Cédric Le Goater cc56939802 powerpc/xive: Clear XIVE internal structures when a CPU is removed ... Commit eac1e731b5 ("powerpc/xive: guest exploitation of the XIVE interrupt controller") introduced support for the XIVE exploitation mode of the P9 interrupt controller on the pseries platform. At that time, support for CPU removal was not complete on PowerVM and CPU hot unplug remained untested. It appears that some cleanups of the XIVE internal structures are required before releasing the CPU, without which the kernel crashes in a RTAS call doing the CPU isolation. These changes fix the crash by deconfiguring the IPI interrupt source and clearing the event queues of the CPU when it is removed.
