Author: ngie Date: Fri Feb 10 07:38:39 2017 New Revision: 313539 URL: https://svnweb.freebsd.org/changeset/base/313539 Log: MFC r312418,r312422: r312418: Conditionalize hyperv support in gettimeofday(2) based on MK_HYPERV The effect at runtime is negligible as the hyperv timer isn't available except when hyperv is loaded. This is a prerequisite for conditionalizing the header build/install out of the build r312422: Only conditionally add in hyperv support if we're building amd64 This unbreaks the build because the assembly is written for x64.
