This is worrisome. If you look at pagemap.h, it includes a pile of things which could easily themsleves try to include tlb.h via some path or another. I fear that this patch will cause explosions with some config and/or architecture.
If you like, tlb.h is a low-level sort of thing whereas pagemap.h is a higher-level VFS thing. It is more appropriate that pagemap.h be including tlb.h.
So I think a better fix would be better, but I'm not able to suggest what, as there is little detail about the failure here and I can find no mention of page_cache_release and release_pages in asm-generic/tlb.h. Presumably they're getting pulled in via some macro and then instantiated in some inline function or something?
