They were built ontop of Kames 6 patches sent out within the last few days ([RFC][PATCH] fix ioresouce handling take2 [1/5] was the first). Kames patches fix several real isses and with the 6th patch they are complete from my point of view. I have worked to integrate the feedback I recived on the last round of patches and welcome more ideas/advice. Thanks to everyone who has provied input on these patches already. This patch set allow SPARSEMEM and RESERVE based hot-add to work. I have test both options and they work as expected. I am adding memory to the 2nd node of a numa system (x86_64). Major changes from last set is the config change and RESERVE enablment. From: Keith Mannthey Make ACPI motherboard driver not attach to devices/handles it dosen't expect. Fix a bug where the motherboard driver attached to hot-add memory event and caused the add memory call to fail.
