----------------------------------------------------------------
arch: add pidfd and io_uring syscalls everywhere
This comes a bit late, but should be in 5.1 anyway: we want the newly
added system calls to be synchronized across all architectures in
the release.
I hope that in the future, any newly added system calls can be added
to all architectures at the same time, and tested there while they
are in linux-next, avoiding dependencies between the architecture
maintainer trees and the tree that contains the new system call.

arch: add pidfd and io_uring syscalls everywhere
Add the io_uring and pidfd_send_signal system calls to all architectures.
These system calls are designed to handle both native and compat tasks,
so all entries are the same across architectures, only arm-compat and
the generic tale still use an old format.
