PATCH v3 1/20 ia64: move ia64_done_with_exception out of asm/uaccess.h

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.

Also relocate a couple of the automated asm --> linux uaccess conversions to preserve the linux and asm independent grouping, since we are in the file at that location anyway.

PATCH v3 2/20 ia64: ensure exception table search users include extable.h

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.

Hi Paul,
[auto build test ERROR on linus/master]
[also build test ERROR on v4.10-rc5 next-20170120]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
url:    https://github.com/0day-ci/linux/commits/Paul-Gortmaker/ia64-move-ia64_done_with_exception-out-of-asm-uaccess-h/20170123-004155
config: cris-etraxfs_defconfig (attached as .config)

Thanks (once again) for the build coverage. I'd actually built cris (allmodconfig) but strangely enough it didn't show this particular defconfig issue. I'll fix it to ensure this file includes extable.h

Paul.
