Subject: [PATCH] arm: add kernel/fork.c function definitions

Add the definitions of arch_release_task_struct,
arch_task_cache_init and arch_dup_task_struct which
are used in kernel/fork.c but defined in various
architecture's <asm/thread_info.h>.

Fixes the following warnings:

kernel/fork.c:160:13: warning: symbol 'arch_release_task_struct' was not declared. Should it be static?
kernel/fork.c:752:20: warning: symbol 'arch_task_cache_init' was not declared. Should it be static?
kernel/fork.c:841:12: warning: symbol 'arch_dup_task_struct' was not declared. Should it be static?
