    x86/mm, KVM: Fix warning when !CONFIG_PREEMPT_COUNT · 4c07f904
    Roman Kagan authored
    A recent commit:
    
      d6e41f11 ("x86/mm, KVM: Teach KVM's VMX code that CR3 isn't a constant")
    
    introduced a VM_WARN_ON(!in_atomic()) which generates false positives
    on every VM entry on !CONFIG_PREEMPT_COUNT kernels.
    
    Replace it with a test for preemptible(), which appears to match the
    original intent and works across different CONFIG_PREEMPT* variations.
