This moves all the common parts for the Sparc, Sparc64 and PowerPC
of_device.c files into drivers/of/device.c.
Apart from the simple move, Sparc gains of_match_node() and a call to
of_node_put in of_release_dev(). PowerPC gains better recovery if

Now that ide-floppy supports SG_IO we can add support for SCSI ioctls
(except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET
ones - we can add them later iff really needed).
While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from
generic_ide_ioctl():
- This prevents ide-{disk,tape,scsi} device drivers from obtaining
REQ_TYPE_BLOCK_PC type requests which are currently unsupported by
these drivers and which are potentially harmful (as reported by Andrew).
- There is no functionality loss since aforementioned ioctls will now be
handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using
ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl()
(for devices using ide-cd driver).

The driver used to depend on BIOS settings for deciding whether it is OK

Various old IDE drivers go mapping ROM devices for no apparent reason and
without using the ROM mapping API we now have. They don't actually use
the ROM they map and the new libata drivers are happy without it being

Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of
the cmpxchg64b feature and enables compilation of the set_64bit() family.
Since the option is dependent on PAE, and since KVM depends on set_64bit(),
this effectively disables KVM on i386 nopae.
Simplify by removing the config option altogether: the boot check is made
dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed
without constraints. It is up to users to check for the feature flag (KVM
does not as virtualiation extensions imply its existence).
