mod.rs	machine: expose guest RAM snapshot query data Implement the snapshot memory QMP queries for standard and micro machines. The mapping query returns RAM host addresses, sizes, page sizes, and flat image offsets. The page-state query returns resident and zero-page bitmaps using the same flat RAM order. Residency is derived from /proc/self/pagemap rather than mincore, so pages that are present in RAM or swapped out are both reported as resident. Swapped pages are read back in before zero-page classification so the empty bitmap remains exact. All snapshot memory query paths require the VM to be paused so external tools observe a stable memory layout and page-state view. The dirty bitmap command uses the UFFD query-and-reset helper introduced earlier. (cherry picked from commit 8eb89af3594843237af9edcc64d6cc34b0ab4f4f)	10 天前
