For # example panic() will call smp_send_stop() early on which calls # stop_this_cpu() on other CPUs, then later in the reboot path, # pnv_restart() will call smp_send_stop() again, which hangs. # # Fix this by adding a special case to the stop_this_cpu() handler to # decrement the busy count, because it will never return. # # Now that the NMI/non-NMI versions of stop_this_cpu() are different, # split them out into separate functions rather than doing #ifdef tricks # to share the body between the two functions. # # Fixes: 6bed3237624e3 ("powerpc: use NMI IPI for smp_send_stop") # Reported-by: Abdul Haleem <abdhalee@linux.vnet.ibm.com> # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> #
