IRQ mode already passes in a struct pt_regs from get_irq_regs(). FIQ mode passes in something similar but not identical to a struct pt_regs - FIQ mode stores the spsr of the interrupted mode in slot 17, while pt_regs expects orig_r0. Replace the existing mixture of void *regs, unsigned *regs, and struct pt_regs * const with const struct pt_regs *. Modify dump_regs not to print the spsr since it won't be there in a struct pt_regs anyways. Modify dump_allregs to highlight the mode that was interrupted, making spsr easy to find there.

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.
