pud_clear wasn't setting the _PAGE_NEWPAGE bit, fooling tlb_flush into thinking that this area of the address space was up-to-date and not unmapping whatever was covered by the pud. This manifested itself as ldconfig on x86_64 complaining about the first library it looked at not being a valid ELF file. A config file is mapped at 0x4000000, as the only thing mapped under its pud, and unmapped. The unmapping caused a pud_clear, which, due to this bug, didn't actually unmap the config file data on the host. The first library is then mapped at the same location, but is not actually mapped on the host because accesses to it cause no page faults. As a result, ldconfig sees the old config file data.
