We have not been swapping out kernel stacks since forever.  So just
allocate the uarea with zeroed pages using km_alloc(9).  Adjust the amd64
code that creates a guard page at the top of the kernel stack to use
pmap_kremove(9) instead of pmap_remove(9) to reflect that the uarea no
longer uses "managed" pages.
