Subject: [PATCH 5/7] arch/powerpc/kernel: Use set_cpus_allowed_ptr
Date: Fri, 26 Mar 2010 23:03:29 +0100 (CET)	[thread overview]
Message-ID: <Pine.LNX.4.64.1003262303080.6480@ask.diku.dk> (raw)

From: Julia Lawall <julia@diku.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>
