From 0c82d83cb09a1c9fd4d24d32064ce827709c104b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 27 Feb 2008 13:44:59 +0100 Subject: [PATCH] [ARM] Fix freeing of page tables for ARM in free_pgd_slow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since 2f569af (CONFIG_HIGHPTE vs. sub-page page tables.) pte_free() calls pte_lock_deinit() and dec_zone_page_state(). So free_pgd_slow must not call the latter two when calling the first.
