Subject: [PATCH v3] sh: Implement __get_user_u64() required for 64-bit get_user()

Hi!

This is version 3 of my patch to implement __get_user_u64() for SH.

I have asked both Yutaka Niibe and Yoshinori Sato to look over my changes and they
both agreed that an entry in __ex_tables for the second access was missing, so I
add the missing ".long 1b+2, 3b\n\t".

The changes should be correct now and will hopefully get a positive review by
the SH maintainers.

Thanks,
Adrian
