LANDED
From: Oliver O'Halloran <oohall@gmail.com>

Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
Status: Landed in mainline as 2d9b332d99b2 on 2020-01-23.
On PowerNV a few different kinds of reboot are supported. We'd like to be
able to exercise these from xmon so allow 'zr' to take an argument, and
pass that to the ppc_md.restart() function.
