Subject: arch_rebalance_pgtables call
From: Martin Schwidefsky <[EMAIL PROTECTED]>
In order to change the layout of the page tables after an mmap has crossed the
adress space limit of the current page table layout a architecture hook in
get_unmapped_area is needed. The arguments are the address of the new mapping
and the length of it.
