Attilio Rao e946b94934 On all the architectures, avoid to preallocate the physical memory ... for nodes used in vm_radix. On architectures supporting direct mapping, also avoid to pre-allocate the KVA for such nodes. In order to do so make the operations derived from vm_radix_insert() to fail and handle all the deriving failure of those. vm_radix-wise introduce a new function called vm_radix_replace(), which can replace a leaf node, already present, with a new one, and take into account the possibility, during vm_radix_insert() allocation, that the operations on the radix trie can recurse. This means that if operations in vm_radix_insert() recursed vm_radix_insert() will start from scratch again.
