Subject: [PATCH v5 16/22] KVM: riscv: selftests: Move sbi definitions to its own header file
Date: Wed,  3 Apr 2024 01:04:45 -0700
Message-Id: <20240403080452.1007601-17-atishp@rivosinc.com>

The SBI definitions will continue to grow. Move the sbi related
definitions to its own header file from processor.h
