Subject: [patch] kvm: fix GFP_KERNEL allocation in atomic section in
kvm_dev_ioctl_create_vcpu()
From: Ingo Molnar <mingo@xxxxxxx>
fix a GFP_KERNEL allocation in atomic section bug:
kvm_dev_ioctl_create_vcpu() called kvm_mmu_init(), which calls
alloc_pages(), while holding the vcpu. The fix is to set up the MMU
state earlier, it does not require a loaded CPU state.
Yes it does. It calls nonpaging_init_context() which calls
vmx_set_cr3() which promptly trashes address space of the VM that
previously ran on that vcpu (or, if there were none, logs a vmwrite error).
