This patch series fixes up a couple of architecture issues where strscpy wasn't configured correctly (missing on h8300, duplicating local and asm-generic copies on powerpc and tile).
It also adds a use of zero_bytemask() to the final store for strscpy to avoid writing uninitialized data to the destination. However, to make this work we had to add support for zero_bytemask() to the two architectures that didn't have it (alpha and tile), because they were providing their own local copies, but didn't provide the zero_bytemask() that was previously only required when building with CONFIG_DCACHE_WORD_ACCESS.
