From: Nathan Chancellor <nathan@kernel.org>

When building ARCH=i386 allmodconfig, the following warning occurs:

  cc1: all warnings being treated as errors

Use the '%zu' format specifier, as the variable is a 'size_t'.

Hi,

CI execution was interrupted at some point, so that I'm being
overzealous and respinning it. I bet within this weekend we will
have the results.
