Subject: [PATCH 00/11] address remaining stringop-truncation warnings

From: Arnd Bergmann <arnd@...db.de>

We are close to being able to turn on -Wstringop-truncation
unconditionally instead of only at the 'make W=1' level, these ten
warnings are all that I saw in randconfig testing across compiler versions
on arm, arm64 and x86.

The final patch is only there for reference at the moment, I hope
we can merge the other ones through the subsystem trees first,
as there are no dependencies between them.
