[PATCH] m68knommu: generate asm-offsets for thread_info struct
Offsets into the thread_info structure should be auto generated,
instead of using hard coded offset values. This adds entries to
the asm-offsets generated for the m68knommu varients.
Original patch submitted by Philippe De Muyter <[EMAIL PROTECTED]>
