From: Tejun Heo Date: Mon, 2 May 2011 12:18:53 +0000 (+0200) Subject: x86, NUMA: Remove long 64bit assumption from numa.c X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=38f3e1ca24cc3ec416855e02676f91c898a8a262;p=openwrt%2Fstaging%2Fblogic.git x86, NUMA: Remove long 64bit assumption from numa.c Code moved from numa_64.c has assumption that long is 64bit in several places. This patch removes the assumption by using {s|u}64_t explicity, using PFN_PHYS() for page number -> addr conversions and adjusting printf formats.
