This is a note to let you know that I've just added the patch titled MIPS: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mips-define-at_vector_size_arch-for-arch_dlinfo.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 233b2ca181f20674ecad11be90b00814911ce345 Mon Sep 17 00:00:00 2001 From: James Hogan <jhogan@xxxxxxxxxx> Date: Mon, 25 Jul 2016 16:59:50 +0100 Subject: MIPS: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO From: James Hogan <james.hogan@xxxxxxxxxx> commit 233b2ca181f20674ecad11be90b00814911ce345 upstream. AT_VECTOR_SIZE_ARCH should be defined with the maximum number of NEW_AUX_ENT entries that ARCH_DLINFO can contain, but it wasn't defined for MIPS at all even though ARCH_DLINFO will contain one NEW_AUX_ENT for the VDSO address. This shouldn't be a problem as AT_VECTOR_SIZE_BASE includes space for AT_BASE_PLATFORM which MIPS doesn't use, but lets define it now and add the comment above ARCH_DLINFO as found in several other architectures to remind future modifiers of ARCH_DLINFO to keep AT_VECTOR_SIZE_ARCH up to date.
