Re: [PATCH 4.9 000/107] 4.9.120-stable review

[Sebastian Gottschall <s.gottschall@dd-wrt.com>]

nother issue seen on xscale and as it affects all non SMP configured kernels


kernel/cpu.c: In function 'boot_cpu_hotplug_init':
kernel/cpu.c:2204:28: error: 'struct cpuhp_cpu_state' has no member 
named 'booted_once'
   this_cpu_write(cpuhp_state.booted_once, true);
