[NET]: Fix possible dev_deactivate race condition
The function dev_deactivate is supposed to only return when
all outstanding transmissions have completed. Unfortunately
it is possible for store operations in the

[IRQ]: Fix synchronize_irq races with IRQ handler
As it is some callers of synchronize_irq rely on memory barriers
to provide synchronisation against the IRQ handlers. For example,
the tg3 driver does
tp-irq_sync = 1;
What may happen is that action can either float upwards to give
spin_lock
action
set IRQ_INPROGRESS
spin_unlock
spin_lock
clear IRQ_INPROGRESS
spin_unlock
or it can float downwards to give
spin_lock
set IRQ_INPROGRESS

That's why I think this patch is in fact the only one that
solves all the races in this thread. The case that it solves
which the lock/unlock patch does not is the one where action
flows downwards past the clearing of IRQ_INPROGRESS. I
The whole lock/set IRQ_INPROGRESS/unlock path can then only happen
before the locked section above, in which case we see and wait nicely
and all is good, or after, in which case the store to foo will be
visible to the IRQ handler as it will be ordered with the unlock in the
code above.

First of all let's agree on some basic assumptions:

Not unless you mean a pair of spin lock/unlock as in

Your commit message doesn't give any reason why you are doing this, or

Hey, I appreciate it, but I do think that the spinlock only to
immediately unlock it again is pretty horrid.
I'm convinced that there should be some way to do this without actually
taking the lock. I

[POWERPC] Switch to generic WARN_ON()/BUG_ON()
Not using the ppc-specific WARN_ON/BUG_ON constructs actually saves about
4K text on a ppc64_defconfig. The main reason seems to be that prepping
the arguments to the conditional trap instructions is more work than
just doing a compare and branch.

Only if the minimum interrupt latency is less than 1 decrementer
