[Qemu-devel] [PATCH 02/11] pseries: Cleanup error handling of spapr_cpu_init()

[David Gibson <david@gibson.dropbear.id.au>]

Currently spapr_cpu_init() is hardcoded to handle any errors as fatal.
That works for now, since it's only called from initial setup where an
error here means we really can't proceed.

However, we'll want to handle this more flexibly for cpu hotplug in future
so generalize this using the error reporting infrastructure.  While we're
at it make a small cleanup in a related part of ppc_spapr_init() to use
the error infrastructure instead of an old-style explicit fprintf / exit.
