Tests which did not succeed and are blocking,
including tests which could not be run:

    x86/APIC: reduce rounding errors in calculations
    
    Dividing by HZ/10 just to subsequently multiply by HZ again in all uses
    of the respective variable is pretty pointlessly introducing rounding
    (really: truncation) errors. While transforming the respective
    expressions it became apparent that "result" would be left unused except
    for its use as function return value. As the sole caller of the function
    doesn't look at the returned value, simply convert the function to have
    "void" return type.

    x86/time: reduce rounding errors in calculations
    
    Plain (unsigned) integer division simply truncates the results. The
    overall errors are smaller though if we use proper rounding. (Extend
    this to the purely cosmetic aspect of time.c's freq_string(), which
    before this change I've frequently observed to report e.g. NN.999MHz
    HPET clock speeds.)
    
    While adding the rounding logic, also switch to using an unsigned
    constant for the other, original half of bus_cycle's calculation.

    spinlocks: fix placement of preempt_[dis|en]able()
    
    In case Xen ever gains preemption support the spinlock coding's
    placement of preempt_disable() and preempt_enable() should be outside
    of the locked section.

    x86/APIC: adjust types and comments in calibrate_APIC_clock()
    
    First and foremost the comment talking about potential underflow being
    taken care of by using signed long type variables was true only on
    32-bit, which we've not been supporting for quite some time. Drop the
    comment and change all involved types to unsigned. Take the opportunity
    and also replace bus_cycle's fixed width type.
    
    Additionally there's no point using an "arbitrary (but long enough)
    timeout" here. Just use the maximum possible value; Linux does so too,
    just as an additional data point.

    kconfig: expose all{yes,no}config targets
    
    Without having them at least at the xen/Makefile level they're (close
    to?) inaccessible. As I'm uncertain about their utility at the top
    level, I'm leaving it at that for now.

    AMD/IOMMU: fix off-by-one in amd_iommu_get_paging_mode() callers
    
    amd_iommu_get_paging_mode() expects a count, not a "maximum possible"
    value. Prior to b4f042236ae0 dropping the reference, the use of our mis-
    named "max_page" in amd_iommu_domain_init() may have lead to such a
    misunderstanding. In an attempt to avoid such confusion in the future,
    rename the function's parameter and - while at it - convert it to an
    inline function.
    
    Also replace a literal 4 by an expression tying it to a wider use
    constant, just like amd_iommu_quarantine_init() does.
    
    Fixes: ea38867831da ("x86 / iommu: set up a scratch page in the quarantine 
domain")
    Fixes: b4f042236ae0 ("AMD/IOMMU: Cease using a dynamic height for the IOMMU 
pagetables")
