Log Message:
Fix for i386, functionality intended in:
http://mail-index.netbsd.org/source-changes/2018/09/23/msg099357.html

This should fix the build for both GENERIC and XEN3PAE_DOM0

This has not been boot tested on native or xen3pae

Notes: pmap_changeprot_local() seems to be x86_64 only.
I was a bit surprised by this initially, but I suspect that the table
protections are enforced via ring0/ring1 fencing rather than page protections

the gdt registration code in i386 is still messy. I will leave it as is
for now - to avoid a rabbit hole.
