parisc: fix frame pointer in ftrace_regs_caller()
The current code in ftrace_regs_caller() doesn't assign %r3 to contain the address of the current frame. This is hidden if the kernel is compiled with FRAME_POINTER, but without it just crashes because it tries to dereference an arbitrary address. Fix this by always setting %r3 to the current stack frame. Signed-off-by: Sven Schnelle <svens@stackframe.org> Signed-off-by: Helge Deller <deller@gmx.de>

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.
