However, the value is stored as a signed integer, making the getter of the hv-spinlocks QOM property return -1 instead of 0xFFFFFFFF. Fix this by changing the type of X86CPU::hyperv_spinlock_attempts to uint32_t. This has no visible effect to guest operating systems, affecting just the behavior of the QOM getter.
