Guoyun Sun ad1df95419 mips/vdso: Support mremap() for vDSO ... vDSO VMA address is saved in mm_context for the purpose of using restorer from vDSO page to return to userspace after signal handling. In Checkpoint Restore in Userspace (CRIU) project we place vDSO VMA on restore back to the place where it was on the dump. Make vDSO code track the VMA address by supplying .mremap() fops the same way it's done for x86 and arm by: commit b059a453b1 ("x86/vdso: Add mremap hook to vm_special_mapping") commit 739586951b ("arm64/vdso: Support mremap() for vDSO").
