Hi,

this series removes or replaces preempt_disable() and local_irq_save()
sections which are problematic on PREEMPT_RT.
Patch 3 makes netif_rx() work from any context after I found suggestions
for it in an old thread. Should that work, then the context-specific
variants could be removed.

Sebastian

Let's CC Toke, lest it escapes his attention.
