[PATCH] xtensa: remove verify_area macros

verify_area() is still alive on xtensa in 2.6.17-rc3-git13 It would be nice
to finally be rid of that function across the board.

- * verify_area determines whether a memory access is allowed.  It's
- * mostly an unnecessary wrapper for access_ok, but we provide it as a
- * duplicate of the verify_area() C inline function below.  See the
- * equivalent C version below for clarity.
- *
- * On error, verify_area branches to a label indicated by parameter
- * <error>.  This implies that the macro falls through to the next
- * instruction on success.
- *
- * Note that we assume success is the common case, and we optimize the
- * branch fall-through case on success.
- *
- * On Entry:
- * 	<aa>	register containing memory address
- * 	<as>	register containing memory size
- * 	<at>	temp register
- * 	<error>	label to branch to on error; implies fall-through
- * 		macro on success
- * On Exit:
- * 	<aa>	preserved
- * 	<as>	preserved
- * 	<at>	destroyed
