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)\nwould probably be making the impact of this a lot worse.","state":0,"publishedAt":"2025-04-16T14:12:05.849+00:00","modifiedAt":"2026-10-15T21:51:57.12+00:00","affected":[{"ecosystem":"Vendor
