Tests which did not succeed and are blocking,
including tests which could not be run:
 build-i386-oldkern            4 xen-build                 fail REGR. vs. 17481

Regressions which are regarded as allowable (not blocking):

    x86/mm/shadow: spurious warning when unmapping xenheap pages.
    Xenheap pages will always have an extra typecount, taken in
    share_xen_page_with_guest(), which doesn't come from a shadow PTE.
    Adjust the warning in sh_remove_all_mappings() to account for it.

    VMX: Always disable SMEP when guest is in non-paging mode
    commit e7dda8ec9fc9020e4f53345cdbb18a2e82e54a65
      VMX: disable SMEP feature when guest is in non-paging mode
    disabled the SMEP bit if a guest VCPU was using HAP and was not
    in paging mode. However I could observe VCPUs getting stuck in
    the trampoline after the following patch in the Linux kernel
    changed the way CR4 gets set up:
      x86, realmode: read cr4 and EFER from kernel for 64-bit trampoline
    The change will set CR4 from already set flags which includes the
    SMEP bit. On bare metal this does not matter as the CPU is in non-
    paging mode at that time. But Xen seems to use the emulated non-
    paging mode regardless of HAP (I verified that on the guests I was
    seeing the issue, HAP was not used).
    Therefor it seems right to unset the SMEP bit for a VCPU that is
    not in paging-mode, regardless of its HAP usage.

commit 5da556675105169807ae2bfe232a2cc4c3f2ae1e

    x86: irq_move_cleanup_interrupt() must ignore legacy vectors
    Since the main loop in the function includes legacy vectors, and since
    vector_irq[] gets set up for legacy vectors regardless of whether those
    get handled through the IO-APIC, it must not do anything on this vector
    range. In fact, we should never get past the move_cleanup_count check
    for IRQs not handled through the IO-APIC. Adding a respective assertion
    woulkd make those iterations more expensive (due to the lock acquire).
    For such an assertion to not have false positives we however ought to
    suppress setting up IRQ2 as an 8259A interrupt (which wasn't correct
    anyway), which is being done here despite the assertion not actually
    getting added.
    Furthermore, there's no point iterating over the vectors past
    LAST_HIPRIORITY_VECTOR, so terminate the loop accordingly.
