From b6356a013a0933e42556c2def806f06caf459acf Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Mon, 1 Jul 2013 17:01:56 +0300 Subject: remoteproc: free carveout memories only after unmapping them It is not preferable to have the allocated pages for carveout memories freed before they are unmapped. The code that deals with the cleanup of carveout memories is therefore moved after the corresponding mapping entries were cleaned up. This is mostly a no-op since the remote processors are already stopped when the cleanup function is called, but this will make the cleanup code follow the exact reverse path of allocation.
