Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-armhf-armhf-xl-arndale 15 guest-start/debian.repeat fail REGR. vs. 101076
 test-armhf-armhf-libvirt-qcow2  9 debian-di-install      fail REGR. vs. 101076

Regressions which are regarded as allowable (not blocking):
 test-armhf-armhf-xl-rtds     15 guest-start/debian.repeat    fail  like 101076

commit 506182e00772ece038ca5207c54dfab3de57adef
Author: Emanuel Czirai <icanrealizeum@xxxxxxxxx>

    x86/AMD: apply erratum 665 workaround
    
    AMD F12h machines have an erratum which can cause DIV/IDIV to behave
    unpredictably. The workaround is to set MSRC001_1029[31] but sometimes
    there is no BIOS update containing that workaround so let's do it
    ourselves unconditionally. It is simple enough.

    x86emul: correct loading of %ss
    
    - Instead of #NP, #SS needs to be raised for non-present descriptors.
    - Loading a null selector is fine in 64-bit mode at CPL != 3, as long
      as RPL == CPL.
    - Don't lose the low two selector bits on null selector loads (also
      applies to %ds, %es, %fs, %gs, and LDTR).
    
    Since we need CPL earlier now, also switch to using get_cpl() (instead
    of open coding it).

    x86/Intel: hide CPUID faulting capability from guests
    
    We don't currently emulate it, so guests should not be misguided to
    believe they can (try to) use it.
    
    For now, simply return zero to guests for platform MSR reads, and only
    accept (by discarding) writes of zero. If ever there will be bits we
    can safely expose to guests, let's handle them by white listing.
    
    (As a side note - according to SDM version 059 bit 31 is reserved on
    all known families.)

    xen: credit2: properly schedule migration of a running vcpu.
    
    If wanting to migrate a vcpu that is actually running,
    we need to ask the scheduler to chime in as soon as
    possible, to have the vcpu itself stopped and actually
    moved.
    
    Make sure this happens by, after setting all the relevant
    flags, raising the scheduler softirq.

    xen: credit1: fix mask to be used for tickling in Credit1
    
    If there are idle pcpus inside the waking vcpu's
    soft-affinity mask, we should really tickle one
    of them (this is one of the purposes of the
    __runq_tickle() function itself!), not just
    any idle pcpu.
    
    The issue has been introduced in 02ea5031825d
    ("credit1: properly deal with pCPUs not in any cpupool"),
    where the usage of idle_mask is changed, without
    updating the bottom of the function, where it
    is also referenced.

    x86/domctl: Fix migration of guests which are not using xsave
    
    c/s da62246e "x86/xsaves: enable xsaves/xrstors/xsavec in xen" broke 
migration
    of PV guests which were not using xsave.
    
    In such a case, compress_xsave_states() gets passed a zero length buffer.  
The
    first thing it tries to do is ASSERT() on user-provided data, if it hadn't
    already wandered off the end of the buffer to do so.
    
    Perform more verification of the input buffer before passing it to
    compress_xsave_states().  This involves making xsave_area_compressed() 
public.
    
    Similar problems exist on the HVM side, so make equivalent adjustments 
there.
    This doesn't manifest in general, as hvm_save_cpu_xsave_states() elides the
    entire record if xsave isn't used, but is a problem if a caller were to
    construct an xsave record manually.

    x86/domctl: Fix TOCTOU race with the use of XEN_DOMCTL_getvcpuextstate
    
    A toolstack must call XEN_DOMCTL_getvcpuextstate twice; first to find the 
size
    of the buffer to use, and a second time to get the actual content.
    
    The reported size was based on v->arch.xcr0_accum, but a guest which extends
    its xcr0_accum between the two hypercalls will cause the toolstack to fail 
the
    evc->size != size check, as the provided buffer is now too small.  This 
causes
    a hard error during the final phase of migration.
    
    Instead, return a size based on xfeature_mask, which is the maximum size Xen
    will ever permit.  The hypercall must now tolerate a toolstack-provided 
buffer
    which is overly large (for the case where a guest isn't using all available
    xsave states), and should write back how much data was actually written into
    the buffer.
    
    As the query for size now has no dependence on vcpu state, the vcpu_pause()
    can be omitted for a small performance improvement.
