mem_class: fix bug
When I build and boot -next on fedora 10, I can not login anymore.
When I input the user name and password, the system does not output
any message and requires user to input the user name and password
again and again.
I find the patch which caused this problem with "GIT BISECT" command.
And the patch is
commit 7c4b7daa1878972ed0137c95f23569124bd6e2b1
"mem_class: use minor as index instead of searching the array".
Though I don't know the real reason why user could not login, I
confirmed the patch I made as following could resolve the problem on
fedora 10.
