mmu_notifiers: remove leftover stub macros

thejh · akpm00 · commit 49c69504f4d3 · 2025-05-31T22:46:13.000-07:00
Commit ec8832d ("mmu_notifiers: don't invalidate secondary TLBs as part of mmu_notifier_invalidate_range_end()") removed the main definitions of {ptep,pmdp_huge,pudp_huge}_clear_flush_notify; just their !CONFIG_MMU_NOTIFIER stubs are left behind, remove them.
