[PATCH tip/core/rcu 0/8] Automate initrd generation for v4.21/v5.0

[Paul E. McKenney]

Hello!

This series causes rcutorture to automatically generate the required
initrd when needed, instead of giving very obtuse error messages.

1.	Automatically create initrd directory, courtesy of Connor Shu.

2.	Add initrd support for systems lacking dracut.

3.	Make initrd/init execute in userspace.

4.	Add cross-compile capability to initrd.sh.

5.	Always strip using the cross-compiler, courtesy of Willy Tarreau.

6.	Check initrd/init instead of initrd only, courtesy of Willy Tarreau.

7.	Import a copy of nolibc, courtesy of Willy Tarreau.

8.	Make use of nolibc when available, courtesy of Willy Tarreau.

							Thanx, Paul
