Auto merge of #2114 - voidc:syscalls, r=JohnTitor
Add more syscall constansts for Linux In #1897 (comment), there was interest in adding constants for recently added Linux syscalls. I went ahead and added consts for syscalls up until (the currently unreleased) Linux 5.12. Here is an overview: | Syscall | NR | since | | ----------------- | --- | ----- | | pidfd_send_signal | 424 | 5.1 | | io_uring_setup | 425 | 5.1 | | io_uring_enter | 426 | 5.1 | | io_uring_register | 427 | 5.1 | | open_tree | 428 | 5.2 | | move_mount | 429 | 5.2 | | fsopen | 430 | 5.2 | | fsconfig | 431 | 5.2 | | fsmount | 432 | 5.2 | | fspick | 433 | 5.2 | | pidfd_open | 434 | 5.3 | | clone3 | 435 | 5.3 | | close_range | 436 | 5.9 | | openat2 | 437 | 5.9 | | pidfd_getfd | 438 | 5.9 | | faccessat2 | 439 | 5.9 | | process_madvise | 440 | 5.10 | | epoll_pwait2 | 441 | 5.11 | | mount_setattr | 442 | 5.12 | ([source](https://github.com/torvalds/linux/blob/1e28eed17697bcf343c6743f0028cc3b5dd88bf0/include/uapi/asm-generic/unistd.h#L825-L865)) The constants are added for `-gnu` and `-musl` targets. I'm unsure to what extend they are actually present in the headers of these libraries. Support is added for all architectures except hexagon.
