"Multi processor systems are becoming more and more common place. Whilst most userspace code will run perfectly, and in some cases take advantage of SMP features without adding extra code, kernel space code should be written to be 'SMP aware' and 'SMP safe'. This series of articles will explain how this is done."
When you have more than one CPU, the same code can be executed on both (or more) CPUs at the same time. This can be an issue in routines such as those in figure 1, which initialises some imaginary device."
