Merge tag 'trace-deferred-unwind-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull initial deferred unwind infrastructure from Steven Rostedt:
"This is the core infrastructure for the deferred unwinder that is
required for sframes[1]. Several other patch series are based on this
work although those patch series are not dependent on each other. In
order to simplify the development, having this core series upstream
will allow the other series to be worked on in parallel. The other
series are:

- The two patches to implement x86 support [2] [3]

- The s390 work [4]

- The perf work [5]

- The ftrace work [6]

- The sframe work [7]

And more is on the way.

The core infrastructure adds the following in kernel APIs:

- int unwind_user_faultable(struct unwind_stacktrace *trace);

Performs a user space stack trace that may fault user pages in.

- int unwind_deferred_init(struct unwind_work *work, unwind_callback_t func);

Allows a tracer to register with the unwind deferred
infrastructure.

- int unwind_deferred_request(struct unwind_work *work, u64 *cookie);

Used when a tracer request a deferred trace. Can be called from
interrupt or NMI context.

- void unwind_deferred_cancel(struct unwind_work *work);

Called by a tracer to unregister from the deferred unwind
infrastructure.

- void unwind_deferred_task_exit(struct task_struct *task);

Called by task exit code to flush any pending unwind requests.

- void unwind_task_init(struct task_struct *task);

Called by do_fork() to initialize the task struct for the
deferred unwinder.

- void unwind_task_free(struct task_struct *task);

Called by do_exit() to free up any resources used by the
deferred unwinder.

None of the above is actually compiled unless an architecture enables it,
which none currently do"

unwind_user/deferred: Add unwind_user_faultable()

Add a new API to retrieve a user space callstack called
unwind_user_faultable(). The difference between this user space stack
tracer from the current user space stack tracer is that this must be
called from faultable context as it may use routines to access user space
data that needs to be faulted in.

It can be safely called from entering or exiting a system call as the code
can still be faulted in there.

This code is based on work by Josh Poimboeuf's deferred unwinding code:

unwind_user: Add user space unwinding API with frame pointer support

Introduce a generic API for unwinding user stacks.

In order to expand user space unwinding to be able to handle more complex
scenarios, such as deferred unwinding and reading user space information,
create a generic interface that all architectures can use that support the
various unwinding methods.

This is an alternative method for handling user space stack traces from
the simple stack_trace_save_user() API. This does not replace that
interface, but this interface will be used to expand the functionality of
user space stack walking.

None of the structures introduced will be exposed to user space tooling.

Support for frame pointer unwinding is added. For an architecture to
support frame pointer unwinding it needs to enable
CONFIG_HAVE_UNWIND_USER_FP and define ARCH_INIT_USER_FP_FRAME.

By encoding the frame offsets in struct unwind_user_frame, much of this
code can also be reused for future unwinder implementations like sframe.
