Hi Thomas, Here's the v2 patchset according to your suggestion. While testing ioapic hotplug, two bugs were found. 1) acpi_ioapic_add() is only called during hotadd of ioapics. Those already present during system boot are not added, and thus cannot be hot-removed. 2) ioapics[i].iomem_res were assigned the wrong pointers, causing panic while hot-removing ioapics. On a 4-socket brickland, hot-removal of the 3 sockets can be done only after applying the first two patches. The 3rd patch is optional. Regards, Rui v2: split the second patch into a one liner and a cleanup patch according to Thomas.
