Steven Rostedt (VMware) c2712b8581 kprobes, x86/ptrace.h: Make regs_get_kernel_stack_nth() not fault on bad stack
Andy had some concerns about using regs_get_kernel_stack_nth() in a new
function regs_get_kernel_argument() as if there's any error in the stack
code, it could cause a bad memory access. To be on the safe side, call
probe_kernel_read() on the stack address to be extra careful in accessing
the memory. A helper function, regs_get_kernel_stack_nth_addr(), was added
to just return the stack address (or NULL if not on the stack), that will be
used to find the address (and could be used by other functions) and read the
address with kernel_probe_read().

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
