      pci_iounmap'2: Electric Boogaloo: try to make sense of it all · 316e8d79
      Linus Torvalds authored
      Nathan Chancellor reports that the recent change to pci_iounmap in
      commit 9caea000 ("parisc: Declare pci_iounmap() parisc version only
      when CONFIG_PCI enabled") causes build errors on arm64.
      
      It took me about two hours to convince myself that I think I know what
      the logic of that mess of #ifdef's in the <asm-generic/io.h> header file
      really aim to do, and rewrite it to be easier to follow.
      
      Famous last words.
      
      Anyway, the code has now been lifted from that grotty header file into
      lib/pci_iomap.c, and has fairly extensive comments about what the logic
      is.  It also avoids indirecting through another confusing (and badly
      named) helper function that has other preprocessor config conditionals.
      
      Let's see what odd architecture did something else strange in this area
      to break things.  But my arm64 cross build is clean.
      
      Fixes: 9caea000 ("parisc: Declare pci_iounmap() parisc version only when CONFIG_PCI enabled")
