+ILP32 AARCH64 SYSCALL ABI
+=========================
+
+This document describes the ILP32 syscall ABI and where it differs
+from the generic compat linux syscall interface.
+
+Syscalls which normally would pass 64bit values as two arguments;
+now pass the 64bit value as one argument.
+
+struct rt_sigframe is redefined and contains struct compat_siginfo,
+as compat syscalls expects, and struct sigframe, taken from lp64 to
+handle AARCH64 register set.
+
+Syscalls openat and open_by_handle_at are as non-compat as, it's
+temporary solution. There is expected global refactoring for all
+platforms.
