Cleancache frontend from kernel 3.7
sparc32: add ucmpdi2

commit de36e66d5fa52bc6e2dacd95c701a1762b5308a7 upstream.

Based on copy from microblaze add ucmpdi2 implementation.
This fixes build of niu driver which failed with:

drivers/built-in.o: In function `niu_get_nfc':
niu.c:(.text+0x91494): undefined reference to `__ucmpdi2'

This driver will never be used on a sparc32 system,
but patch added to fix build breakage with all*config builds.

sparc32: Add ucmpdi2.o to obj-y instead of lib-y.

commit 74c7b28953d4eaa6a479c187aeafcfc0280da5e8 upstream.

Otherwise if no references exist in the static kernel image,
we won't export the symbol properly to modules.
