Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-amd64-xl-qemuu-ws16-amd64 17 guest-stop       fail REGR. vs. 115226
 test-amd64-i386-xl-qemuu-ws16-amd64 16 guest-localmigrate/x10 fail in 116223 
REGR. vs. 115226

Tests which are failing intermittently (not blocking):
 test-amd64-i386-libvirt-qcow2 15 guest-saverestore.2 fail in 116223 pass in 
116245
 test-amd64-i386-xl-qemuu-winxpsp3-vcpus1 16 guest-localmigrate/x10 fail in 
116223 pass in 116245

 test-amd64-i386-xl-qemuu-ws16-amd64 14 guest-localmigrate  fail pass in 116223

Regressions which are regarded as allowable (not blocking):
 test-amd64-i386-xl-qemuu-win7-amd64 17 guest-stop        fail REGR. vs. 115226
 test-amd64-i386-xl-qemut-win7-amd64 17 guest-stop        fail REGR. vs. 115226

    x86/shadow: correct SH_LINEAR mapping detection in sh_guess_wrmap()
    
    The fix for XSA-243 / CVE-2017-15592 (c/s bf2b4eadcf379) introduced a change
    in behaviour for sh_guest_wrmap(), where it had to cope with no shadow 
linear
    mapping being present.
    
    As the name suggests, guest_vtable is a mapping of the guests pagetable, not
    Xen's pagetable, meaning that it isn't the pagetable we need to check for 
the
    shadow linear slot in.
    
    The practical upshot is that a shadow HVM vcpu which switches into 4-level
    paging mode, with an L4 pagetable that contains a mapping which aliases 
Xen's
    SH_LINEAR_PT_VIRT_START will fool the safety check for whether a 
SHADOW_LINEAR
    mapping is present.  As the check passes (when it should have failed), Xen
    subsequently falls over the missing mapping with a pagefault such as:
    
        (XEN) Pagetable walk from ffff8140a0503880:
        (XEN)  L4[0x102] = 000000046c218063 ffffffffffffffff
        (XEN)  L3[0x102] = 000000046c218063 ffffffffffffffff
        (XEN)  L2[0x102] = 000000046c218063 ffffffffffffffff
        (XEN)  L1[0x103] = 0000000000000000 ffffffffffffffff
    
    This is part of XSA-243.

    x86: don't wrongly trigger linear page table assertion
    
    _put_page_type() may do multiple iterations until its cmpxchg()
    succeeds. It invokes set_tlbflush_timestamp() on the first
    iteration, however. Code inside the function takes care of this, but
    - the assertion in _put_final_page_type() would trigger on the second
      iteration if time stamps in a debug build are permitted to be
      sufficiently much wider than the default 6 bits (see WRAP_MASK in
      flushtlb.c),
    - it returning -EINTR (for a continuation to be scheduled) would leave
      the page inconsistent state (until the re-invocation completes).
    Make the set_tlbflush_timestamp() invocation conditional, bypassing it
    (for now) only in the case we really can't tolerate the stamp to be
    stored.
    
    This is part of XSA-240.

    x86/mm: Make PV linear pagetables optional
    
    Allowing pagetables to point to other pagetables of the same level
    (often called 'linear pagetables') has been included in Xen since its
    inception; but recently it has been the source of a number of subtle
    reference-counting bugs.
    
    It is not used by Linux or MiniOS; but it is used by NetBSD and Novell
    Netware.  There are significant numbers of people who are never going
    to use the feature, along with significant numbers who need the
    feature.
