Subject: [PATCH] obsolete config in kernel source (BUFFER_DEBUG)

Hi all!

	As part of the VAMOS[0] research project at the University of
Erlangen we're checking referential integrity between kernel KConfig
options and in-code Conditional blocks.

	This is another example of a block of code, here since ever
and never compiled in modern history. Couldn't find out much more
about it but as it can't be set for ages it might be wise to just
remove it right now?

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

Regards

	Christoph Egger

Subject: [PATCH] Remove config SCSI_DC395x_TRMS1040_TRADMAP

There's exactly one in source-check for SCSI_DC395x_TRMS1040_TRADMAP
imported with the first git revision and no corresponding KConfig Item
ever. Removing this single left-over block from the kernel config.
