From: Zong Li <zong.li@xxxxxxxxxx> [ 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.
