Subject: linux-next: manual merge of the akpm-current tree with the printk
 tree

Hi all,

Today's linux-next merge of the akpm-current tree got a conflict in:

  lib/Kconfig.debug

between commit:

  57f5677e535b ("printf: add support for printing symbolic error names")

from the printk tree and patch:

  "kernel-hacking: move DEBUG_BUGVERBOSE to 'printk and dmesg options'"

from the akpm-current tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell

 +	  If you say Y here, the kernel's printf implementation will

+ 	  Say Y here to make BUG() panics output the file name and line number
+ 	  of the BUG call as well as the EIP and oops trace.  This aids
+ 	  debugging but costs about 70-100K of memory.
