Shinya Kuribayashi 9e6f39698a MIPS: EMMA2RH: Remove EMMA2RH_CPU_CASCADE
Although all EMMAxxx SoCs can support IP2 and IP3 hardware interrupts,
current EMMA2RH plat_irq_dispatch() supports IP2 only.  We can make it
configurable in the future, but for the time being, would like to make
things explicitly allcated to IP2 in accordance with plat_irq_dispatch().

Shinya Kuribayashi eebacda40f MIPS: EMMA2RH: Remove useless CPU_IRQ_BASE
For historical reasons, we used to put MIPS CPU IRQs behind SoC-specific
IRQs in the queue, and have been using CPU_IRQ_BASE as MIPS_CPU_IRQ_BASE.
In recent years, however, we've brought it back to normal order, and now
CPU_IRQ_BASE just redefines the generic MIPS_CPU_IRQ_BASE.

At the same time, NUM_CPU_IRQ is also removed as useless.

Ralf Baechle 49316cbf0a MIPS: Eleminate filenames from comments
They tend to get not updated when files are moved around or copied and
lack any obvious use.  While at it zap some only too obvious comments and
as per Shinya's suggestion, add a copyright header to extable.c.

Shinya Kuribayashi 8da55bb258 MIPS: EMMA2RH: Use handle_edge_irq() handler for GPIO interrupts
EMMA's GPIO interrupts are latched by GPIO interrupt status register.
In this case, we're encouraged to use handle_edge_irq() handler.

The following changes are made along with replacing set_irq_chip() with
set_irq_chip_and_handler_name(,,handle_edge_irq,"edge"):

* Fix emma2rh_gpio_irq_ack not to disable interrupts

  With handle_edge_irq(), we're not expected to disable interrupts
  when chip->ack is served, so fix it accordingly.  We also add a new
  emma2rh_gpio_irq_mask_ack() for chip->mask_ack operation, instead.

* Remove emma2rh_gpio_irq_end(), as chip->end is no longer served.

Rusty Russell 1a8a51004a cpumask: remove references to struct irqaction's mask field.
Impact: cleanup

It's unused, since about 1995.  So remove all initialization of it in
preparation for actually removing the field.
