* new-exceptions/bspsupport/README,
new-exceptions/bspsupport/ppc_exc.S,
new-exceptions/bspsupport/ppc_exc_asm_macros.h,
new-exceptions/bspsupport/ppc_exc_bspsupp.h,
new-exceptions/bspsupport/ppc_exc_hdl.c,
new-exceptions/bspsupport/vectors_init.c:
Fixed and enabled stack-switching algorithm which figures out
if we already run on the ISR stack rather than relying on the
_ISR_Nest_level.
Added 'ppc_exc_crit_always_enabled' variable which defines
the semantics of critical interrupts.
Let asynchronous machine-check handling never call the dispatcher.
We don't want to disable MSR_ME ever (to avoid checkstops)
and hence asynchronous MEs must not use OS services anyways.
