Regarding the ARM Cortex-M3: Linux requires an MMU (Memory Management Unit). The ARM Cortex-M3 does not have one. It is impossible to run the mainline Linux kernel on the ARM Cortex-M3. However, there is a variant of the Linux kernel for MMUless processors called uCLinux. Linux on M3 Guide. ST's Application Note on uCLinux
