[Xen-devel] [PATCH] linux: secondary CPU handling adjustments

["Jan Beulich" <jbeulich@xxxxxxxxxx>]

Add proper attributes and remove a few unused items.

As usual, written and tested on 2.6.24-rc4 and made apply to the 2.6.18
tree without further testing.

Signed-off-by: Jan Beulich <jbeulich@xxxxxxxxxx>
