From 1bdd7c7ea8a711efcb5141663865cc1f7e4e824d Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 30 May 2012 14:45:21 +0200 Subject: linux-user: fix multi-threaded /proc/self/maps When reading our faked /proc/self/maps from a secondary thread, we get an invalid stack entry. This is because ts->stack_base is not initialized in non-primary threads. However, ts->info is, and the stack layout information we're looking for is there too. So let's use that one instead!
