Changeset c47ad8e in rtems for cpukit/libmisc/stackchk/check.c

stackchk: Add SMP support

Check the interrupt stacks of all processors. Set up the interrupt
stack of the current processor for high water testing in the thread
begin extension. This must be done after multi-threading started, since
the initialization stacks may reuse the interrupt stacks. Disable
thread dispatching in SMP configurations to prevent thread migration.
Writing to the interrupt stack is only safe if done from the
corresponding processor in thread context.

Update #3459.
