[PATCH] dcdbas: force SMI to happen when expected

[Stuart_Hayes]

The dcdbas driver can do an I/O write to cause a SMI to occur.  On some systems I/O writes are posted in the chipset and don't complete immediately.  This can result in the SMI happening at a later time.  This can result in random failures since the SMI handler expects the EBX register to contain a pointer, and the handler can write to memory.

Performing an I/O read to the same address as the I/O write will force the I/O write to complete.  The patch is against the 2.6.37 kernel and has been tested.
