[PATCH v2 0/9] KVM: x86: More emulator bugs

[Nadav Amit]

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
