2011-03-29sparc: Use the new genirq functionalityThomas Gleixner2-24/+9
Make use of the new features in genirq: 1) Set the chip flag IRCHIP_EOI_IF_HANDLED, which ensures in the core code that irq_eoi() is only called when the interrupt was handled. That removes the extra status check in the callback. 2) Use the preflow handler, which is called from the fasteoi core code before the device handler. That avoids another status check and the open coded handler redirection. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: sparclinux@vger.kernel.org

2011-03-29powerpc: xilinx: Cleanup flow type handlingThomas Gleixner1-6/+0
The core irq_set_type() function updates the flow type when the chip callback returns 0. So setting the type is bogus. The core also updates the LEVEL flag. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-03-29powerpc: uic: Cleanup flow type handlingThomas Gleixner1-17/+10
The core irq_set_type() function updates the flow type when the chip callback returns 0. So setting the type is bogus. The core also updates IRQ_LEVEL. Use irq_data to get the level type information in the chip functions. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-03-29powerpc: mpic: Cleanup flow type handlingThomas Gleixner1-17/+12
The core irq_set_type() function updates the flow type when the chip callback returns 0. So setting the type is bogus. The new core code allows to update the type in irq_data and return IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for setting the IRQ_LEVEL flag. Retrieve the IRQ_LEVEL information from irq_data which avoids a redundant sparse irq lookup as well. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

The core irq_set_type() function updates the flow type when the chip callback returns 0. So setting the type is bogus. The level flag is updated in the core as well. Use the proper accessors for setting the irq handlers. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2011-03-29powerpc: cell: Fix the irq_desc accessThomas Gleixner1-8/+1
The core irq_set_type() function updates the flow type when the chip callback returns 0. It also updates irq_data, so this can be used in irq_ack() to check for the level bit. That avoids a redundant sparse irq lookup. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2011-03-29powerpc: media5200: Remove pointless set_irq_type()Thomas Gleixner1-6/+1
The irq chip has no irq_set_type() callback. So calling the call is pointless. Set IRQ_LEVEL via the proper accessor. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

This includes conversion to new style irq_chip functions, and correctly enabling/disabling per-CPU interrupts. The hardware interrupt bit to irq number mapping is now done with a flexible map, instead of by bit twiddling the irq number.

2011-03-29ia64: iosapic: Remove redundant mask from ack()Thomas Gleixner1-9/+0
The core code calls mask_ack() which calls irq_ack() and irq_mask() for the case where an interrupt is disabled and marked pending. That seems to be a leftover from the old __do_IRQ() mode. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
