[Xen-devel] [PATCH] xen/malloc: handle correctly page allocation when align > size

[Julien Grall <julien.grall@xxxxxxxxxx>]

When align is superior to size, we need to retrieve the order from
align during multiple page allocation. I guess it was the goal of the commit
fb034f42 "xmalloc: make close-to-PAGE_SIZE allocations more efficient".
