Subject: [PATCH 7/7] arch/sparc/kernel: Use set_cpus_allowed_ptr
From: Julia Lawall <julia@...u.dk>
Use set_cpus_allowed_ptr rather than set_cpus_allowed.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression E1,E2;
@@
- set_cpus_allowed(E1, cpumask_of_cpu(E2))
+ set_cpus_allowed_ptr(E1, cpumask_of(E2))
@@
expression E;
identifier I;
@@
- set_cpus_allowed(E, I)
+ set_cpus_allowed_ptr(E, &I)
// </smpl>
