    Subject[PATCH 0/9 v2] KVM: Nested SVM fixes and tracepoint conversion
    Hi Avi, Marcelo,

    this series of patches contains bugfixes for the Nested SVM code and the
    conversion of Nested SVM debugging to tracepoints. The fixes are:

    1) A patch Alex already sent (1/9) but which was not yet
    applied. It fixes a lost event_inj problem when we emulate
    a vmrun and a vmexit without entering the guest in
    the meantime.

    2) The patch 2/9 fixes a schedule() while atomic bug in the
    Nested SVM code. The KVM interrupt injection code runs
    with preemtion and interrupts disabled. But the
    enable_irq_window() function from SVM may emulate a
    #vmexit. This emulation migth sleep which causes the
    schedule() while atomic() bug.

    These fixes (patches 1 and 2) should also be considered for -stable

    The patches 3 to 8 convert the old printk based debugging for Nested SVM
    to tracepoints. Patch 9 removes the nsvm_printk code. Please review
    and/or consider to apply these changes.



    Changes to v1:

    * Fixed typo on comment in patch
    "KVM: SVM: Notify nested hypervisor of lost event injections"
    * Made the fix for the schedule()-while-atomic bug out of the generic
    code. It touches only SVM code now.
