The patch-set was divided from following thread's patch-set.

The last version of this patchset:

As we're now at -rc7 I'd prefer to take a look at all of this after the
3.7 release - please resend everything shortly after 3.8-rc1.

Almost patches about memory hotplug has been merged into your and Rafael's
tree. And these patches are waiting to open the v3.8 merge window.
Remaining patches are only this patch-set. So we hope that this patch-set
is merged into v3.8.

In merging this patch-set into v3.8, Linux on x86_64 makes a memory hot plug
possible.

Thanks,

If you want to know the reason, please read following thread.

https://lkml.org/lkml/2012/10/2/83

Please include the rationale within each version of the patchset rather
than by linking to an old email. Because

a) this way, more people are likely to read it

b) it permits the text to be maimtained as the code evolves

c) it permits the text to be included in the mainlnie commit, where
people can find it.

The patch-set has only the function of kernel core side for physical
memory hot remove. So if you use the patch, please apply following
patches.

- bug fix for memory hot remove
https://lkml.org/lkml/2012/10/31/269

- acpi framework
https://lkml.org/lkml/2012/10/26/175

What's happening with the acpi framework? has it received any feedback
from the ACPI developers?
