Last change on this file since 349 was 349, checked in by alain, 10 years ago
Introducing a new attribute "local" in the mapping_vseg_t structure, to support distributed page tables, kernel code and user code: A "local" vseg is only mapped in the local page table (The local page table is the page table stored in the same cluster as the vseg itself).
