Subject: 2 small patches

Here are two small patches.

The first one remove a profiler_mark that has been forgotten in one of
the
last update in the tx1.c video driver.

The second is a small speed up in the neo-geo driver which gives a 0.5%
speed up on my machine.
    - replace a loop with an equivalent memset
    - remove a useless parameter I forgot to remove in a previous patch

Hope this help.

Best regards,

CJ
