From 65f2475f1f3b46086dfeef9ba882ea3d9d909d57 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 27 Jul 2016 16:56:47 +1000 Subject: [PATCH] ppc: Use a helper to generate "LE unsupported" alignment interrupts Some operations aren't allowed in LE mode, use a helper rather than open coding the exception generation.
