The patch added a special get_unmapped_area for framebuffer which
was hooked to the file ops in drivers/video/fbmem.c.

This is needed since v2.6.29-rc1 where nommu vma management was
updated, and mmap of framebuffer caused kernel BUG panic. You may turn
on "Debug the global anon/private NOMMU mapping region tree" config to
such message.

As Documentation/nommu-mmap.txt said,
"To provide shareable character device support, a driver must provide
a file->f_op->get_unmapped_area() operation. The mmap() routines will
call this to get a proposed address for the mapping."

With this change, user space should call mmap for framebuffer using
shared map. Or it can try shared map first, then private map if
failed. This shared map usage is now consistent between mmu and nommu.

The sys_ file may not be a good place for this patch. But there is a
similar one for sparc. I tested a similar patch on nios2nommu, though
I don't have a blackfin board to test.

The cplbinfo was using d_path() to figure out which cpu/cplb was being
parsed.  As Al pointed out, this isn't exactly reliable as it assumes the
static VFS path to be unchanged, and it's just poor form.  So use the
proc_create_data() to properly (and internally) pass the exact cpu/cplb
requested to the parser function.

Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.

It also removes:
 - verbose GPL text(refer to the top level ./COPYING file)
 - file names (you are looking at the file)
 - bug url (it's in the ./MAINTAINERS file)
 - "or later" on GPL-2, when we did not have that right

It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

Convert Blackfin to use GENERIC_TIME via the arch_getoffset()
infrastructure, reducing the amount of arch specific code we need to
maintain.

I've taken my best swing at converting this, but I'm not 100% confident
I got it right.  My cross-compiler is now out of date (gcc4.2) so I
wasn't able to check if it compiled. Any assistance from arch
maintainers or testers to get this merged would be great.

There is no point in implementing a detect callback for the LTC4215
and LTC4245, as these devices can't be detected. It was there solely
to handle "force" module parameters to instantiate devices, but now
we have a better sysfs interface that can do the same.

So we can get rid of the ugly module parameters and the detect
callbacks. This shrinks the binary module sizes by 36% and 46%,
