MIPS: Loongson: Reduce possible loop times and add log in do_thermal_timer() (17cbb070) · Commits · 戴 / test

Once the temperature of any CPUs is too high, it can power off immediately, no need to check the rest of CPUs, and it is better to print a log before power off, this is useful when analysis the abnormal issues. Signed-off-by:
