Hi, In my kernel startup I see the memory usage printed as: Memory: 125312k/131072k available (1977k kernel code, 5648k reserved, 287k data, 1664k init, 0k highmem) I wonder where the reserved pages are used for and how we can minimize it for small memory systems. In my search I see that in arcm/mips/mm/init.c there are zero-pages allocated and put to reserved. Where are the zero pages used for and can we do without ? thanks in advance, Niels Sterrenburg
