[PATCH] percpu: cast away printk format warning
From: Mike Frysinger
Date: Tue Mar 22 2011 - 16:39:24 EST
On 32-bit systems which don't happen to implicitly define or cast
VMALLOC_START and/or VMALLOC_END to long in their arch headers, the
printk in the percpu code will cause a warning to be emitted:
mm/percpu.c: In function 'pcpu_embed_first_chunk':
mm/percpu.c:1648: warning: format '%lx' expects type 'long unsigned int',
but argument 3 has type 'unsigned int'
So add an explicit cast to unsigned long here.
