alc b0606e2f16 If vm_map_find() is asked to allocate a superpage-aligned region of virtual ... addresses that is greater than a superpage in size but not a multiple of the superpage size, then vm_map_find() is not always expanding the kernel pmap to support the last few small pages being allocated. These failures are not commonplace, so this was first noticed by someone porting FreeBSD to a new architecture. Previously, we grew the kernel page table in vm_map_findspace() when we found the first available virtual address. This works most of the time because we always grow the kernel pmap or page table by an amount that is a multiple of the superpage size. Now, instead, we defer the call to pmap_growkernel() until we are committed to a range of virtual addresses in vm_map_insert(). In general, there is another reason to prefer calling pmap_growkernel() in vm_map_insert(). It makes it possible for someone to do the equivalent of an mmap(MAP_FIXED) on the kernel map.
