[PATCH][2.5.74] use task_cpu() not ->thread_info->cpu in sched.c

[PATCH][2.5.74] use task_cpu() not ->thread_info->cpu in sched.c

[Mikael Pettersson]

Linus,

This patch fixes two p->thread_info->cpu occurrences in kernel/sched.c
to use the task_cpu(p) macro instead, which is optimised on UP.
Although one of the occurrences is under #ifdef CONFIG_SMP, it's bad
style to use the raw non-optimisable form in non-arch code. Please apply.
