ChangeSet 1.2231.1.50, 2005/03/28 19:30:36-08:00, [EMAIL PROTECTED]
[PATCH] rename FPU_*verify_area to FPU_*access_ok
Since verify_area is going the way of the Dodo soon it seems resonable
to
no longer refer to it in wrapper functions/macros. FPU_verify_area and
FPU_code_verify_area have already been converted to call access_ok so
now
seems a good time to rename them. This patch makes no functional
changes
at all.
