Subject: [mmotm][PATCH] fix ia64 build error


Applied after: linux-next.patch

Subject: [PATCH] remove duplicate EXPORT_SYMBOL()
Impact: fix build error

In past, ia64_ksyms.c had EXPORT_SYMBOL(copy_page) in wrong place.

old code was

	#include <asm/uaccess.h>
	EXPORT_SYMBOL(__copy_user);
	EXPORT_SYMBOL(__do_clear_user);
	EXPORT_SYMBOL(__strlen_user);
	EXPORT_SYMBOL(__strncpy_from_user);
	EXPORT_SYMBOL(__strnlen_user);
	EXPORT_SYMBOL(copy_page);

(but actually, copy_page is declared in asm/page.h)

And recently, commit bdc2619ab95d45d434c16d5c216bc6243761f6fb insert
EXPORT_SYMBOL(copy_page) into correct place.

then, duplicate EXPORT_SYMBOL create following build error.

arch/ia64/kernel/ia64_ksyms.c:65: error: redefinition of '__kcrctab_copy_page'
arch/ia64/kernel/ia64_ksyms.c:43: error: previous definition of '__kcrctab_copy_page' was here
