commit c227e69 upstream. Commit 73296bc ("procfs: Use generic_file_llseek in /proc/vmcore") broke seeking on /proc/vmcore. This changes it back to use default_llseek in order to restore the original behaviour. The problem with generic_file_llseek is that it only allows seeks up to inode->i_sb->s_maxbytes, which is zero on procfs and some other virtual file systems. We should merge generic_file_llseek and default_llseek some day and clean this up in a proper way, but for 2.6.35/36, reverting vmcore is the safer solution.
