Commit fa8c3d65538a ("KVM: arm64: Keep nVHE EL2 vector installed")
inadvertently changed clang's inlining decisions around
hyp_cpu_pm_{init,exit}, causing the following section mismatch
warnings:
WARNING: modpost: vmlinux.o(.text+0x95c6c): Section mismatch in
reference from the function kvm_arch_init() to the function
.init.text:hyp_cpu_pm_exit()
The function kvm_arch_init() references
the function __init hyp_cpu_pm_exit().
This is often because kvm_arch_init lacks a __init
annotation or the annotation of hyp_cpu_pm_exit is wrong.
WARNING: modpost: vmlinux.o(.text+0x97054): 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.
Remove the __init annotation so that there are no warnings regardless
of
how functions are inlined.
