| * | KVM: MMU: Fix potential race setting upper shadow ptes on nonpae hostsAvi Kivity2008-07-201-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The direct mapped shadow code (used for real mode and two dimensional paging) sets upper-level ptes using direct assignment rather than calling set_shadow_pte(). A nonpae host will split this into two writes, which opens up a race if another vcpu accesses the same memory area. Fix by calling set_shadow_pte() instead of assigning directly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the guest issues a clflush in a mmio address, the instruction can trap into the hypervisor.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only abort guest entry if the timer count went from 0->1, since for 1->2 or larger the bit will either be set already or a timer irq will have been injected. Using atomic_inc_and_test() for it also introduces an SMP barrier to the LAPIC version (thought it was unecessary because of timer migration, but guest can be scheduled to a different pCPU between exit and kvm_vcpu_block(), so there is the possibility for a race).
