Patch series "Treewide: enable -Wmissing-prototypes", v3.
At this point, there are five architectures with a number of known
regressions: alpha, nios2, mips, sh and sparc. In the previous version of
this patch, I had turned off the missing prototype warnings for the 15
architectures that still had issues, but since there are only five left, I
think we can leave the rest to the maintainers (Cc'd here) as well.
The series is also likely to cause occasional build regressions on
linux-next as developers add new code that misses prototypes. Hopefully
this should be resolved by the time the patches make it into a release and
everyone gets the warnings right away.
This patch (of 6):
There is no global declaration for ida_dump() and no other callers, so
make it static to avoid this warning:
lib/test_ida.c:16:6: error: no previous prototype for 'ida_dump'

The IDA was declared on the stack instead of statically, so lockdep
triggered a warning that it was improperly initialised.

Move these tests from the userspace test-suite to the kernel test-suite.
Also convert check_ida_random to the new API.

Move as much as possible to kernel space; leave the parts in user space
that rely on checking memory allocation failures to detect the
transition between an exceptional entry and a bitmap.

Convert to new API and move to kernel space. Take the opportunity to
test the situation a little more thoroughly (ie at different offsets).
