Let's not write it like some technical document: "Secure Memory
Encryption (SME) mask" is perfectly fine.

These bulletpoints talk about the "what" this patch does but they should
talk about the "why".
For example, it doesn't say why we're using _KERNPG_TABLE_NOENC when
building the initial pagetable and that would be an interesting piece of
information.

Right, I know we did talk about those but in looking more into the
future, you'd have to go educate people to use the __sme_pa* variants.
Otherwise, we'd have to go and fix up code on AMD SME machines because
someone used __pa_* variants where someone should have been using the
__sma_pa_* variants.
IOW, should we simply put sme_me_mask in the actual __pa* macro
definitions?
Or are we saying that the __sme_pa* versions you have above are
the special ones and we need them only in a handful of places like
load_cr3(), for example...? And the __pa_* ones should return the
physical address without the SME mask because callers don't need it?

You have a bunch of places where you remove the enc mask:
address & ~sme_me_mask
so you could do:
#define __sme_unmask(x) ((unsigned long)(x) & ~sme_me_mask)
and use it everywhere. "unmask" is what I could think of, there should
be a better, short name for it...

This conversion to *_pfn() is an unrelated cleanup. Pls carve it out and
put it in the front of the patchset as a separate patch.
