Is the first of 10 patches. 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 <[email protected]>
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.
