ARM: Disabling MMU and updating PC

In short, I would like to shut down all MMU (and cache) operations in a Linux context (from inside the Kernel), for debug purposes, just to run some tests. To be perfectly clear, I don’t intend that my system still be functional after that. About my setup: I’m currently fiddling with a Freescale Vybrid (VF610) – which integrates a Cortex

Linux /proc/pid/smaps proportional swap (like Pss but for swap)

In the case where there is shared memory involved, this seems to be an over-approximation of actual swap usage. For example when summing swap usage of a parent pid with its forked children, and if they
