Subject: [PATCH v5 0/3] init: add support to directly boot to a mapped device

This is a resurrection of a patch series from a few years back, first
brought to the dm maintainers in 2010. It creates a way to define dm
devices on the kernel command line for systems that do not use an
initramfs, or otherwise need a dm running before init starts.

This has been used by Chrome OS for several years, and now by Brillo
(and likely Android soon).

The last version was v4:
