Btw, I remember that the whole vmalloc magic in zsmalloc was only giving
a small benefit for a few niche use cases. Given that it generally has
very strange interaction with the vmalloc core, including using various
APIs not used by any driver I'm going to ask once again why we can't
just drop the CONFIG_ZSMALLOC_PGTABLE_MAPPING case entirely?
