This seems like a generally useful idea - certainly more valuable than

You might want to look at the BUG patches I wrote, which are currently
in -mm. I added general machinery to allow architectures to easily
implement BUG() efficiently (ie, with a minimal amount of BUG-related
icache pollution). If you were to store the BUG_ON expression, it would
be best to extend struct bug_entry and store it there - doing it in
asm-generic BUG_ON() means you still end up with code to set up the
printk in the mainline code path, and it also won't honour
CONFIG_DEBUG_BUGVERBOSE being disabled.
Thanks, I missed that change... I'll look into it.
