Subject: [PATCH v6 05/27] arc: define syscall_get_arch()
Date: Thu, 13 Dec 2018 20:21:47 +0300 [thread overview]
Message-ID: <20181213172146.GE6024@altlinux.org> (raw)
In-Reply-To: 20181213171833.GA5240@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.
