x86/mm: Unify remote INVLPG code There are currently three paths through the remote flush code: 1. full invalidation 2. single page invalidation using invlpg 3. ranged invalidation using invlpg This takes 2 and 3 and combines them in to a single path by making the single-page one just be the start and end be start plus a single page. This makes placement of our tracepoint easier.
