We used to assign IRQs for all devices at boot-time, before any drivers
claimed devices. The following commits:
30fdfb929e82 ("PCI: Add a call to pci_assign_irq() in pci_device_probe()")
0e4c2eeb758a ("alpha/PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping hooks")
changed this so we now call pci_assign_irq() from pci_device_probe() when
we call a driver's probe method.
The ide_scan_pcibus() path (enabled by CONFIG_IDEPCI_PCIBUS_ORDER) bypasses
pci_device_probe() so it can guarantee devices are claimed in order of PCI
bus address. It calls the driver's probe method directly, so it misses the
pci_assign_irq() call (and other PCI initialization functions), which
causes failures like this:
ide0: disabled, no IRQ
ide0: failed to initialize IDE interface
ide0: disabling port

CMD64x_IDE: probe of 0000:00:02.0 failed with error -16
ide_generic: please use "probe_mask=0x3f" module parameter for probing

ide0: disabling port
Fix the IRQ allocation issue by calling pci_assign_irq() from
ide_scan_pcidev() before probing the IDE PCI drivers, so that IRQs for a
given PCI device are allocated for the IDE PCI drivers to use them for
device configuration.
Fixes: 30fdfb929e82 ("PCI: Add a call to pci_assign_irq() in pci_device_probe()")
Fixes: 0e4c2eeb758a ("alpha/PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping hooks")

The Kconfig for this support is currently:
config IDEPCI_PCIBUS_ORDER
bool "Probe IDE PCI devices in the PCI bus order (DEPRECATED)"
...meaning that it currently is not being built as a module by anyone.
Lets change the initcall to be the equivalent device_initcall, so that
when reading the driver code, there is no doubt it is builtin-only.
Unlike other similar changes, we leave the module.h header to be
included since this code interacts with other drivers and needs to
know what a struct module is.

This option is obsolete and can be removed safely.
It allows us to remove the pci_get_device_reverse() function from the
PCI core.

- ide_scan_pcibus() can become static
- instead of ide_scan_pci() we can use ide_scan_pcibus() directly
in module_init()

* Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c
file for probing PCI host drivers registered with IDE core (special case
for built-in IDE and CONFIG_IDEPCI_PCIBUS_ORDER=y) and then take care of
the ordering in which all IDE host drivers are probed when IDE is built-in
during link time.
* Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch
specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris
arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific).
* Move probing of ide-cris (cris arch specific) host driver before cmd640
(x86 arch specific).
* Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends
on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300
(h8300 arch specific).
* Add "probe_vlb" kernel parameter to cmd640 host driver and update
Documentation/ide.txt accordingly.
* Make IDE_ARM config option visible so it can also be disabled if needed.
* Remove bogus comment from ide.c while at it.
v2:
* Fix two issues spotted by Sergei:
- replace ENOMEM error value by ENOENT in ide-h8300 host driver
- fix MODULE_PARM_DESC() in cmd640 host driver
