Hi folks,
This small series exposes the PSCI SYSTEM_RESET2 call to guests, which
allows the propagation of a "reset_type" and a "cookie" back to the VMM.
Although Linux guests only ever pass 0 for the type ("SYSTEM_WARM_RESET"),
the vendor-defined range can be used by a bootloader to provide additional
information about the reset, such as an error code.
Cheers,
Will
