Hi Jiang,
https://patchwork.kernel.org/patch/1781291/
You said that the bootmem allocator doesn't touch *highmem pages*, so
highmem zones' managed_pages is set to the accurate value "spanned_pages
- absent_pages" in function free_area_init_core() and won't be updated
anymore. Why it doesn't touch *highmem pages*? Could you point out where
you figure out this?
