I noticed that insert_resource() incorrectly handles the case of an
existing parent resource with the same ending address as a newly added
child.  This results in incorrect nesting, like the following:

	# cat /proc/ioports
	<snip>
	002f0000-002fffff : PCI Bus #48
	  00200000-002fffff : /pci@800000020000003
	</snip>

PIO handlers under CONFIG_IDE_TASKFILE_IO=n are never used for bio

directly instead of calling ide_[un]map_buffer().

'cat /proc/ide/hdx/identify' generates REQ_DRIVE_TASKFILE request
(for WIN_PIDENTIFY command) even for devices controlled by ide-cd.
All other drivers don't try to retry such requests.
