Folk,
It seems that arch maintainers weren't copied on the "pause on oops"
patch (dd287796d608fcdc3fe5e8fdb5bf762a8f1bc32a) which introduced
some generic infrastructure (oops_enter, oops_exit). This has been
subsequently used by lockdep to disable itself when an oops occurs.
AFAICS only i386, powerpc and x86_64 call oops_enter() and oops_exit().
However, ARM, MIPS, S390, SH, Sparc64, and UML support lockdep, so
presumably it would be a good idea if they too were aware of these
functions.
I suggest _at least_ mips, s390, sh, sparc64 and uml folk look into
adding support to their die() functions (and check whether their
die functions are missing any other useful functionality.)

I've added it on SH now, thanks Russell.
