From c812d8f7ad27bd5f1ed1c790eea8527b6f8ff1c7 Mon Sep 17 00:00:00 2001 From: Zhao Jin Date: Sat, 20 Aug 2011 21:24:57 +0800 Subject: [PATCH] x86, mm, trivial: Remove unnecessary get_order() in free_thread_info() Because THREAD_SIZE is defined as PAGE_SIZE << THREAD_ORDER on x86, the call of get_order(THREAD_SIZE) can be replaced with THREAD_ORDER.
