PR 430/rtems
* include/rtems/score/watchdog.h: _Watchdog_Ticks_since_boot should
be a VOLATILE variable.
* src/watchdoginsert.c: 'restart' algorithm needs to enforce
reloading the list head in case a TICK interrupt during ISR_Flash()
modified the list. This is achieved by a proper VOLATILE cast.
Also _Watchdog_Sync_count++ should be protected by _ISR_Disable
(prevent corruption in case ISR calls watchdoginsert)
* src/watchdogadjust.c: ISR protection added.
* src/watchdogtickle.c: ISR protection added.
NOTE: PowerPC BSPs using the new exception processing MUST BE UPDATED
to maintain _ISR_Nest_level. See also PR288 which provides fixes
for the affected BSPs distributed with RTEMS.
