Hi Tim,

There are some patches which are required for the ubuntu-hardy tree to
support physical cpu hot-remove. 
In the mainline too there are some deadlock issues when hot removing a
processor. This issues were discussed in detail over here

There are a total of 7 patches which should be applied to the hardy tree
to fix these issues. Of these 2 have been merged in the mainline tree.
(I will send you these 2 patches in a separate mail)

The rest of the 5 patches are in the ACPI tree, and Len had mentioned
that, those patches will be pushed in the 2.6.27 merge window.

The commits are

I am interested in knowing how do we merge these patches in the
ubuntu-hardy tree, can these patches be applied to hardy for the 3rd
July release ?
