From: venkatesh.pallipadi@intel.com Date: Fri, 19 Dec 2008 21:47:27 +0000 (-0800) Subject: x86: PAT: modify follow_phys to return phys_addr prot and return value X-Git-Tag: v2.6.29-rc1~587^2~4^20~3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d87fe6607c31944f7572f965c1507ae77026c133;p=pandora-kernel.git x86: PAT: modify follow_phys to return phys_addr prot and return value Impact: Changes and globalizes an existing static interface. Follow_phys does similar things as follow_pfnmap_pte. Make a minor change to follow_phys so that it can be used in place of follow_pfnmap_pte. Physical address return value with 0 as error return does not work in follow_phys as the actual physical address 0 mapping may exist in pte.
