[PATCH 1/2] ia64: macro-ize ia64_done_with_exception in asm/uaccess.h

[Paul Gortmaker <paul.gortmaker@windriver.com>]

Most of the other C content in this file is already implemented
in macro form.  Doing the same for this function will allow us
to get rid of the duplicated search_exception_tables prototype.
We will bring it in as required via <linux/extable.h> inclusion.
