Pull core entry/ptrace update from Thomas Gleixner:
"Provide a ptrace set/get interface for syscall user dispatch. The main
purpose is to enable checkpoint/restore (CRIU) to handle processes
which utilize syscall user dispatch correctly"

selftest, ptrace: Add selftest for syscall user dispatch config api
ptrace: Provide set/get interface for syscall user dispatch
syscall_user_dispatch: Untag selector address before access_ok()
syscall_user_dispatch: Split up set_syscall_user_dispatch()
