From 8b27f2ff7a24f0735c96055e676872f05398d99b Mon Sep 17 00:00:00 2001 From: Nikhil P Rao Date: Wed, 25 May 2011 10:18:41 -0700 Subject: [PATCH] x86: Remove unnecessary check in detect_ht() This patch removes a check that causes incorrect scheduler domain setup (SMP instead of SMT) and bootlog warning messages when cpuid extensions for topology enumeration are not supported and the number of processors reported to the OS is smaller than smp_num_siblings.
