ide: fix probing for hosts with serialized or IRQ sharing interfaces
After hwif_register_devices() IDE devices are ready to be used so
the way in which ide_device_add() works currently is racy for hosts
with serialized / IRQ sharing interfaces.
Fix ide_device_add() by looping over interfaces for probe_hwif(),
hwif_init() and hwif_register_devices() operations.
ide: don't try to unregister interfaces if 'initializing' in ide_register_hw()
Host drivers using ide_register_hw() and 'initializing == 1':
* ide-pnp
- depends on ISA
* ide_arm
- ARM arch specific
- initialized before all other host drivers
* ide-cris
- CRIS arch specific => IDE_ARCH_OBSOLETE_INIT is not defined
- broken
* ide-h8300
- H8300 arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI
* buddha/q40/gayle/macide/falconide
- M68K arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI
Since the only host drivers which probe interfaces before the above ones are:
* ali14xx/dtc2278/ht6560b/qd65xx/umc8672
- depend on ISA
- require IDE_ARCH_OBSOLETE_INIT=y to work
* PCI ones
- depend on PCI
don't try to unregister interfaces if 'initializing == 1' in ide_register_hw()
(it is possible that built-in host drivers will claim all IDE interfaces but
later ide-pnp host driver will try to unregister them - this change fixes it).
Also skip hwif->hold check if 'initializing == 1' since it is set only by:
* pmac
- PPC && PMAC specific => no ISA
* au1xxx-ide
- MIPS && SOC_AU1200 specific => no ISA
and use ide_find_port() helper to find free ide_hwifs[] slot.

I left fixing ide-cris after "kill dma_on/dma_off_quietly() methods"
patch because:
* Currently this driver is broken: cris_dma_on() (returns 'int')

won't build.
* ->ide_dma_on method was missing so the driver OOPS-es on attempt
to enable DMA.
* drive->using_dma was never set/cleared so DMA wouldn't be used anyway.
Unfortunately it seems that ide-cris stays broken even after this patch:
* V10: <asm/arch-v10/ide.h> needs fixing
- ide_init_default_hwifs() should be removed
(IDE core no longer uses it)
- same for ide_init_hwif_ports() and ide_default_{irq,io_base}()

[S390] dasd: add hyper PAV support to DASD device driver, part 1
Parallel access volumes (PAV) is a storage server feature, that allows
to start multiple channel programs on the same DASD in parallel. It
defines alias devices which can be used as alternative paths to the
same disk. With the old base PAV support we only needed rudimentary
functionality in the DASD device driver. As the mapping between base
and alias devices was static, we just had to export an identifier
(uid) and could leave the combining of devices to external layers
like a device mapper multipath.
Now hyper PAV removes the requirement to dedicate alias devices to
specific base devices. Instead each alias devices can be combined with
multiple base device on a per request basis. This requires full
support by the DASD device driver as now each channel program itself
has to identify the target base device.
The changes to the dasd device driver and the ECKD discipline are:
- Separate subchannel device representation (dasd_device) from block
device representation (dasd_block). Only base devices are block
devices.
- Gather information about base and alias devices and possible
combinations.
- For each request decide which dasd_device should be used (base or
alias) and build specific channel program.
- Support summary unit checks, which allow the storage server to
upgrade / downgrade between base and hyper PAV at runtime (support
is mandatory).
