After this change, iwlwifi enters a nonfunctional state if wpa_supplicant is restarted, but "service netif restart wlan0" is enough to get it working again.

This is the struct mm->total_vm value adjusted to the corresponding units - bytes, kilobytes and pages. The fix is based on a fernape@ analysis.

There must be a code here that cannot be placed into the corresponding by common sense MI source and header files, i.e., code is machine independent, but ISA dependent. For the use_real_names knob, the code must be placed into the linux_socket.[c|h], however linux_socket is ISA dependent.

In our case the name was just `drmn`, which is not actually unique across devices. The other consumers are wireless drivers, which will benefit from this change. Generate the expected string for pci_name() to return.
