In <asm/sysreg.h> we have macros to convert the names of general purpose registers (GPRs) into integer constants, which we use to manually build the encoding for `MRS` and `MSR` instructions where we can't rely on the assembler to do so for us. In subsequent patches we'll need to map the same GPR names to integer constants so that we can use this to build metadata for exception fixups. So that the we can use the mappings elsewhere, factor out the definitions into a new <asm/gpr-num.h> header, renaming the definitions to align with this "GPR num" naming for clarity. There should be no functional change as a result of this patch.

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.
