From e344b8a16de429ada3d9126f26e2a96d71348356 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 12 Mar 2013 14:06:00 +1100 Subject: savevm: Add VMSTATE_UINT64_EQUAL helpers The savevm code already includes a number of *_EQUAL helpers which act as sanity checks verifying that the configuration of the saved state matches that of the machine we're loading into to work. Variants already exist for 8 bit 16 bit and 32 bit integers, but not 64 bit integers. This patch fills that hole, adding a UINT64 version.
