I wouldn't recommend the above option. It affects alignment of some things
and as you found it makes the kernel bigger. There are also some things in
that assume 4KB pages.
I expect we're past the point where there are any significant
obstacles to userspace support. Most platforms successfully support
multiple page sizes these days.
page boundary on parisc and it doesn't overlap text.
