[PATCH v3] powerpc: Rework lazy-interrupt handling

2012-02-13 Thread Benjamin Herrenschmidt
The current implementation of lazy interrupts handling has some issues that this tries to address. Except on iSeries, we don't do the various workarounds we need to do on re-enable when returning from an interrupt, which can do an implicit re-enable, and thus we may still lose or get delayed decre
