From f139cfa7cdccd0b315fad098889897b5fcd389b0 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 31 Jul 2008 12:23:53 +0800 Subject: crypto: tcrypt - Avoid using contiguous pages If tcrypt is to be used as a run-time integrity test, it needs to be more resilient in a hostile environment. For a start allocating 32K of physically contiguous memory is definitely out. This patch teaches it to use separate pages instead.
