The primary intent is that the triple (audit_arch, syscall_nr, arg1..arg6) should describe what system call is being called and what its arguments are. This patchset began as a series called "Prepare for PTRACE_GET_SYSCALL_INFO", then I merged it into a series called "ptrace: add PTRACE_GET_SYSCALL_INFO request" that also contains ptrace-specific changes. The ptrace-specific part, however, needs more attention to workaround problems on niche architectures like alpha, while the syscall_get_arch() part is straightforward, so I decided to split it out into a separate patchset that just prepares syscall_get_arch() for PTRACE_GET_SYSCALL_INFO: it adds syscall_get_arch() to those architectures that haven't implemented it yet, and then adds "struct task_struct *" argument to syscall_get_arch() on all architectures. All patches from this patchset have been already reviewed, so it's ready to be merged without waiting for the ptrace-specific part. As it's all about syscall_get_arch(), it should probably go via audit tree. Dmitry V.
