[Qemu-devel] [PATCH 1/3] monitor: avoid clang shifting negative signed warning

[Stefan Hajnoczi]

clang 3.7.0 on x86_64 warns about the following:

  target-i386/monitor.c:38:22: warning: shifting a negative signed value is 
undefined [-Wshift-negative-value]
        addr |= -1LL << 48;
                ~~~~ ^
