Looking at the history behind include/linux/compiler-intel.h, the last
time I see a change that actually references building a kernel with icc
was 503cf95c061a ("x86, build, icc: Remove uninitialized_var() from
compiler-intel.h"), all the way back in 2013. Since then, there do not
appear to be any meaningful changes; every change is basically doing
something for clang or gcc and not wanting to leave icc behind. It might
be worth considering tearing it out.

Cheers,
Nathan
