Yes, these values are for 32 bit only syscalls, the syscall epoll_create is not support for 64bit arm64. 

Reference to man 2 epoll_create, we can see that epoll_create/epoll_create1 are supported If only we include the header file sys/epoll.h.

Is it better that we call epoll_create replace to syscall __NR_epoll_create since some plateform not support it?


Thanks for you review!
