Alan Cox e94965d82e Previously, vm_radix_remove() would panic if the radix trie didn't ... contain a vm_page_t at the specified index. However, with this change, vm_radix_remove() no longer panics. Instead, it returns NULL if there is no vm_page_t at the specified index. Otherwise, it returns the vm_page_t. The motivation for this change is that it simplifies the use of radix tries in the amd64, arm64, and i386 pmap implementations. Instead of performing a lookup before every remove, the pmap can simply perform the remove.
