Hence this is only # broken on big endian (or technically ELFv1). # # Fix it by using the proper accessor, which is ppc_function_entry(). # Result is we get a stack trace such as: # # .trace_graph_return+0x134/0x160 # .ftrace_return_to_handler+0x94/0x140 # .return_to_handler+0x20/0x40 # .return_to_handler+0x0/0x40 (.shared_cede_loop+0x48/0x130) # .return_to_handler+0x0/0x40 (.cpuidle_enter_state+0xa0/0x690) # .return_to_handler+0x0/0x40 (.cpuidle_enter+0x44/0x70) # .return_to_handler+0x0/0x40 (.call_cpuidle+0x68/0xc0) # .return_to_handler+0x0/0x40 (.do_idle+0x37c/0x400) # .return_to_handler+0x0/0x40 (.cpu_startup_entry+0x30/0x50) # .rest_init+0x224/0x348 # # Fixes: 7d56c65a6ff9 ("powerpc/ftrace: Remove mod_return_to_handler") # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Reviewed-by: Naveen N.
