o) Move back to 4K pages due to the misalignment of USRSTACK, which causes
   problems with all existing binaries.  If we're ever willing to totally
   break kernel-userland ABI (I doubt we will be) we can move to 8K pages.
o) Add a function kmem_alloc_nofault_space() which is just like
   kmem_alloc_nofault() but which allows the user to specify a space
   finding constraint other than VMFS_ANY_SPACE.
o) Add a space VMFS_TLB_ALIGNED_SPACE which gives architecture-dependent
   alignment of the address to meet TLB alignment requirements using a
   new function, pmap_align_tlb, which on MIPS ensures no TLB entry
   sharing by rounding up to 2 * PAGE_SIZE.  We can use this instead of
   the old hacks to allocate extra pages for kstack, etc.
