No, it's this piece of code in x86_32.S (which I've pasted from latest 
xen-unstable, but I think is identical to the code in 2.0.6):

         /* Initialize low and high mappings of all memory with 4MB 
pages */
         mov     $idle_pg_table-__PAGE_OFFSET,%edi
         mov     $0xe3,%eax                  /* PRESENT+RW+A+D+4MB */
1:      mov     %eax,__PAGE_OFFSET>>20(%edi) /* high mapping */
         stosl                                /* low mapping */
         add     $(1<<L2_PAGETABLE_SHIFT),%eax
         cmp     $DIRECTMAP_PHYS_END+0xe3,%eax
         jne     1b
1:      stosl   /* low mappings cover as much physmem as possible */
         add     $(1<<L2_PAGETABLE_SHIFT),%eax
         cmp     $__HYPERVISOR_VIRT_START+0xe3,%eax
         jne     1b
