This patch-set resolves several emulator bugs. Each fix is independent of the
others. The DR6 bug can occur during DR-access exit (regardless to
unrestricted mode, MMIO and SPT).
Changes in v2:
Introduced kvm_register_readl and kvm_register_writel which consider long-mode
and cs.l when reading the registers.
Fixing the register read to respect 32/64 bit in hypercall handling, CR exit
handling and VMX instructions handling.
Thanks for re-reviewing the patch
