From dce79affd5d04e9cbabe35016eda55213b9b36f6 Mon Sep 17 00:00:00 2001 From: Daniel Jacobowitz Date: Fri, 30 Sep 2005 00:17:35 +0100 Subject: [PATCH] [ARM] 2941/1: Fix running legacy binaries from a soft-float root filesystem with CONFIG_IWMMXT. Patch from Daniel Jacobowitz Thread flags are inherited on fork(). In order for a binary which has the iWMMXt coprocessor enabled to run a binary which needs the FPA emulation, we need to explicitly clear TIF_USING_IWMMXT if we are not going to set it.
