Merge change Ia0a40883 into eclair
* changes:
Modify the binder to request 1M - 2 pages instead of 1M. The backing store in the kernel requires a guard page, so 1M allocations fragment memory very badly. Subtracting a couple of pages so that they fit in a power of two allows the kernel to make more efficient use of its virtual address space.
