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
