Subject[PATCH] cpu/hotplug: Remove unused but set variable in _cpu_down()
Date
After commit 530e9b76ae8f ("cpu/hotplug: Remove obsolete cpu hotplug
register/unregister functions"), the variable hasdied in _cpu_down() is
set but no longer read, leading to the following GCC warning when
building with 'make W=1':

kernel/cpu.c:767:7: warning: variable ‘hasdied’ set but not used [-Wunused-but-set-variable]

Fix it by removing the variable.
