actually no, that should not happen - if -rt loses an IRQ then something 
broke in the threaded IRQ code. It's supposed to be a drop-in, 
compatible IRQ flow with no driver changes needed.

( also, please do not Cc: mainline maintainers to RFC -rt patches, let
  the -rt maintainers sort out the need for any patch propagation - once 
  the patches are sufficiently cooked. Thanks. )
