Just found it for myself. The answer to the location of the
pagetable is indicated by the swapper_pg_dir variable.
The pagetable starts at swapper_pg_dir, and it is constructed before
the paging is enabled, (in paging_init())
void __init paging_init(void)
{
pagetable_init();
load_cr3(swapper_pg_dir);
__flush_tlb_all();
kmap_init();
}
Thanks.
