On 64-bit, offset is always well\nbelow vma-\u003evm_end, so the clamp never fires and len stays unbounded\nagainst the LS_SIZE buffer returned by ctx-\u003eops-\u003eget_ls().\n\nReject offsets at or beyond LS_SIZE and clamp len to the remaining\nspace, mirroring the guard already used by spufs_mem_mmap_fault() and\nspufs_ps_fault().",
