unwind_init() is currently a single function that initializes all of the unwind state. Split it into the following functions and call them appropriately: - unwind_init_from_regs() - initialize from regs passed by caller. - unwind_init_from_caller() - initialize for the current task from the caller of arch_stack_walk(). - unwind_init_from_task() - initialize from the saved state of a task other than the current task. In this case, the other task must not be running. This is done for two reasons: - the different ways of initializing are clear - specialized code can be added to each initializer in the future.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
