Subject: [PATCH 02/23] Staging: add TAINT_CRAP flag to drivers/staging modules
Patch-mainline: 2.6.28

We need to add a flag for all code that is in the drivers/staging/
directory to prevent all other kernel developers from worrying about
issues here, and to notify users that the drivers might not be as good
as they are normally used to.

Based on code from Andreas Gruenbacher and Jeff Mahoney to provide a
TAINT flag for the support level of a kernel module in the Novell
enterprise kernel release.

This is the code that actually modifies the modules, adding the flag to
any files in the drivers/staging directory.
