Now that disk and partition handlings are mostly unified, it's easy to
allow disk to have extended device number. This patch makes
add_disk() use extended device number if disk->minors is zero. Both
sd and ide-disk are updated to use this.
* sd_format_disk_name() is implemented which can generically determine
the drive name. This removes disk number restriction stemming from
limited device names.
* If sd index goes over SD_MAX_DISKS (which can be increased now BTW),
sd simply doesn't initialize minors letting block layer choose
extended device number.
* If CONFIG_DEBUG_EXT_DEVT is set, both sd and ide-disk always set
minors to 0 and use extended device numbers.

With previous changes, it's meaningless to limit the number of
partitions. Replace @ext_minors with GENHD_FL_EXT_DEVT such that
setting the flag allows the disk to have maximum number of allowed
partitions (only limited by the number of entries in parsed_partitions
as determined by MAX_PART constant).
This kills not-too-pretty alloc_disk_ext[_node]() functions and makes
@minors parameter to alloc_disk[_node]() unnecessary. The parameter
is left alone to avoid disturbing the users.

git commit 74811f355f causes crash at
module load (or boot) time on my machine with a hpt374 controller.
The reason for this is that for initializing second controller which sets
(hwif->dev == host->dev[1]) to true (1), adds 1 to a void ptr, which
advances it by one byte instead of advancing it by sizeof(hpt_info) bytes.
Because of this, all initialization functions get corrupted data in info
variable which causes a crash at boot time.
This patch fixes that and makes my machine boot again.

The guilty commit turned out to be 08da591e14
("ide: add ide_device_{get,put}() helpers"). ide_device_put() is called
before kref_put() in ide_cd_put() so IDE device is already gone by the time
ide_cd_release() is reached.
Fix it by calling ide_device_get() before kref_get() and ide_device_put()
after kref_put() in all affected device drivers.

reference on cd object (which could result in OOPS in ide_device_put() as

This controller supports UltraDMA up to mode 5 but it should be clocked with
at least twice the data strobe frequency, so enable mode 5 for 100+ MHz IDECLK.
While at it, start passing the correct device to clk_get() -- it worked anyway
but WTF? :-/

If this is actually unaligned the access of speed/max_speed above
is already broken and needs a get_unaligned. Otherwise it is
aligned and they can be removed.

While at it:
* it821x_chipsets[] -> it821x_chipset.
* Fix it821x_chipset's name field (as it is used for IT8211/8212).

While at it:
* Apply small fixes to messages (s/dma/DMA/, remove trailing '.', etc).
* Fix printk() call in ide_setup_pci_baseregs() to use KERN_INFO.
* Move printk() call from ide_pci_clear_simplex() to the caller.
* Cleanup do_ide_setup_pci_device() a bit.
* amd74xx.c: remove superfluous PCI device revision information.
* hpt366.c: fix two printk() calls in ->init_chipset to use KERN_INFO.
* pdc202xx_new.c: fix printk() call in ->init_chipset to use KERN_INFO.
* pdc202xx_old.c: fix driver message in pdc202xx_init_one().
* via82cxxx.c: fix driver warning message in via_init_one().

Replace ide_default_{io_base,irq}() inlines by legacy_{bases,irqs}[].
v2:
Add missing zero-ing of hws[] (caught during testing by Borislav Petkov).
v3:
Fix zero-oing of hws[] for _real_ this time.
There should be no functional changes caused by this patch.

Move ide_probe_legacy() call to ide_generic_init() so it fails
early if necessary and returns the proper error value (nowadays
ide_default_io_base() is used only by ide-generic).
