From 0c83ef40d59812f2e58edac2297edb71c25f5478 Mon Sep 17 00:00:00 2001 From: Andrew Cooper Date: Mon, 9 Sep 2019 16:53:28 +0100 Subject: [PATCH] x86/cpuid: Fix build with CentOS 6 following c/s 7479151106 GCC of a CentOS 6 vintage complains: cpuid.c: In function 'parse_xen_cpuid': cpuid.c:32: error: 'mid' may be used uninitialized in this function This can't occur in practice because the while() loop is guarenteed to be entered, but initialise mid to work around the issues.
