| |
The delayed irq disable functionality introduced a bug due to retriggering level type interrupts in case of the delayed disable. The resulting problem was discussed and debugged here: http://marc.info/?l=linux-kernel&m=118202978609968&w=2
The resend of a level type interrupt is unnessecary and adds extra noise to the system. Level type interrupts are resent by hardware when they are still active at irq_enable(). The hard-/soft-ware resend is only useful for edge type interrupts.
The following patch series addresses the problem and fixes an unnoticed mismerge which affects the same area as well.
