Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-amd64-xl-qemuu-win7-amd64  9 windows-install  fail REGR. vs. 106412
 test-armhf-armhf-libvirt-raw  9 debian-di-install        fail REGR. vs. 106412

Regressions which are regarded as allowable (not blocking):
 test-amd64-amd64-xl-qemut-win7-amd64 16 guest-stop            fail like 106412
 test-amd64-i386-xl-qemut-win7-amd64 16 guest-stop             fail like 106412
 test-amd64-i386-xl-qemuu-win7-amd64 16 guest-stop             fail like 106412

    x86/cpuid: Fix booting on AMD Phenom 6-core platform
    
    c/s 5cecf60f4 "x86/cpuid: Handle leaf 0x1 in guest_cpuid()" causes Linux 
4.10
    to crash during boot.
    
    It turns out to be because of the reported apic_id, which was altered to be
    more consistent across guests.  Revert back to the previous behaviour, by
    limiting the apic_id adjustment to HVM guests only.  Whomever gets to fixes
    topology representation is going to have a lot of fun with non-power-of-2 
AMD
    boxes.

    xen/arm: introduce vwfi parameter
    
    Introduce new Xen command line parameter called "vwfi", which stands for
    virtual wfi. The default is "trap": Xen traps guest wfi and wfe
    instructions. In the case of wfi, Xen calls vcpu_block on the guest
    vcpu; in the case of guest wfe, Xen calls vcpu_yield on the guest vcpu.
    The behavior can be changed by setting vwfi to "native", in that case
    Xen doesn't trap neither wfi nor wfe, running them in guest context.
    
    The result is strong reduction in irq latency (from 5000ns to 2000ns,
    measured using https://github.com/edgarigl/tbm, the physical timer, and
    1 pcpu dedicated to 1 vcpu). The downside is that the scheduler thinks
    that the guest is busy when actually is sleeping, leading to suboptimal
    scheduling decisions.

    x86/SVM: correct boot time cpu_data[] handling
    
    start_svm() already runs after cpu_data[] was set up, so it shouldn't
    modify it anymore (at least not directly). Constify the involved
    pointers.
    
    Furthermore LMSLE feature detection was broken by 566ddbe833 ("x86:
    Fail CPU bringup cleanly if it cannot initialise HVM"), as Andrew
    Cooper has pointed out: c couldn't possibly equal &boot_cpu_data
    anymore. (But since it's unsafe migration-wise for some more time,
    suppress the feature actually being enabled for us.)

    VMX: properly handle pi when all the assigned devices are removed
    
    This patch handles some corner cases when the last assigned device
    is removed from the domain. In this case we should carefully handle
    pi descriptor and the per-cpu blocking list, to make sure:
    - all the PI descriptor are in the right state when next time a
    devices is assigned to the domain again.
    - No remaining vcpus of the domain in the per-cpu blocking list.
    
    Here we call vmx_pi_unblock_vcpu() to remove the vCPU from the blocking list
    if it is on the list. However, this could happen when vmx_vcpu_block() is
    being called, hence we might incorrectly add the vCPU to the blocking list
    while the last devcie is detached from the domain. Consider that the 
situation
    can only occur when detaching the last device from the domain and it is not
    a frequent operation, so we use domain_pause before that, which is 
considered
    as an clean and maintainable solution for the situation.

of
    X86EMUL_EXCEPTION and ctxt->event_pending.

    Issues identified which I am purposefully not fixing in this patch:
    
    (I will try to get around to them, but probably not in the 4.9 timeframe, at
    this point.)
    
     * hvm_set_cr3() doesn't handle bad 32bit PAE PDPTRs properly, as it doesn't
       actually have a path which raises #GP.
     * There is a lot of redundancy in our HVM CR setting routines, but not 
enough
       to trivially dedup at this point.
     * Both nested VT-x and SVM are liable raise #GP with L1, rather than 
failing
       the virtual vmentry/vmexit.  This is not a change in behaviour, but is 
far
       more obvious now.
     * The hvm_do_resume() path for vm_event processing has the same bug as the
       MSR side, where exceptions are raised after %rip has moved forwards.  
This
       is also not a change in behaviour.

    x86/kconfig: Introduce CONFIG_PV and CONFIG_HVM
    
    Making PV and HVM guests individually compilable is useful as a reduction in

    Introduce CONFIG_PV and CONFIG_HVM, although there is a lot of work to do
    until either can actually be disabled.
