  Hi,

This series aims at fixing the performance degradation reported
by Intel QE. I managed to reproduce the issue, and this series
fixes it.

I only tested the first test case provided in the Bz[0], but wanted
to send early for Intel QE to try and confirm it solves the issue.

I will work on reproducing the other test cases, and see if this
also fixes them.

Thanks to Intel QE team for finding this issue.
Maxime
