Hello Isaku,
I don't modifying my patch, but I think adding xenheap_megabytes_support
as a boot time option is a different patch from mine. I think we agree
on this?
For the paranthesis, then I don't mind redoing the patch with those in
it, it's not a big deal for me.
Does thos work better?
Cheers,
Jes

For bigger system the default size of XENHEAP is far from
sufficient. This bases the size of XENHEAP on the NODES_SHIFT, leaving
the old default for a NODES_SHIFT <= 5 for those who prefer to compile
a smaller Xen.
