[PATCH 1/5] drivers/regulator: Remove dead CONFIG_TWL4030_ALLOW_UNSUPPORTED

[PATCH 1/5] drivers/regulator: Remove dead CONFIG_TWL4030_ALLOW_UNSUPPORTED

[Christian Dietrich]

CONFIG_TWL4030_ALLOW_UNSUPPORTED doesn't exist in Kconfig and is never
defined anywhere else, therefore removing all references for it from
the source code.

[PATCH 3/5] drivers/rtc: Remove unneeded ifdef CONFIG_PM

[Christian Dietrich]

Because CONFIG_PM is a precondition to CONFIG_ACPI, the ifdef
CONFIG_PM within ifdef CONFIG_ACPI is redundant.

If you don't have other specific tree to merge your patch,
please get Andrew's help to do this.

We'll put appropriate versions of this code back in when we get the
rest of the functionality in the kernel.

[PATCH 5/5] Remove REDWOOD_5 and REDWOOD_6 config options and conditional code

[Christian Dietrich]

The config options for REDWOOD_[56] were commented out in the powerpc
Kconfig. The ifdefs referencing this options therefore are dead and all
references to this can be removed (Also dependencies in other KConfig
files).

REDWOOD_4 does not appear to be in the tree either so this mapping driver
should be deleted if the patch is otherwise acceptable.  Besides we
would express the info contained in this simple map driver the device tree
using physmap_of.

[PATCH 0/2] Removing dead code

[Christian Dietrich]

Hi all!

I merged the two patches from Christoph Egger[1] to remove the
REDWOOD_[456] config depends. And wrote a second patch, which removes
the redwood/mtd mapping module. I hope this is now acceptable to bring
it into the kernel, if this options are really dead.       

Regards

This seems fine with me.

The only question is which tree it coms through.  I'm happy to take it
in via mine if the netdev and MTD people are fine with that.  Otherwise,
my ack is below.

The patches are unnecssarly coupled by removing the REDWOOD_* symbols
in the MTD area before removing the files and Kconfig completely in
the second patch.  This could easily be eliminated by pushing the
two fragments into the second patch.

You know how slow MTD people may be sometimes, so I'd suggest you to
merge this via whatever tree. David is in CC, he'll complain if he is

[PATCH 2/2] Removed redwood/mtd mapping

[Christian Dietrich]

Removing the redwood mtd mapping driver, because all REDWOOD_[456]
configuration options were removed from the kernel, because they weren't
referenced anywhere.

Nack, you're missing the point of having this code here.

So if it isn't a config option, then perhaps it should be named CONFIG_?

I'm assuming you've got the wrong number negations there, but possibly.
Really it ought to be platform data I guess.

[PATCH 0/2] Removing dead code

[Christian Dietrich]

Hi all!
       
        As part of the VAMOS[0] research project at the University of
Erlangen we are looking at multiple integrity errors in linux'
configuration system.

        I've been running a check on the drivers/video sourcetree for
config Items not defined in Kconfig and found 2 such cases. Sourcecode
blocks depending on these Items are not reachable from a vanilla
kernel -- dead code. I've seen such dead blocks made on purpose
e.g. while integrating new features into the kernel but generally
they're just useless.

        Each of the patches in this patchset removes on such dead
config Item, I'd be glad if you consider applying them. I've been
doing deeper analysis of such issues before and can do so again but
I'm not so sure they were fastly usefull.

        I build the patches against a vanilla kernel in order to
try if the kernel compiles with this patches

        Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

Regards

        Christian Dietrich
