Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-amd64-libvirt-pair 3 host-install/src_host(3) broken REGR. vs. 
105855
 test-amd64-i386-xl            3 host-install(3)        broken REGR. vs. 105855
 test-amd64-i386-libvirt-qemuu-debianhvm-amd64-xsm 3 host-install(3) broken 
REGR. vs. 105855

 test-amd64-amd64-xl-credit2  17 guest-localmigrate/x10   fail REGR. vs. 105855

Regressions which are regarded as allowable (not blocking):

    VMX: fix VMCS race on context-switch paths
    
    When __context_switch() is being bypassed during original context
    switch handling, the vCPU "owning" the VMCS partially loses control of
    it: It will appear non-running to remote CPUs, and hence their attempt
    to pause the owning vCPU will have no effect on it (as it already
    looks to be paused). At the same time the "owning" CPU will re-enable
    interrupts eventually (the lastest when entering the idle loop) and
    hence becomes subject to IPIs from other CPUs requesting access to the
    VMCS. As a result, when __context_switch() finally gets run, the CPU
    may no longer have the VMCS loaded, and hence any accesses to it would
    fail. Hence we may need to re-load the VMCS in vmx_ctxt_switch_from().
    
    For consistency use the new function also in vmx_do_resume(), to
    avoid leaving an open-coded incarnation of it around.

    xen/p2m: Fix p2m_flush_table for non-nested cases
    
    Commit 71bb7304e7a7a35ea6df4b0cedebc35028e4c159 added flushing of
    nested p2m tables whenever the host p2m table changed.  Unfortunately
    in the process, it added a filter to p2m_flush_table() function so
    that the p2m would only be flushed if it was being used as a nested
    p2m.  This meant that the p2m was not being flushed at all for altp2m
    callers.
    
    Only check np2m_base if p2m_class for nested p2m's.
    
    NB that this is not a security issue: The only time this codepath is
    called is in cases where either nestedp2m or altp2m is enabled, and
    neither of them are in security support.

    x86/ept: allow write-combining on !mfn_valid() MMIO mappings again
    
    For some MMIO regions, such as those high above RAM, mfn_valid() will
    return false.
    
    Since the fix for XSA-154 in commit c61a6f74f80e ("x86: enforce
    consistent cachability of MMIO mappings"), guests have no longer been
    able to use PAT to obtain write-combining on such regions because the
    'ignore PAT' bit is set in EPT.
    
    We probably want to err on the side of caution and preserve that
    behaviour for addresses in mmio_ro_ranges, but not for normal MMIO
    mappings. That necessitates a slight refactoring to check mfn_valid()
    later, and let the MMIO case get through to the right code path.
    
    Since we're not bailing out for !mfn_valid() immediately, the range
    checks need to be adjusted to cope Â? simply by masking in the low bits
    to account for 'order' instead of adding, to avoid overflow when the mfn
    is INVALID_MFN (which happens on unmap, since we carefully call this
    function to fill in the EMT even though the PTE won't be valid).
    
    The range checks are also slightly refactored to put only one of them in
    the fast path in the common case. If it doesn't overlap, then it
    *definitely* isn't contained, so we don't need both checks. And if it
    overlaps and is only one page, then it definitely *is* contained.
    
    Finally, add a comment clarifying how that 'return -1' works Â? it isn't
    returning an error and causing the mapping to fail; it relies on
    resolve_misconfig() being able to split the mapping later. So it's
    *only* sane to do it where order>0 and the 'problem' will be solved by
    splitting the large page. Not for blindly returning 'error', which I was
    tempted to do in my first attempt.

    xen: credit2: never consider CPUs outside of our cpupool.
    
    In fact, relying on the mask of what pCPUs belong to
    which Credit2 runqueue is not enough. If we only do that,
    when Credit2 is the boot scheduler, we may ASSERT() or
    panic when moving a pCPU from Pool-0 to another cpupool.
    
    This is because pCPUs outside of any pool are considered
    part of cpupool0. This puts us at risk of crash when those
    same pCPUs are added to another pool and something
    different than the idle domain is found to be running
    on them.
    
    Note that, even if we prevent the above to happen (which
    is the purpose of this patch), this is still pretty bad,
    in fact, when we remove a pCPU from Pool-0:
    - in Credit1, as we do *not* update prv->ncpus and
      prv->credit, which means we're considering the wrong
      total credits when doing accounting;
    - in Credit2, the pCPU remains part of one runqueue,
      and is hence at least considered during load balancing,
      even if no vCPU should really run there.
    
    In Credit1, this "only" causes skewed accounting and
    no crashes because there is a lot of `cpumask_and`ing
    going on with the cpumask of the domains' cpupool
    (which, BTW, comes at a price).
    
    A quick and not to involved (and easily backportable)
    solution for Credit2, is to do exactly the same.
