Subject: [PATCH v2 4/6] RISC-V: fault: Convert to VM_FAULT_ARCH_* codes
Date: Tue, 14 Mar 2023 20:03:57 -0700	[thread overview]
Message-ID: <20230315030359.14162-5-palmer@rivosinc.com> (raw)
In-Reply-To: <20230315030359.14162-1-palmer@rivosinc.com>

These conflict with VM_FAULT_HINDEX_MASK, so move to some designated
arch-specific values.
