+Subject: [PATCH 3/3] Add aarch64 support
+
+This is a bit complicated because AArch64, as a completely new architecture,
+does not support the deprecated epoll_create and epoll_wait syscalls.
+Instead, these wrap the epoll_create1 and epoll_pwait syscalls, which serve
+the same purpose but with slightly different syntaxes.
