+ printk(KERN_EMERG "------------[ cut here ]------------\n");
I'm not sure I'm big on the cut here marker.
Yeah, its a bit of a toss-up. powerpc wants to hide the warn flag somewhere, which either means having a different structure, or using the fields differently. CONFIG_DEBUG_BUGVERBOSE supporters (ie, i386) want to make the structure completely empty in the !DEBUG_BUGVERBOSE case (which doesn't currently happen).i386 implements CONFIG_DEBUG_BUGVERBOSE, but x86-64 and powerpc do
not. This should probably be made more consistent.
It looks like if you do this you _might_ be able to share struct
bug_entry, or at least have consistent members for each arch. Which
would eliminate some of the inlines you have for accessing the bug
struct.
It needed a bit of work to get going on powerpc:
