d92280d132 sh: migrate exception table users off module.h and onto extable.h
These files were only including module.h for exception table
related functions.  We've now separated that content out into its
own file "extable.h" so now move over to that and avoid all the
extra header content in module.h that we don't really need to compile
these files.

One uses "print_modules" so that prevents us removing module.h in
that case, however.

We also delete a duplicate prototype that doesn't need to exist, as
it duplicates content in extable.h

cad1c0dfc8 sh/uaccess: fix sparse errors
virtio wants to read bitwise types from userspace using get_user.  At the
moment this triggers sparse errors, since the value is passed through an
integer.

Fix that up using __force.

cba8df4be3 sh: use the new generic strnlen_user() function
This discards both the _32 and _64 versions in favour of the consolidated
generic one.

0e100e11bd sh: switch to generic strncpy_from_user().
This kills off the special sh32/64 versions and adopts the generic
version. It should be possible to optimize this for SH-4A unaligned
loads, but this is a corner case that can be supported incrementally.

6de9c6481d sh: Proper __put_user_asm() size mismatch fix.
This fixes up the workaround in 2b4b2bb42137c779ef0084de5df66ff21b4cd86e
and cleans up __put_user_asm() to get the sizing right from the onset.

f15cbe6f1a sh: migrate to arch/sh/include/
This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac.

Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.
