Stefano Stabellini 7ea11bf376 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.
