  "description": "In the Linux kernel, the following vulnerability has been resolved:  fs/proc/task_mmu: do not warn on seeing non-migration pmd entry  Patch series \u0022mm/hmm: A fix and a selftest\u0022, v3.  Patch 1 fixes a stale warning present from the time when only migration softleaf entries were supported at the PMD level.  Patch 2 adds some code into hmm-tests.c which exercises the pagemap path for PMD device-private entries.   This patch (of 2):  pagemap_pmd_range_thp() warns if a non-present PMD is not a migration entry.  This became false once device-private entries at the PMD level were added.  Therefore, remove the stale migration-only assertion.",
