Okay, we need a #define __pte_free_tlb __pte_free_tlb.

__pmd_free_tlb is already a macro so the generic tlb.h should handle it correctly.
#define __pmd_free_tlb(tlb, pmd, addr) \
pgtable_free_tlb(tlb, pmd, false)
I'd move both __pmd_free_tlb and __pte_free_tlb into tlb.h such that the include order
of tlb.h vs pgalloc.h does not matter.
Are you fine with that?
