Greg Ungerer bbc6f1ba50 m68k: set register a2 to current if MMU enabled on ColdFire ... Virtual memory m68k systems build with register a2 dedicated to being the current proc pointer (non-MMU don't do this). Add code to the ColdFire interrupt and exception processing to set this on entry, and at context switch time. We use the same GET_CURRENT() macro that MMU enabled code uses - modifying it so that the assembler is ColdFire clean.
