Subject[PATCH 2.5.31] Remove FIXME from kernel/sysctl.c
Remove a "FIXME" from kernel/sysctl.c:do_rw_proc().  The proc_handler
typedef now takes a loff_t * parameter that points to the current possion
in the file. proc_handler()'s now read and change this value instead of
f_pos. This mirrors work done in vfs_read() and vfs_write().
