Subject: [PATCH 12/13] riscv: define syscall_get_arch()
Date: Fri, 9 Nov 2018 06:17:13 +0300 [thread overview]
Message-ID: <20181109031712.GL21511@altlinux.org> (raw)
Message-ID: <20181109031713.FdS_VWFY-8IfqkbcHdqIP6Lxs3u3eIliBI-p77GuNxY@z> (raw)
In-Reply-To: <20181109031303.GA20906@altlinux.org>
syscall_get_arch() is required to be implemented on all architectures
that use tracehook_report_syscall_entry() in order to extend
the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.
