Subject: [PATCH RFC 18/20] tools arch uapi: Sync the uinstd.h header file for RISC-V
Date: Fri, 16 Feb 2024 16:57:36 -0800
Message-Id: <20240217005738.3744121-19-atishp@rivosinc.com>
In-Reply-To: <20240217005738.3744121-1-atishp@rivosinc.com>
References: <20240217005738.3744121-1-atishp@rivosinc.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

The uninstd.h has been changed since it's last sync. Update it so
that perf tool can use the new RISC-V specific syscall in perf tool.
