Subject: pause_on_oops
Date: Sun, 17 Jun 2007 12:47:58 +0100 [thread overview]
Message-ID: <20070617114758.GA6716@flint.arm.linux.org.uk> (raw)
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.)
