Subject: [PATCH v2 07/15] arc: define syscall_get_arch()
Date: Tue, 20 Nov 2018 03:15:49 +0300	[thread overview]
Message-ID: <20181120001549.GG11387@altlinux.org> (raw)
In-Reply-To: <20181120001128.GA11300@altlinux.org>

syscall_get_arch() is required to be implemented on all architectures
in order to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO
request.

Signed-off-by: Dmitry V. Levin <ldv@altlinux.org>
Acked-by: Vineet Gupta <vgupta@synopsys.com>
