From 24adf12722b4f2800e5b5f0955d57033f0d0c9e5 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Fri, 2 May 2008 21:50:51 -0500 Subject: [PATCH] lguest: avoid using NR_CPUS as a bounds check. NR_CPUS (being a host number) is an arbitrary limit for the Guest. Using the array size directly (which currently happes to be NR_CPUS) is more futureproof.
