• 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.
