[Linux-ia64] missing exports of __strlen_user(), __strncpy_from_user()?

[Linux-ia64] missing exports of __strlen_user(), __strncpy_from_user()?

[John Kohl]

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,
