- Moved check for online cpu out of smp_prepare_cpu()
- Moved default declaration of smp_prepare_cpu() to kernel/cpu.c
- Removed lock_cpu_hotplug() from smp_prepare_cpu() to around it, since
its called from cpu_up() as well now.
- Removed clearing from cpu_present_map during cpu_offline as it breaks
using cpu_up() directly during a subsequent online operation.

Spotted by the Coverity checker as bug #666
akpm; there are several other `return 1;'s in there which aren't freeing

Initramfs initrd images do not need a ramdisk device, so remove this
restriction in Kconfig. BLK_DEV_RAM=n saves about 13k on i386. Also
without ramdisk device there's no need for "dry run", so initramfs unpacks
much faster.
People using cramfs, squashfs, or gzipped ext2/minix initrd images are
probably smart enough not to turn off ramdisk support by accident.

The /dev/mem and /dev/kmem write handlers weren't fully POSIX compliant in
that they wouldn't always force the file pointer to be updated when
returning success status.
The /dev/port write handler was inconsistent with the /dev/mem and
/dev/kmem handlers in that when encountering a -EFAULT condition after
already having written a number of items it would return -EFAULT rather
than the number of bytes written.

Remove the assumption that driver_register() returns the number of devices
bound to the driver. In fact, it returns zero for success or a negative
error value.
zorro_module_init() used the device count to automatically unregister and
unload drivers that found no devices. That might have worked at one time,
but has been broken for some time because zorro_register_driver() returned
either a negative error or a positive count (never zero). So it could only
unregister on failure, when it's not needed anyway.
This functionality could be resurrected in individual drivers by counting
devices in their .probe() methods.

WARNING: drivers/block/floppy.o - Section mismatch: reference to \
.init.data: from .text between 'init_module' (at offset 0x6976) and \

hysdn defines its own types: ulong, uint, uchar and word.
Problem is, the module_param macros rely upon some of those identifiers having
special meanings too. The net effect is that module_param() and friends
cannot be used in ISDN because of this namespace clash.
So remove the hysdn-private defines and open-code them all.

Make ata_set_mode() responsible for determining whether to take port
or device offline on failure. ata_dev_set_xfermode() and
ata_dev_set_mode() indicate error to the caller instead of disabling
port directly on failure. Also, for consistency, ata_dev_present()
check is done in ata_set_mode() instead of ata_dev_set_mode().

This patch implements ata_dev_disable() which prints a warning message
and takes @dev offline. Currently, this is done by explicitly
incrementing dev->class with case-by-case warning messages. Giving
user clear indication when libata gives up will be more important as
libata will be doing more retries.

libata core is being changed to disallow port/device disable on lower
layers. However, some LLDDs (sata_mv) directly disable port on
command failure. This patch makes ata_exec_internal() check whether a
port got disabled after an internal command. If it is, AC_ERR_SYSTEM
is added to err_mask and the port gets re-enabled.
As internal command failure results in device disable for drivers
which don't implement newer reset/EH callbacks, this change results in
no behavior change for single device per port controllers. For
slave-possible LLDDs which disable port on command failure, (1) such
drivers don't exist currently, (2) issuing command to the other device
of once-disabled port shouldn't result in catastrophe even if such
driver exists. So, this should be enough as a temporary measure.
