#     powerpc/watchdog: read TB close to where it is used
#     
#     When taking watchdog actions, printing messages, comparing and
#     re-setting wd_smp_last_reset_tb, etc., read TB close to the point of use
#     and under wd_smp_lock or printing lock (if applicable).
#     
#     This should keep timebase mostly monotonic with kernel log messages, and
#     could prevent (in theory) a laggy CPU updating wd_smp_last_reset_tb to
#     something a long way in the past, and causing other CPUs to appear to be
#     stuck.
#     
#     These additional TB reads are all slowpath (lockup has been detected),
#     so performance does not matter.
