This patch adds a plat_irq_setup() symbol for sh4-202. Without
this fix it is impossible to build a working kernel using the
microdev_defconfig.

It seems we have gained an extraneous trailing ';' on one of the
wait loops in scif_sercon_putc().  Although this is completely
benign as the apparent payload is also the empty statement, it
invites error in the future.  Clean it up now.

Now that __initmv references the machvec section unconditionally
there have been cases where folks have been mistakenly flagging
non-machvec structures with the machvec section attribute (presumably
to shut up modpost). This leads to obscure breakage in earlyprintk
amongst other places and is rather non-obvious.

Add a simple sanity check to try and catch __initmv misuse and
panic early.

When generic_ptrace_peekdata() was merged, the break for these cases
ended up getting dropped, which lead to each PEEKTEXT/PEEKDATA op leaking
in to PEEKUSR and get_user_pages() always -EFAULTing. Add the break back
in.

SH-X3 has the FPU exceptions on different vectors completely,
patch in do_fpu_state_restore() to the proper vectors.

Results in a much happier userspace.

In the SH-3/4 TLB access violation path we were enabling IRQs before
the call in to trace_hardirqs_on(), which ended up triggering:

        if (DEBUG_LOCKS_WARN_ON(!irqs_disabled()))
                return;

in kernel/lockdep.c:2031. Fix this up by removing the early re-enable,
we were already re-enabling IRQs post-trace_hardirqs_on() already, so
the semantics are now as was initially intended.

Do not follow the frame pointers (/proc/X/task/1/stat) unless we were
compiled with them.
