From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx> RISC-V is missing a prototype for cpuinfo_op. Rather than adding yet another `extern const struct seq_operations cpuinfo_op;` to an arch specific header file, create an asm-generic variant and migrate the existing arch variants there too. Obv. there are other archs that use cpuinfo_op but don't declare it and surely also have the same warning? I went for the minimum change here, but would be perfectly happy to extend the change to all archs if this change is worthwhile. Or just make a header in arch/riscv, any of the three work for me! If this isn't the approach I should've gone for, any direction would be great :) I tried pushing this last weekend to get LKP to test it but I got neither a build success nor a build failure email from it, so I figured I may as well just send the patches.. I wasn't too sure if this could be a single patch, so I split it out into a patch fixing the issue on RISC-V & copy-paste patches for each arch that I moved. Thanks, Conor.
