[RFT v2 03/48] MIPS, irq: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

[Jiang Liu]

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.

Note: this patch has been queued by Ralf Baechle <ralf@linux-mips.org>.

[RFT v2 39/48] genirq, mips: Kill the first parameter 'irq' of irq_flow_handler_t

[Jiang Liu]

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.

To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

[RFT v2 46/48] genirq, irqchip: Kill the first parameter 'irq' of irq_flow_handler_t

[Jiang Liu]

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.

To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.
