Subject: [PATCH v5 09/25] hexagon: define remaining syscall_get_* functions
Date: Mon, 10 Dec 2018 07:29:48 +0300 [thread overview]
Message-ID: <20181210042948.GI6131@altlinux.org> (raw)
In-Reply-To: 20181210042352.GA6092@altlinux.org
syscall_get_* functions are required to be implemented on all
architectures in order to extend the generic ptrace API with
PTRACE_GET_SYSCALL_INFO request.
This adds remaining 3 syscall_get_* functions as documented in
asm-generic/syscall.h: syscall_get_error, syscall_get_return_value,
and syscall_get_arch.
