They had better. Every time you change a core header file, you'd
better check it. And the minimum check is "build as much as you can on
your primary architecture", which is usually something like
'allmodconfig'.

Indeed. I do an 'allmodconfig' build between every single pull I do
(except when traveling - it gets too painful on a laptop), and often
do a couple of other builds too (ie I have my own "machine config"
that I also do).
And yeah, I will complain if that build is not quiet. The standard
kernel build needs to be _clean_, because that's the only way you
notice when new problems happen.
