Greg, could you please pull in the following upstream commit?
It was backported to kernels > 6.0, but with newer binutils it's probably
needed for kernels < 6.0 as well:

commit b5b2a02bcaac7c287694aa0db4837a07bf178626
Author: Ben Hutchings <benh@xxxxxxxxxx>
Date:   Thu Jun 15 00:00:02 2023 +0200

    parisc: Delete redundant register definitions in <asm/assembly.h>

    We define sp and ipsw in <asm/asmregs.h> using ".reg", and when using
    current binutils (snapshot 2.40.50.20230611) the definitions in
    <asm/assembly.h> using "=" conflict with those:

    arch/parisc/include/asm/assembly.h: Assembler messages:
    arch/parisc/include/asm/assembly.h:93: Error: symbol `sp' is already defined
    arch/parisc/include/asm/assembly.h:95: Error: symbol `ipsw' is already defined

    Delete the duplicate definitions in <asm/assembly.h>.

    Also delete the definition of gp, which isn't used anywhere.
