As of yesterday I finished fixing all OpenSSI related compiler warnings and
errors.

There are some changes in the core that required rework in OpenSSI.  One of
them is the ldt element in mm_context_t structure.  The element used to
point to a contiguous memory region and is now an array of highmem page
pointers.  It affects the data marshaling code in architecture dependent XDR
interface for process migration.  I've only updated the i386 portion.

We still need to add KDB and I haven't tried the kernel yet.  When it works
we'll gain all the drivers and fixes that comes with CentOS 4.8 that aren't
in the vanilla 2.6.11 kernel.
