From f318f7db00f4968d934b4ccb8e3fc0b21f419046 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Mon, 1 Sep 2014 16:15:52 -0500 Subject: ia64: sn_nodepda cannot be assigned to after this_cpu conversion. Use __this_cpu_write. There must be an explit statement to modify the percpu variable after the conversion of the sn_nodpda macro to use this_cpu_read.
