* [PATCH v2 0/2] ia64: make use of new extable.h header

[v1 -> v2: de-pollute uaccess.h as per what Al Viro's comments implied]

We forked the exception table content out of module.h into a new
extable.h file[1].  We temporarily include extable.h into the module.h
itself.  Now we work our way across the arch independent and arch
specific files needing just exception table content, and move them
off module.h and onto extable.h

Once that is done, we can remove the extable.h from module.h and in
doing it like this, we avoid introducing build failures into the git
history.

Here we move ia64 onto using the new arch independent header, and in
doing so we also spin off some ia64 exception specific code from the
uaccess.h header into a new exception.h header -- based on comments
from the v1 review[2] suggesting uaccess.h was not the best place.

Build tested on the intermediate and final commit on top of linux-next,
but not runtime tested.

Paul.

Move ia64_done_with_exception out of asm/uaccess.h (which is widely
used) and into asm/exception.h (like ARM has) and then ensure the
few callers of it include this new header.

Most of the other C content in asm files is implemented in macro form.
So we do that conversion at the same time as the move.

There are two C exception prototypes that move along with the macro.
One of them will become redundant when we switch over to using the
<linux/extable.h> instead of <linux/module.h> header in a subsequent
commit.

We start with a delete of a duplicate prototype in asm/exception.h
that no longer needs to exist, as it duplicates content in extable.h
and since that header is so small, there is no point trying to
avoid using it.

Then we make sure anyone using search_exception_tables directly or
via the ia64_done_with_exception macro has included extable.h

In the process, we remove an include of moduleloader.h that was
apparently not really required; it would have been fetching in
module.h and hence the previous location of the exception search
function prototypes, but we need not rely on that anymore.
