Sebastian, thanks for there, I picked up only the Ethernet patches:

5ce7f3f46f6b net: neterion: s2io: Replace in_interrupt() for context detection
dc5e8bfcd12e net: forcedeth: Replace context and lock check with a lockdep_assert()
beca92820dc4 net: tlan: Replace in_irq() usage

Please repost the wireless stuff for Kalle to linux-wireless@vger, 
and repost the fsl stuff separately (our patchwork queue is huge, 
I can't keep this waiting for an ack any longer).
