I am totally confused, you mentioned 'general kernel do_install', I

the fix upstream in the mainline kernel', how could that happen?
We are discussing about the solution to 'fix the compile warning to
error' stuff that triggered by the '-I/usr/include/slang', right?
Yes.
We do not necessarily have to change recipe to fix it since the issue
is not introduced by the recipe, the hard coded '-I/usr/include/slang'
in the Makefile cause the issue, we can fix the root cause by kernel
patch(other than just comment the line out). I see your previous patch
to kernel, by comment out the '-I/usr/include/slang' line in the
Makefile, is the same behavior, but we won't have the change(comment
out -I.. in Makefile) upstream to mainline, right?
I am suggesting that firstly, someone send a patch to the mainline
kernel which changes -I/usr/include/slang to -I=/usr/include/slang in
that Makefile.
Secondly, I'm suggesting that we add a line to kernel_do_install() in
kernel.bbclass which does a sed on the Makefile as installed into
$kerneldir which changes -I/usr/include/slang to -I=/usr/include/slang.
We can then drop the patch I added to the linux-yocto kernels.
This is all that should be needed, it should fix all the issues people
have reported in a way that is acceptable to everyone.
This is what I was shooting for as well, the oe-core fix is separate
from the upstream kernel fix. We'll fix our builds first, and then
work for a solution in perf upstream.
My only requirement was that our sed fix still work when kernels start
appearing with it fixed upstream .. something that shouldn't be hard
to do.
