Wanpeng Li 34226b6b70 KVM: X86: Fix setup the virt_spin_lock_key before static key get initialized ... static_key_disable_cpuslocked(): static key 'virt_spin_lock_key+0x0/0x20' used before call to jump_label_init() WARNING: CPU: 0 PID: 0 at kernel/jump_label.c:161 static_key_disable_cpuslocked+0x61/0x80 RIP: 0010:static_key_disable_cpuslocked+0x61/0x80 Call Trace: static_key_disable+0x16/0x20 start_kernel+0x192/0x4b3 secondary_startup_64+0xa5/0xb0 Qspinlock will be choosed when dedicated pCPUs are available, however, the static virt_spin_lock_key is set in kvm_spinlock_init() before jump_label_init() has been called, which will result in a WARN(). This patch fixes it by delaying the virt_spin_lock_key setup to .smp_prepare_cpus().
