commit 12c5bc346326449b0bd7d9e3a751884d4117eed3
Author: Samuel Thibault <address@hidden>
Date:   Sat Mar 5 23:00:38 2011 +0100

    Fix temporary direct mapping during page table enabling
    
    * i386/i386at/model_dep.c (i386at_init): Count the number of actually
    needed temporary L1 direct mapping by getting the last used address from
    init_alloc_aligned(), instead of hardcoding it to 1 or 3, and then use a for
    loop.

commit 048c28bf88792efc3b75d940110b6ae565847f43
Author: Samuel Thibault <address@hidden>
Date:   Thu Mar 3 04:14:51 2011 +0100

    Keep supplementary L1 pages read-only
    
    * i386/intel/pmap.c (pmap_bootstrap): Fix loop which keeps supplementary L1
    pages read-only: break as soon as one of the L1 supplementary pages has been
    recognized, so that its pte does not get rewritten read-write.
