Message-ID: <lsq.1539530741.897349794@decadent.org.uk> Date: Sun, 14 Oct 2018 16:25:41 +0100 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "Helge Deller" <deller@....de> Subject: [PATCH 3.16 061/366] parisc: Fix HPMC handler by increasing size to multiple of 16 bytes 3.16.60-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Helge Deller <deller@....de> commit d5654e156bc4d68a87bbaa6d7e020baceddf6e68 upstream. 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.
