Subject: [PATCH 2.6.27] x86: memtest fix use of reserve_early()
Date: Mon, 13 Oct 2008 10:34:12 +0200	[thread overview]
Message-ID: <20081013103412.6fec375a@buddha> (raw)

Hi all,
    
Wrong usage of 2nd parameter in reserve_early call.
66/75: reserve_early(start_bad, last_bad - start_bad, "BAD RAM");
                                ^^^^^^^^^^^^^^^^^^^^
    
The correct way is to use 'end' address and not 'size'.
As a bonus a fix to the printk format.
