From 8cb2a7c1e95e472b5ad8cbde4d5c7bb65c532603 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Tue, 5 Feb 2008 22:26:01 +0000 Subject: [PATCH] stop c_p_a corrupting the pds When change_page_attr splits a large page on x86_32 (without PAE), it is currently corrupting every process's page directory: fix that by removing the thinko which passes down a physical instead of a virtual address.
