Yes, and if it's for amd64 it should be done in the pmap layer, not
polluting the UVM layer all other architectures also use.


But did you even read what I wrote in my first mail? I said I intended to fix
it by using VM_MINUSER_ADDRESS or VM_MIN_ADDRESS. These are architecture-
dependent constants, which have nothing to do with UVM and nothing to do with
pmap.

I don't know what you are trying to demonstrate, and I have no idea why you
started this conversation about patching UVM, since it clearly wasn't my
intention.
