From 0e6d4986e7940125a04ba8c3aa558f3b248cb9b4 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 16 Oct 2009 17:27:58 +0900 Subject: [PATCH] sh: Make check_pgt_cache() more aggressive while idling. This follows the x86 change and moves check_pgt_cache() up under the !need_resched() tight loop, rather than simply calling in to it when exiting idle.
