Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-amd64-xl-qemuu-debianhvm-amd64 15 guest-localmigrate/x10 fail REGR. 
vs. 100779
 test-amd64-amd64-xl-qemut-debianhvm-amd64-xsm 15 guest-localmigrate/x10 fail 
REGR. vs. 100779

Regressions which are regarded as allowable (not blocking):

commit 26352b6344ce5d5a2ee78e56ae631e156fbdce7f

    x86/shadow: Avoid overflowing sh_ctxt->seg_reg[]
    
    hvm_get_seg_reg() does not perform a range check on its input segment, calls
    hvm_get_segment_register() and writes straight into sh_ctxt->seg_reg[].
    
    x86_seg_none is outside the bounds of sh_ctxt->seg_reg[], and will hit a 
BUG()
    in {vmx,svm}_get_segment_register().
    
    HVM guests running with shadow paging can end up performing a virtual to
    linear translation with x86_seg_none.  This is used for addresses which are
    already linear.  However, none of this is a legitimate pagetable update, so
    fail the emulation in such a case.
    
    This is XSA-187 / CVE-2016-7094.

    x86/emulate: Correct boundary interactions of emulated instructions
    
    This reverts most of c/s 0640ffb6 "x86emul: fix rIP handling".
    
    Experimentally, in long mode processors will execute an instruction stream
    which crosses the 64bit -1 -> 0 virtual boundary, whether the instruction
    boundary is aligned on the virtual boundary, or is misaligned.
    
    In compatibility mode, Intel processors will execute an instruction stream
    which crosses the 32bit -1 -> 0 virtual boundary, while AMD processors 
raise a
    segmentation fault.  Xen's segmentation behaviour matches AMD.
    
    For 16bit code, hardware does not ever truncated %ip.  %eip is always used 
and
    behaves normally as a 32bit register, including in 16bit protected mode
    segments, as well as in Real and Unreal mode.
    
    This is XSA-186 / CVE-2016-7093.

    x86/32on64: don't allow recursive page tables from L3
    
    L3 entries are special in PAE mode, and hence can't reasonably be used
    for setting up recursive (and hence linear) page table mappings. Since
    abuse is possible when the guest in fact gets run on 4-level page
    tables, this needs to be excluded explicitly.
    
    This is XSA-185 / CVE-2016-7092.
