[Xen-devel] [PATCH 1/1] Compiler Warning Fix

["Anthony Boorsma" <Anthony.Boorsma@xxxxxxxxxxxxxxx>]

This patch fixes a compiler warning in the file xc_core.c. This fix is needed because warnings are treated as errors with the new gcc in Ubuntu 9.10.

 

The fix was also included in a previous submission “[Xen-devel] [PATCH 1/1] Xen ARINC653 scheduler” and is now being resubmitted as a separate patch.
