Alex, do you know why the AMDGPU driver uses a different stack alignment (16B) than the rest of the x86 kernel? (see arch/x86/Makefile which uses 8B stack alignment).
Not sure. Maybe Harry can comment. I think it was added for the floating point stuff. Not sure if it's strictly required or not.
Can you find out for me please who knows more about this and setup a chat with all of us? (I don't want to deride this patch's review thread, so let's start a new thread once we know more) We're facing some interesting runtime issues when built with Clang.
