From d471bf3ebbabd14f092655485f7562895b22e6b0 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 29 Jun 2018 16:22:13 +0200 Subject: [PATCH] hw/i386: Use the IEC binary prefix definitions It eases code review, unit is explicit. Patch generated using: $ git grep -E '[<>][<>]=? ?[1-5]0' hw/ include/hw/ and modified manually.
