[PATCH] common: memtest: Allow memtest to be interrupted

[PATCH] common: memtest: Allow memtest to be interrupted

[Marcel Hellwig]

This change will allow the user to interrupt a running memtest, as well
as poller to run in the background. This makes it possible to let a led
blink while doing a memtest to indicate process.
