From 8360ee2f74bda2b794bdf4e23ab19d8b4e93807f Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 21 Nov 2011 12:10:19 +0100 Subject: x86, AMD: Correct align_va_addr documentation Commit dfb09f9b7ab0 ("x86, amd: Avoid cache aliasing penalties on AMD family 15h") introduced a kernel command line parameter called 'align_va_addr' which still refers to arguments used in an earlier version of the patch and which got changed without updating the documentation.
