SubjectRe: [PATCH -rt] ide: fix interrupts processing issue with preempt-able hardirqs

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. )
