The following patches fix fallout from the main 2.6.24 KVM merge. An
exception is the movnti emulation patch, which adds support for Linux
2.6.16 guests.

The patches can be found in kvm.git in the branch kvm-updates-2.6.24.
There is also a branch kvm-updates-2.6.25 which will form the basis of
the next merge window submission.

Please review the patches and let me know if something is wrong or if
a patch is missing.



Laurent, I believe the following patch (in kvm-updates-2.6.25) needs to go into 2.6.24 as well. Can you comment on this?

KVM: x86 emulator: Correct management of REP prefix

This patch corrects some errors appearing when we have an emulation failure
on an operation using REP prefix.

When x86_emulate_insn() fails, saving EIP and ECX is not enough as emulation
should have modified other registers like RSI or RDI. Moreover, the emulation
can fail on the writeback, and in this case we are not able to restore
registers.

At beginning of x86_emulate_insn(), we restore registers from vcpu as they were
not modified by x86d_decode_insn() and we save EIP to be able to restore it
in case of failure.
