[Qemu-devel] [PATCH v2 2/8] spapr: move the IRQ server number mapping under the machine

[Cédric Le Goater]

This is the second step to abstract the IRQ 'server' number of the
XICS layer. Now that the prereq cleanups have been done in the
previous patch, we can move down the 'cpu_dt_id' to 'cpu_index'
mapping in the sPAPR machine handler.
