On a quad-core ARMv7 (e.g. my RPi), doubling ARG_MAX would use an additional 2MB of KVA (256K * (2 * 4 CPUs)). I don't = know if we have any non-terrible ways to see the kernel_map. I have some gdb scripts that I've only tested on amd64 but do handle submaps. I thought we= had a hack to export the kernel map via pid 0 for procstat -v, but that doesn't seem to work for me. --=20 You are receiving this mail because: You are the assignee for the bug.=
