Just a remark that I find it a bit odd that that a header that looks
arm-specific is in the generic linux/ directory (already in the kernel,
I know.) Is this for sharing between arm and arm64, maybe?
I don't think arm platforms will use this header. In section 4.1 of SDEI
spec, it says " Both the client and dispatcher of SDEI must execute in
AArch64 state."
So shall we move it to include/standard-headers/asm-arm64/?
Thanks,
