From: Pekka Enberg Date: Thu, 5 Mar 2009 12:54:57 +0000 (+0200) Subject: x86: remove unnecessary save_mr() sanity check X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=96083ca11bc85265c7ef9e791a57e3514d8f605a;p=openwrt%2Fstaging%2Fblogic.git x86: remove unnecessary save_mr() sanity check Impact: cleanup The save_mr() function already checks that start_pfn is less than end_pfn so we can remove the unnecessary check which reduces the diff between the 32-bit and the 64-bit versions of init_memory_mapping().
