Dave,

A few more fixes intended for 2.6.39...

This includes an iwlagn fix where we were checking an address insted
of the value stored there in a wait_event_timeout (oops!), an ath9k
fix for an invalid memory access, another ath9k fix for a regression
that could cause a stuck tx queue, and an orinoco fix to zero-out an
invalid pointer to prevent a resulting invalid pointer dereference.

Please let me know if there are problems!

Thanks,

John
