This patch corrects a mistake introduced by commit
5d9b36eec8ca6abe03da91efdfc7b5861525bd43
and reported by Nitin A Kamble.
The pop instruction restores ECX and EIP if read_std() fails and if we have a
REP prefix,
but at this level ECX and EIP are not saved (and not modified). We don't have
to

Applied, thanks.

Do not meddle in the internals of kernels, for they are subtle and quick to
panic.

I try to implement the guest reboot support, but I found there is an
stranger #PF VM Exit in guest real mode cs:ip=f000:1 which is
problemtic and current shadow won;t handle. I then try to
use -no-kvm-irqchip and get same error.
Can somebody give me more information if you ever successfully

Patch doesn't apply. Can you rebase to latest kvm.git?
Also, fix whitespace issues reported by 'git apply'.

Correct me if I'm wrong, perhaps it's the bug Nitin is hunting.
There is always something wrong in the management in the REP prefix.
I think what is happen is:
- we have a REP prefix, we save ECX and EIP.
- we set c->dst to emulate a "stos"
- goto writeback
- writeback: we try a "write_emulated(

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

Hi Avi,
Sound good! But what can we do before the merge? You know, we have to
spend much effort maintaining our patches with sync with upstream tree. Do you
have an interim solution or proposal for merging IA64 code? Thanks.
