Vlad, I had to add the following fix to the tree in order
to unbreak the build when CONFIG_HIGHMEM is enabled.

highmem: Export totalhigh_pages.

Hash et al. sizing code in SCTP wants to make the
calculation totalram_pages - totalhigh_pages, just
like TCP.  But this requires an export for the
CONFIG_HIGHMEM case to work.
