This is what I'd like to do for POWER9 doorbells, which reworks
the existing code a bit. I guess it won't work on DD1 with OPAL
until darn is fixed (only tested on POWER9 using mambo).
Nicholas Piggin (5):
powerpc/pseries: do not use msgsndp doorbells on POWER9 guests
powerpc: change the doorbell IPI calling convention
powerpc: Introduce msgsnd/doorbell barrier primitives
powerpc/64s: avoid branch for ppc_msgsnd
powerpc/powernv: POWER9 support for msgsnd/doorbell IPI
