Subject: [PATCH AUTOSEL 5.4 36/80] riscv: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO
Date: Mon, 26 Oct 2020 19:54:32 -0400	[thread overview]
Message-ID: <20201026235516.1025100-36-sashal@kernel.org> (raw)
In-Reply-To: <20201026235516.1025100-1-sashal@kernel.org>

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.
