Testing on that non-PCID systems showed an oddity with parts of the kernel image that are modified later in boot (when we set the kernel image read-only). We split a few of the PMD entries and the the old (early boot) values were being used for userspace.
I don't think this is a big deal. The most annoying thing is that it makes it harder to quickly validate that all of the things we set to global *should* be global. I'll put some examples of how this looks in the patch when I repost.
