This reduces the 'count' size in the common support structure to 32-bits so that it matches up with what oprofile is expecting. The SH7750 code was using a nasty oprofilefs hack to expose the 48-bit counter, although no other implementations were. Now that the offending driver has been killed off, it's possible to restore some semblance of sanity. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
