[Qemu-devel] [PATCH] xbzrle: fix compilation on ppc32 |

When compiling the xbzrle code on my ppc32 user space, I hit the following
gcc compiler warning (treated as an error):
cc1: warnings being treated as errors
savevm.c: In function ‘xbzrle_encode_buffer’:
savevm.c:2476: error: overflow in implicit constant conversion
Fix this by making the cast explicit, rather than implicit.
