[PATCH] No I/O ports on the DECstation

[PATCH] No I/O ports on the DECstation

[Maciej W. Rozycki]

 There are no I/O ports on the DECstation whatsoever in any configuration 
as neither the CPU nor the peripheral buses used have a concept of such.

Stale patch?

 Not at all, it would seem.  It applies just fine and is still required as 
of 2.6.22-rc3.  These CONFIG_HAS_IOMEM and CONFIG_HAS_IOPORT options are 
pretty recent anyway -- there is little chance for anything about them to 
get stale yet.

Git is pickier than patch.  Anything that will still be applied by patch
with a fuzz will be rejected by git-apply.  For good reason, I several
times ended with a corrupt tree thanks to patch happily (miss-)applying
some stale patch with fuzz.  Heck, it hit akpm recently ...

Anyway, this one was trivial and is in my queue tree now.

 I see -- I'll regenerate patches if they are fuzzy then.  Thanks.
