This test is userspace code, but uses some kernel headers via symlinks,
and mocks other headers, in order to test load_unaligned_zeropad().
Currently the test fails to build with:
In file included from load_unaligned_zeropad.c:26:
word-at-a-time.h:7:10: fatal error: linux/bitops.h: No such file or directory
7 | #include <linux/bitops.h>
This is due to the recent changes to the kernel headers.
Fix it by symlinking the new wordpart.h, and creating an empty stub for
bitops.h which is all that's needed.

This macro is taken from s390, and allows more flexibility in
changing exception table format.
mpe: Put it in ppc_asm.h and only define one version using
stringinfy_in_c(). Add some empty definitions and headers to keep the
selftests happy.
