Hi all,
Here's a small set of patches for memory hotplug which I needed to get the Xen balloon driver working.
1. add add_memory_resource(), which allow a caller to provide the resource structure for memory being added, 2. add warnings when you try to add non-section-aligned and sized memory since it has undesireable results when you do so, and 3. decrease the i386 PAE section size to 2^29 (=512MB), since 1G is a bit too large for virtual memory ballooning (4. don't steal all memory in paravirt_disable_iospace)
Still unresolved is how to prevent the user from onlining balloon memory via sysfs, since that will almost certainly cause the kernel to crash.
Thanks, J
