From d5654e156bc4d68a87bbaa6d7e020baceddf6e68 Mon Sep 17 00:00:00 2001 From: Helge Deller <deller@gmx.de> Date: Sat, 24 Mar 2018 21:18:25 +0100 Subject: [PATCH] parisc: Fix HPMC handler by increasing size to multiple of 16 bytes Make sure that the HPMC (High Priority Machine Check) handler is 16-byte aligned and that it's length in the IVT is a multiple of 16 bytes. Otherwise PDC may decide not to call the HPMC crash handler.
