Convert sparc32 to use genirq.
Changes since v2:
- avoid moving function in sun4d_irq to make diff more readable (Josip Rodin)
- added patch that fixes build with floppy or LEON enabled
I broke that during my cleanup.
This is 1/5 - and should be applied to -next soon.
- converted leon to genirq
It was straight forward. I identified some dead code in leon_kernel
but I did not clean it up (stuff that reference eirq).
- converted pcic to genirq
I had missed this during the last rounds. I had also missed
that we either used sun4m_irq OR pcic irq support.
Note: I assume the handle_level_irq is the right handler for pcic too.
The TODO list contains only two items now:
- What to do with the smp4m_irq_rotate(cpu) functionality?
Can we just ignore it as we have a maximum of 4 CPUs
- Are the sun4d mask/unmask implementation buggy with respect
to cpu interrupts?
I do not know the sun4d platform - and has no HW to test on (yet at least)
I feel quite confident with most of the code-changes.
The sun4d stuff is where I am most unsafe.
If anyone can test it on real HW it would be great!
I will try to setup QEMU during the next week or two
to see if this can help me in more testing.
