| Subject: riscv: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO |
| |
| From: Zong Li <zong.li@sifive.com> |
| |
| [ 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. |
