The fact is, volatile on data structures is a bug. It's a wart in the C

For architectures that don't have a volatile atomic_ts constructs like
while (atomic_read(something)); might result in endless loops since a
barrier() is missing which forces the compiler to generate code that
actually reads memory contents.

Just saw this while grepping for atomic_reads in a while loops.
Maybe we should re-add the volatile to atomic_t. Not sure.
I think whatever

drivers/ssb/Kconfig has already a depends on HAS_IOMEM which should
prevent SSB from being selected. But appearantly it looks like this
doesn't matter at all if it gets selected from somewhere else.
So add an explicit depends on HAS_IOMEM to the Broadcom

As spinlock debugging still does not work with the qeth driver I
want to pick up the discussion.
Does something like the patch below work?
But this all begs the question, what happens if you want to
dig into the internals of a protocol which is built modular and
hasn't been loaded yet?
works for me... I guess there must be a better way to make
sure that any networking driver's initcall is made before inet_init?
Signed-off-by: Heiko Carstens [EMAIL PROTECTED]
We could make inet_init() a subsystem init but I vaguely recall
that we were doing that at one point and it broke
callchain: inet_init() - inet_register_protosw() - synchronize_net()
The problem can't be rcu_init(), that gets done very early
in init/main.c
Maybe it's some timer or something else specific to s390?
It could also be that there's perhaps nothing to context
switch to, thus the RCU
before inet_init?
