commit 2264b0c66075cc34c252a1386f019f8be6240890
Author: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>

    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.
