Andrew Morton suggested to move kprobes from kernel hacking menu, since kernel hacking menu is in-appropriate for the Kprobes. This patch moves Kprobes and Oprofile under instrumentation menu. (akpm: it's not a natural fit, but things like djprobes and the s390 guys' statistics library need a home) Signed-of-by: Prasanna S Panchamukhi <prasanna@in.ibm.com> Cc: Philippe Elie <phil.el@wanadoo.fr> Cc: John Levon <levon@movementarian.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

illegal uses of __init and __initdata after initialization.

Force the IOMMU to on even when you have less than 4GB of
|
|
memory and add debugging code. On overflow always panic. And
|
|
allow to enable IOMMU leak tracing. Can be disabled at boot
|
|
time with iommu=noforce. This will also enable scatter gather
|
|
list merging. Currently not recommended for production
|
|
code. When you use it make sure you have a big enough
|
|
IOMMU/AGP aperture. Most of the options enabled by this can
|
|
be set more finegrained using the iommu= command line
|
|
options. See Documentation/x86_64/boot-options.txt for more
|
|
details.

Add a simple leak tracer to the IOMMU code. This is useful when you

are debugging a buggy device driver that leaks IOMMU mappings.
