From f1f7a1ddf38f4261058c604c32c488a0b7af9814 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 16 Jun 2016 17:06:17 +0100 Subject: [PATCH] block/qcow2: Don't use cpu_to_*w() Don't use the cpu_to_*w() functions, which we are trying to deprecate. Instead either just use cpu_to_*() to do the byteswap, or use st*_be_p() if we need to do the store somewhere other than to a variable that's already the correct type.
