From 3146bc64d12377a74dbda12b96ea32da3774ae07 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Mon, 25 Jul 2016 16:59:52 +0100 Subject: arm64: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO 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 arm64 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 arm64 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.
