BTW, I'm getting this warning on x86_64:
arch/x86_64/kernel/kgdb.c: In function `kgdb_arch_init':
arch/x86_64/kernel/kgdb.c:319: warning: passing arg 1 of
`atomic_notifier_chain_register' from incompatible pointer type
After looking at the code, it turned out that this is because 'die_chain'
is dealred as 'struct raw_notifier_head' (the same is true for i386), not
struct atomic_notifier_head'. I wonder what should be fixed, the declaration
or the call...
WBR, Sergei
