This patch fixes a race in the command reference counting logic by putting
spinlocks around kobject_put() in the command_put function.
- Also added debug messages.
- Changed a memcpy to memcpy_fromio since we are reading from io space.

Here is a device driver for the IBM xSeries RSA service processor.
The ibmasm driver is mainly intended to be used in conjunction with a user space
API and systems management applications that need to get in-band access to
the service processor, such as sending commands or waiting for events.
For the remote video feature the driver relays remote mouse and keyboard
events to user space.
By itself the driver also allows the OS to make use the UART on the service
processor board as a regular serial line.
The user interface to the driver is a custom file system. It does not use sysfs since
the operations on the files are somewhat beyond the one file / one value rule for sysfs.
Since it is not strictly a char driver I put it into the drivers/misc directory.
The patch is fairly big, therefore I split it up into the file system part and the
everything-else part.
Here is the non-filesystem part:
