All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0x6223c): Section mismatch in reference from the function init_subsystems() to the function .init.text:hyp_cpu_pm_init()
   The function init_subsystems() references
   the function __init hyp_cpu_pm_init().
   This is often because init_subsystems lacks a __init
   annotation or the annotation of hyp_cpu_pm_init is wrong.

   The function teardown_hyp_mode() references
   the function __init hyp_cpu_pm_exit().
   This is often because teardown_hyp_mode lacks a __init
   annotation or the annotation of hyp_cpu_pm_exit is wrong.

   This is often because kirin_pcie_probe lacks a __init
   annotation or the annotation of kirin_add_pcie_port.isra.4 is wrong.
