Aside of a Kconfig knob add the following items:
- Two flag bits for the rseq user space ABI, which allow user space to
query the availability and enablement without a syscall.
- A new member to the user space ABI struct rseq, which is going to be
used to communicate request and grant between kernel and user space.
- A rseq state struct to hold the kernel state of this
- Documentation of the new mechanism
