From 5d095e529694a55815a2d2370ca151fe2fe190d6 Mon Sep 17 00:00:00 2001 From: Zong Li Date: Mon, 31 Aug 2020 15:33:49 +0800 Subject: [PATCH] riscv: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO [ Upstream commit b5fca7c55f9fbab5ad732c3bce00f31af6ba5cfa ] 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 RISC-V at all even though ARCH_DLINFO will contain one NEW_AUX_ENT for the VDSO address.
