Subject: [PATCH 0/6] Add an asm-generic cpuinfo_op declaration

From: Conor Dooley <conor.dooley@microchip.com>

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.

  asm-generic: add a cpuinfo_ops definition in shared code
  microblaze: use the asm-generic version of cpuinfo_op
  s390: use the asm-generic version of cpuinfo_op
  sh: use the asm-generic version of cpuinfo_op
  sparc: use the asm-generic version of cpuinfo_op
  x86: use the asm-generic version of cpuinfo_op
