Hi, Here are a couple of small fixes to support CPU hot unplug. There are still some issues to be investigated as, in some occasions, after a couple of plug and unplug, the cpu which was removed receives a 'lost' interrupt. This showed to be the decrementer under QEMU.
Nevertheless, these patches are required and provide a significant improvement to support CPU removal. Tested under a phyp and a XIVE QEMU model for pseries. Thanks, C.
