[PATCH 1/8] arch/ppc: Use FIELD_SIZEOF

[Julia Lawall]

From: Julia Lawall <julia at diku.dk>

Robert P.J. Day proposed to use the macro FIELD_SIZEOF in replace of code
that matches its definition.

The modification was made using the following semantic patch
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>

#include <linux/kernel.h>

- (sizeof(((t*)0)->f))
+ FIELD_SIZEOF(t, f)
