Add kmem_valloc
Functions like vremap need to allocate some virtual addressing space
before making their own mapping. kmem_alloc_wired can be used for that
but that wastes memory.
* vm/vm_kern.c (kmem_valloc): New function.
* vm/vm_kern.h (kmem_valloc): New prototype.
* linux/dev/glue/kmem.c (vremap): Call kmem_valloc instead of
kmem_alloc_wired. Also check that `offset' is aligned on a page.
