The same problem potentially exists in the alpha if the kernel VM space overflows grows such that a new level 2 page table is needed (as you know, the alpha uses 3 levels of page tables and if a level 3 page table is added, nothing special needs to happen since the corresponding level 2 page table is already shared by all processes). The suggested fix looks as if it could be easily adapted to the alpha pmap. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
