Fix the X86 version by making it behave the\nsame way.\n\nCurrently, X86 only uses this information for the following two purposes,\nwhich I think means the issue doesn't have much impact:\n\n - In native_flush_tlb_multi() for checking if lazy TLB CPUs need to be\n   IPI'd to avoid issues with speculative page table walks.\n - In Hyper-V TLB paravirtualization, again for lazy TLB stuff.\n\nThe patch \"x86/mm: only invalidate final translations with INVLPGB\" which\nis currently under review (see\n<https://lore.kernel.org/all/20241230175550.4046587-13-riel@surriel.com/>)\nwould probably be
