Hi,
Full list of cleanups:
- mm: Remove dependency on CONFIG_FLATMEM from online_page(),
- mm: Enable set_page_section() only if CONFIG_SPARSEMEM
and !CONFIG_SPARSEMEM_VMEMMAP,
- mm: pfn_to_section_nr()/section_nr_to_pfn() is valid
only in CONFIG_SPARSEMEM context,
- mm: Do not define PFN_SECTION_SHIFT if !CONFIG_SPARSEMEM.
Those patches applies to Linus' git tree, v2.6.39-rc5 tag.
They are required by latest memory hotplug support for Xen balloon
driver patch which will be sent soon.
Daniel
