arch/x86: is not the correct prefix. Run git log on a file to figure out
what the usual prefix is. The file was checked in with 'purgatory', but I'd
prefer 'x86/purgatory' for future changes.

Please read 'Documentation...SubmittingPatches' and look for 'This patch'.

I give you an example for a changelog:

  Sparse emits several 'symbol not declared' warnings.

  Make the variables and functions, which have only file scope static.

Now try to map that to the advise in Documentation.

Thanks,
