[PATCH] cpuset: remove function attribute const

[Benoit Boissinot <benoit.boissinot@ens-lyon.org>]

gcc-4 warns with 
include/linux/cpuset.h:21: warning: type qualifiers ignored on function
return type

cpuset_cpus_allowed is declared with const
extern const cpumask_t cpuset_cpus_allowed(const struct task_struct *p);

First const should be __attribute__((const)), but the gcc manual
explains that:

"Note that a function that has pointer arguments and examines the data
pointed to must not be declared const. Likewise, a function that calls a
non-const function usually must not be const. It does not make sense for
a const function to return void."

The following patch remove const from the function declaration.
