[PATCH 2.4] random poolsize sysctl fix

[Vasily Averin <vvs@sw.ru>]

Hello Marcelo,

SWSoft Linux kernel Team has discovered that your patch 
http://linux.bkbits.net:8080/linux-2.4/gnupatch@41e2c4fetTJmVti-Xxql21xXjfbpag
which should fix a random poolsize sysctl handler integer overflow, is 
wrong.
You have changed a variable definition in function proc_do_poolsize(), 
but you had to fix an another function, poolsize_strategy()
