Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-amd64-xl-qemuu-ovmf-amd64 9 debian-hvm-install fail REGR. vs. 62702
 test-amd64-i386-xl-qemuu-ovmf-amd64  9 debian-hvm-install fail REGR. vs. 62702

Tests which are failing intermittently (not blocking):
 test-amd64-i386-xl-qemuu-winxpsp3-vcpus1 15 guest-localmigrate/x10 fail in 
77292 pass in 77478
 test-amd64-i386-xl-qemuu-win7-amd64 13 guest-localmigrate   fail pass in 77292

Regressions which are regarded as allowable (not blocking):
 test-amd64-i386-xl-qemuu-win7-amd64 16 guest-stop     fail in 77292 like 62702

Tests which did not succeed, but are not blocking:
 test-amd64-amd64-qemuu-nested-intel 16 debian-hvm-install/l1/l2 fail never pass

commit 2264b0c66075cc34c252a1386f019f8be6240890

    xenfb: avoid reading twice the same fields from the shared page
    
    Reading twice the same field could give the guest an attack of
    opportunity. In the case of event->type, gcc could compile the switch
    statement into a jump table, effectively ending up reading the type
    field multiple times.
    
    This is part of XSA-155.

commit 75421c82154542e6855bbb98e6cccaacb4b8904c
Author: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>
Date:   Fri Dec 18 15:44:58 2015 +0000

    xen/blkif: Avoid double access to src->nr_segments
    
    src is stored in shared memory and src->nr_segments is dereferenced
    twice at the end of the function.  If a compiler decides to compile this
    into two separate memory accesses then the size limitation could be
    bypassed.
    
    Fix it by removing the double access to src->nr_segments.
    
    This is part of XSA-155.
