powerpc/smp: Support more IPI messages
This patch increases the number of demuxed messages for a controller with a single ipi to 8 for 64-bit systems. This is required because we want to use the IPI mechanism to send messages from a CPU running in KVM real mode in a guest to a CPU in the host to take some action. Currently, we only support 4 messages and all 4 are already taken. Define a fifth message PPC_MSG_RM_HOST_ACTION for this purpose. Signed-off-by:Suresh Warrier <warrier@linux.vnet.ibm.com> Acked-by:
