Yap, sounds like you marked a bisection step incorrectly, which lead
into the wrong direction. How reliable is your reproducer?
Also, do the bisection as Paolo suggested:
* try 45bdbcfdf241.
* then do
$ git bisect start v4.5-rc1 v4.4
which marks -rc1 as bad and 4.4 as good.
While you're doing that bisect, do what Paolo said by applying the diff
here
https://lkml.kernel.org/r/570EADD2.8030300@xxxxxxxxxx
when the bisection point you're at at each step contains
46896c73c1a4 ("KVM: svm: add support for RDTSCP")
You should apply the above hunk by doing
$ patch -p1 --dry-run -i /tmp/hunk
If it applies fine, you then apply it
$ patch -p1 -i /tmp/hunk
All clear?
If not, do not hesitate to ask.
Thanks
