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

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

Nadav Amit (9):
  KVM: x86: bit-ops emulation ignores offset on 64-bit
  KVM: x86: Wrong emulation on 'xadd X, X'
  KVM: x86: Inter privilage level ret emulation is not implemeneted
  KVM: x86: emulation of dword cmov on long-mode should clear [63:32]
  KVM: x86: NOP emulation clears (incorrectly) the high 32-bits of RAX
  KVM: x86: check DR6/7 high-bits are clear only on long-mode
  KVM: x86: Hypercall handling does not considers opsize correctly
  KVM: vmx: handle_cr ignores 32/64-bit mode
  KVM: vmx: vmx instructions handling does not consider cs.l
