Hello, I've added instrumentation into mm/bootm.c __free and __reserve functions to report how many accumulative pages the bootmem allocator reserves prior to the zone allocator. I had expected this figure multiplied by the page size to equal the 'reserved' figure in the 'Memory: 126604k/126604k available, 4468k reserved, 0K highmem' line. However this seems to be 'out by one'. I'm using the latest stable kernel.org kernel, with versatile_defconfig (ARM) - it seems that the figure reported by arch/arm/mm/init.c (mem_init) - reports the reserved pages - via the PageReserved macro's - a page size smaller (4468k) than that found via my instrumentation (4472k). Is a page being lost somewhere? not accounted for? or is it being reserved elsewhere?
