From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] x86: Fix compile issues with rh_check_supported()
Upstream status: RHEL only
The function rh_check_supported is a RHEL function to limit the
platforms RHEL does not want to support.
To avoid imposing this requirement on Fedora, the function was
wrapped with CONFIG_RHEL_DIFFERENCES so Fedora can disable this.
However, this has a few compile warnings that need to be cleaned up
when disabled.
Move CONFIG_RHEL_DIFFERENCES to include the functions themselves
instead of the call. As the unused functions created warnings.
V2: modified stub definition
