Serious flaw in all new_exception_processing powerpc BSPs (except mpc8260)

I recently experienced corruption of the 'tick' queue
on my PPC. I finally found out one of the reasons:


on which the watchdog timer queues rely
is still not maintained on 'new_exception_processing' style
PPC BSPs other than mpc8260ads!!!

PR288 never made it to other PPC BSPs.

watch out

As a quick workaround, you can delete the line


in the file cpukit/score/src/watchdoginsert.c
(your IRQ latency will go up)

(old_exception_processing BSPs are not flawed)
