missing exports of __strlen_user(), __strncpy_from_user()?

i386 kernels export strnlen_user() and strncpy_from_user(); the former is referenced by the macro for strlen_user().

ia64 does not export either __strlen_user() or __strncpy_from_user() (referenced by strlen_user() and strncpy_from_user() macros functions). We need these symbols to implement some code in our kernel module (ClearCase MVFS).

I presume this is just an oversight, and they should be added to arch/ia64/kernel/ia64_ksyms.c? I'd suggest adding these, as similar to exported symbols in i386, to make copy_{from,to}_user(), strncpy_from_user(), and clear_user() usable by modules.

EXPORT_SYMBOL(__strncpy_from_user);
EXPORT_SYMBOL(__do_clear_user);
EXPORT_SYMBOL(__strlen_user);
EXPORT_SYMBOL(__strnlen_user);
EXPORT_SYMBOL(__copy_user);

__copy_user and __do_clear_user were already in the current kernel sources but I added the other three now.

Thanks,
