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.
