#     powerpc/xive: Do not skip CPU-less nodes when creating the IPIs
#     
#     On PowerVM, CPU-less nodes can be populated with hot-plugged CPUs at
#     runtime. Today, the IPI is not created for such nodes, and hot-plugged
#     CPUs use a bogus IPI, which leads to soft lockups.
#     
#     We can not directly allocate and request the IPI on demand because
#     bringup_up() is called under the IRQ sparse lock. The alternative is
#     to allocate the IPIs for all possible nodes at startup and to request
#     the mapping on demand when the first CPU of a node is brought up.
#     
#     Fixes: 7dcc37b3eff9 ("powerpc/xive: Map one IPI interrupt per node")
