The core device API performs extra housekeeping bits that are missing from directly calling cpu_up/down. See commit a6717c01ddc2 ("powerpc/rtas: use device model APIs and serialization during LPM") for an example description of what might go wrong. This also prepares to make cpu_up/down a private interface for anything but the cpu subsystem. Acked-by: Helge Deller <deller@gmx.de> Signed-off-by: Qais Yousef <qais.yousef@arm.com> CC: "James E.J.
