linprocfs(4): Fixup process size in the /proc/pid/stat file

Browse Source 
According to the Linux sources the kernel exposes a proces virtual
memory size via proc filesystem into the three files - stat, status
and statm. 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.
