Change subject: util/cbmem: mmap underflow on low addresses
......................................................................


Patch Set 3:

> $ sudo ./cbmem -l
> Failed to mmap /dev/mem: Operation not permitted

EPERM means you're violating STRICT_DEVMEM, that check happens before the crash. Either compile a kernel without STRICT_DEVMEM or try this on a machine where the relevant physical address range would not be normal memory.
