Subject: x86: Use SIZE_MAX instead of (long int)-1 for tunable range value
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=905fdc7071638612027739d74d63fc91debb0325;p=thirdparty%2Fglibc.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.

(cherry picked from commit a1b8b06a55c1ee581d5ef860cec214b0c27a66f0)
