So, I think you made some changes between your last CI run and posting?
A ton of platforms (basically anything with EFI_LOADER disabled) fail to
build now because the two "temp" commits at the end of the series are
always enabled. I took those commits out and ran my world build size
check tests and the results are at:
https://gist.github.com/trini/d42bd392463c39766a5f872c190ccf27
And 64bit ARM looks very reasonable, but I wonder if we can improve the
32bit ARM results?
I also did an every commit run for a 32bit ARM board without EFI_LOADER
(which is going to be the case for size constrained systems) and see
that the series isn't bisect'able to start with, so please fix that for
the next go-round. That said:
