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.) -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of:
