- Get rid of linearize() callback in emulation ops.
v1->v2
- add segment check and mask rcx/rdi correctly drying increment.
Gleb Natapov (5):
KVM: Provide userspace IO exit completion callback.
KVM: emulator: make x86 emulation modes enum instead of defines
KVM: emulator: move some address manipulation function out of
emulator code.
KVM: emulator: make linearize() callable from outside of emulator
KVM: Provide fast path for "rep ins" emulation if possible.
