[PATCH] removing redundant ifdefs

[PATCH] removing redundant ifdefs

[Jiri Olsa]

removing redundant ifdefs.

the pattern is

	#ifdef DEF1
	...
	#ifdef DEF1
	...
	#endif
	...
	#endif

and removing the inner ifdef.

I found them using script all over the kernel so
I haven't even compile-tested some of them.

I CCed all the related maintainers, sorry if I put
any wrong one.

I've not received any patches relating to the above, but I seem to
have received everything else, including stuff for PPC and x86.

Maybe you've negated the list of people to send patches to?

This is wrong.  There is a preceding #ifdef CONFIG_ARCH_OMAP2PLUS, but
there's also a preceding #endif terminating that conditional section.

good catch but please add a body here. This problem appeared because

I made one after I spot one place like that.. it's simple
perl script, which spits many false warnings (attached).
I took what I thought was right. I did not want to spend
much time with that. ;)

Dunno. This looks a bit pointless. After all any ifdef __KERNEL__ is not
needed for this header file since its not exported.
So removing this ifdef and keep the other one doesn't make too much sense.

I don't see this in the linux-next version of ahci.c, so I'm dropping 
this patch.
