Changes in v2: - add [PATCH v2 2/6] (Peter Zijlstra) - remove [PATCH 4/5] and add [PATCH v2 5/6] - rebase onto the next-20250224 Hi all, As suggested by Peter Zijlstra below [1], this series aims to remove tlb_remove_page_ptdesc(). : Fundamentally tlb_remove_page() is about removing *pages* as from a PTE, : there should not be a page-table anywhere near here *ever*. : : Yes, some architectures use tlb_remove_page() for page-tables too, but : that is more or less an implementation detail that can be fixed. After this series, all architectures use tlb_remove_table() or tlb_remove_ptdesc() to remove the page table pages. In the future, once all architectures using tlb_remove_table() have also converted to using struct ptdesc (eg. powerpc), it may be possible to use only tlb_remove_ptdesc(). This series is based on next-20250224. Comments and suggestions are welcome!
