Subject: x86/platform/uv: When searching for minimums, start at INT_MAX not
99999
Git-commit: 35bd896ccc2fa8dfb20df705a44e9d26665f1085
Patch-mainline: 6.5-rc1
References: bsc#1212256 jsc#PED-4718
Using a starting value of INT_MAX rather than 999999 or 99999 means
this algorithm won't fail should the numbers being compared ever
exceed this value.
