           Summary: CPU_STACK_ALIGNMENT for m68k Incorrect
           Product: RTEMS
           Version: HEAD
          Platform: m68k
        OS/Version: RTEMS
            Status: NEW
          Severity: major
          Priority: P3
         Component: cpukit
        AssignedTo: joel.sherrill at oarcorp.com
        ReportedBy: bswimley at advanced.pro

The latest change to isr.c has broken the setup of _CPU_Interrupt_stack_high
with the CPU_STACK_ALIGNMENT set in cpu.h for the m68k.

Currently, this is set to 0 which results in _CPU_Interrupt_stack_high = 0
which is an invalid (e.g. NULL) pointer.

Changing CPU_STACK_ALIGNMENT to 1 in cpu.h corrects this problem.
