Peter Zijlstra ae25884ad7 unwind_user/x86: Teach FP unwind about start of function
When userspace is interrupted at the start of a function, before we
get a chance to complete the frame, unwind will miss one caller.

X86 has a uprobe specific fixup for this, add bits to the generic
unwinder to support this.

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 reStructuredText 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.
