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.
