aarch64 support

[sktzwhj]

Hi,

It seems the current code does not support aarch64 arch, at least the system call numbers are different. Am I understand it correctly? Are there any existing alternatives?

Thanks.

RIKEN has an AArch64 port (https://github.com/RIKEN-SysSoft/syscall_intercept/tree/master/arch/aarch64). However, it has not been upstreamed to the main repo (this repo).

I think an AArch64 port is very useful, considering the increasing importance of AArch64 in HPC systems. Various user space file systems for HPC systems are developed using this library.
