While checkpatch is indeed of arguable value, I think it would help a lot not having to bother about the persistent _build_ failures on 32-bit systems. You mentioned the fancy drm CI system above, but they don't run tests and not even test builds on 32-bit targets, which has repeatedly caused (and currently does cause) build failures in drm code when trying to build, say, arm:allmodconfig in linux-next. Most trivial build failures in linux-next (and, yes, sometimes mainline) could be prevented with a simple generic CI.
Yes, definitely. Thanks for bringing that up.

Kisskb can send out email when builds get broken, and when they get fixed again. I receive such emails for the m68k builds.
Like this (yes, one more in DRM; sometimes I wonder if DRM is meant only for 64-bit little-endian platforms with +200 GiB/s memory bandwidth):

The driver is meant for a controller featured in an SoC with a Cortex-A8 ARM CPU and less than a GiB/s memory bandwidth.
And I just sent a fix for that one, thanks for the report.
