getrlimit and setrlimit s
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.

All new 32-bit architectures should have 64-bit userspace 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 explici
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

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).

Based on patch of Andrew Pinski.
This patch introduces is_a32_compat_task and is_a32_thread so it is

ILP32 uses AARCH32 compat structures and syscall handlers for signals.
But ILP32 struct rt_sigframe and ucontext differs from both LP64 and
