Linus Torvalds 4d6d367232 - Remoteproc Recovery - by Fernando Guzman Lugo - when a remote processor
crash is detected, this mechanism will remove all virtio children
   devices, wait until their drivers let go, hard reset the remote
   processor and reload the firmware (resulting in the relevant virtio
   children devices re-added). Essentially the entire software stack
   is reset, together with the relevant hardware, so users don't have
   to reset the entire phone.
 - STE Modem driver is added - by Sjur Brændeland
 - OMAP DSP boot address support is added - by Juan Gutierrez
 - A handful of fixes/cleanups - Sjur Brændeland, Dan Carpenter, Emil Goode
