Subject: [PATCH 07/13 v2] c6x: define syscall_get_arch()
Date: Sat, 10 Nov 2018 05:01:21 +0300 [thread overview]
Message-ID: <20181110020121.GA4908@altlinux.org> (raw)
In-Reply-To: <20181109031613.GG21511@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.
Signed-off-by: Dmitry V. Levin <ldv@altlinux.org>

v2: apparently, this architecture can be configured as big-endian,
so changed AUDIT_ARCH_C6X to be little-endian, and added AUDIT_ARCH_C6XBE.
