Subject: [PATCH 06/14] hexagon: define syscall_get_arch()
Date: Wed, 9 Jan 2019 15:43:04 +0300	[thread overview]
Message-ID: <20190109124303.GF11981@altlinux.org> (raw)
In-Reply-To: 20190109124044.GA11935@altlinux.org

syscall_get_arch() is required to be implemented on all architectures
in addition to already implemented syscall_get_nr(),
syscall_get_arguments(), syscall_get_error(), and
syscall_get_return_value() functions in order to extend the generic
ptrace API with PTRACE_GET_SYSCALL_INFO request.
