From: Christoph Lameter Date: Wed, 27 Aug 2014 00:12:21 +0000 (-0500) Subject: percpu: Resolve ambiguities in __get_cpu_var/cpumask_var_t X-Git-Tag: fixes-against-v3.18-rc2~65^2~3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4ba2968420fa9d0604b6a6a5c61bfa8d0fa84ae0;p=pandora-kernel.git percpu: Resolve ambiguities in __get_cpu_var/cpumask_var_t __get_cpu_var can paper over differences in the definitions of cpumask_var_t and either use the address of the cpumask variable directly or perform a fetch of the address of the struct cpumask allocated elsewhere. This is important particularly when using per cpu cpumask_var_t declarations because in one case we have an offset into a per cpu area to handle and in the other case we need to fetch a pointer from the offset. This patch introduces a new macro this_cpu_cpumask_var_ptr() that is defined where cpumask_var_t is defined and performs the proper actions. All use cases where __get_cpu_var is used with cpumask_var_t are converted to the use of this_cpu_cpumask_var_ptr().
