[PATCH] arm64: Fix the arm64_personality() syscall wrapper redirection

by Catalin Marinas

Following commit 4378a7d4be30 ("arm64: implement syscall wrappers"), the syscall function names gained the '__arm64_' prefix. Ensure that we have the correct #define for redirecting a default syscall through a wrapper.
