  "message": "x86/cpu/intel_epb: Don\u0027t rely on link order\n\nintel_epb_init() is called as a subsys_initcall() to register cpuhp\ncallbacks. The callbacks make use of get_cpu_device() which will return\nNULL unless register_cpu() has been called. register_cpu() is called\nfrom topology_init(), which is also a subsys_initcall().\n\nThis is fragile. Moving the register_cpu() to a different\nsubsys_initcall() leads to a NULL dereference during boot.\n\nMake intel_epb_init() a late_initcall(), user-space can\u0027t provide a\npolicy before this point anyway.\n\nSigned-off-by: James Morse \u003cjames.morse@arm.com\u003e\nSigned-off-by: Russell King (Oracle) \u003crmk+kernel@armlinux.org.uk\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\nReviewed-by: Gavin Shan \u003cgshan@redhat.com\u003e\nAcked-by: Rafael J.
