DIPM is unsupported or broken on sunxi. Trying to enable the power management policy med_power_with_dipm on an Allwinner A20 SoC based board leads to immediate I/O errors and the attached SATA disk disappears from the /dev filesystem. A reset (power cycle) is required to make the SATA controller or disk work again. The A10 and A20 SoC data sheets and manuals don't mention DIPM at all [1], so it's fair to assume that it's simply not supported. But even if it was, it should be considered broken and best be disabled in the ahci_sunxi driver.

This allows m68k q40 systems to switch from the deprecated IDE subsystem to libata. Enhance the byte-swapping falconide and pata_falcon platform drivers to accept an irq resource, for use on q40. Atari ST-DMA IRQ arrangements seem to co-exist with q40 IRQ arrangements without too much mess. The new IO resources were added solely for the purpose of making request_region() reservations identical to those made by q40ide: these regions aren't used for actual IO.

This allows m68k mac systems to switch from the deprecated IDE subsystem to libata. This was tested on my Quadra 630. I haven't tested it on my PowerBook 150 because I don't have a RAM adapter board for it. It appears that the hardware I tested doesn't need macide_clear_irq() or macide_test_irq(). If it did, the generic driver would not have worked. It's possible that those routines are needed for the PowerBook 150 but we can cross that bridge if and when we come to it. BTW, macide_clear_irq() appears to suffer from a race condition. The write to the interrupt flags register could have unintended side effects as it may alter other flag bits. Fortunately, all of the other bits are unused by Linux. When tested on my Quadra 630, the assignment *ide_ifr &= ~0x20 was observed to have no effect on bit 5, so it may be redundant anyway.

The driver overrides the error codes returned by platform_get_irq() to -ENXIO, so if it returns -EPROBE_DEFER, the driver would fail the probe permanently instead of the deferred probing.

Iff platform_get_irq() fails (or returns IRQ0) and thus the polling mode has to be used, ata_host_activate() hits the WARN_ON() due to 'irq_handler' parameter being non-NULL if the polling mode is selected. Let's only set the pointer to the driver's IRQ handler if platform_get_irq() returns a valid IRQ # -- this should avoid the unnecessary WARN_ON()...

iomap_max_page_shift is expected to contain a page shift, so it can't be a 'bool', has to be an 'unsigned int' And fix the default values: P4D_SHIFT is when huge iomap is allowed. However, on some architectures (eg: powerpc book3s/64), P4D_SHIFT is not a constant so it can't be used to initialise a static variable. So, initialise iomap_max_page_shift with a maximum shift supported by the architecture, it is gated by P4D_SHIFT in vmap_try_huge_p4d() anyway.
