I understand. There is a better solution, which is to use threaded
interrupts where needed.

But I must confess that I am disappointed that you still fail to see
how the pca953x
patch actually eliminates the need for serialization. But I don't
think there is much
point in going on about that.

The phy driver should be rewritten to use a threaded handler, it will
solve my particular problem.
And in the meantime, I have been promised to get the phy interrupts ofloaded
to real CPU interrupt lines :-)

Oh, I still think that the disable_irq_nosync documentaiton is misleading.
Functions that are allowed in a particular context should not call functions
that are not allowed to be called in that context. But now I know :-)
