Subject[PATCH v3 2/3] riscv: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO
Date
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.
