Per X/Open CAE Spec Issue 5 Version 2, change the buffer size argument of
...
readlink() from type `int' to type `size_t'. This isn't an ABI change, since
the calling convention of our only LP64 platform (the Alpha) already promotes
this argument to a `long'.
This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

Make proc0 use the statically-allocate vmspace0 again, and make it use
...
the kernel's pmap, since proc0 (and other that share its address space)
are kernel-only processes, and should never contain userspace mappings.
This makes it easier to detect errors, like entering user mappings
for kernel processes, in pmap modules, and makes some sense, considering
that kernel processes are really just "thread contexts" for the kernel.
