[BUG] timer_migration interface accepts any number as input in2.6.30-git9

[poornima nayak]

Hi

Timer migration interface /proc/sys/kernel/timer_migration in
2.6.30-git9 accepts any numerical value as input.
Steps to reproduce 
1. echo -6666666 > /proc/sys/kernel/timer_migration
2. cat /proc/sys/kernel/timer_migration
-6666666

1. echo 44444444444444444444444444444444444444444444444444444444444 > /proc/sys/kernel/timer_migration
2. cat /proc/sys/kernel/timer_migration
-1357789412

Expected behavior: Should 'echo: write error: Invalid argument' while
setting any value other then 0 & 1

Regards
Poornima
