This patch http://harpoon.virt.bos.redhat.com/~ehabkost/kvm-patches/kvm-0006-avoid-cancelling-ide-dma.patch I think shall be ported to rhel6 and I posted it to rhvirt-patches with Message-ID: <20100721152112.GZ24928@random.random>
I'm uncertain about:
If ksm needs that, khugepaged may need that too.
This patch http://harpoon.virt.bos.redhat.com/~ehabkost/kvm-patches/kvm-enable-sysenter-on-32bit-guests-skype-fix.patch is already being handled in bug 614537
All others are obsolete or upstream.
Patch kvm-KSM-suspend-fix.patch is obsolete because RHEL6 will not freeze tasks that didn't run set_freezable. However I wonder if set_freezable()+try_to_freeze() is still needed in ksmd and khugepaged to avoid the risk of issuing I/O during suspend to disk if an allocation triggers swapout. Hugh thinks it's not needed but I'm discussing with him about this.
I'll open separate bug for rhvirt-patches with
In the end (after noticing kswapd also uses try_to_freeze) I opened bug 617430.
