From 8462e201756dd3bbe7e542106fc6fd6fe059cee2 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Tue, 19 Apr 2005 13:29:20 -0700 Subject: [PATCH] [PATCH] freepgt: sys_mincore ignore FIRST_USER_PGD_NR Remove use of FIRST_USER_PGD_NR from sys_mincore: it's inconsistent (no other syscall refers to it), unnecessary (sys_mincore loops over vmas further down) and incorrect (misses user addresses in ARM's first pgd).
