Subject: x86: Use SIZE_MAX instead of (long int)-1 for tunable range value
X-Git-Tag: glibc-2.34~954
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=a1b8b06a55c1ee581d5ef860cec214b0c27a66f0;p=glibc.git

x86: Use SIZE_MAX instead of (long int)-1 for tunable range value

The tunable types are SIZE_T, so set the ranges to the correct maximum
value, i.e. SIZE_MAX.
