LoongArch now provides kernel_fpu_begin() and kernel_fpu_end() that are
used like the x86 counterparts in commit 2b3bd32ea3
("LoongArch:
Provide kernel fpu functions"), so we can enable DC_FP on LoongArch for
supporting more DCN devices.

Choose this option if you want to use the new display engine

calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64)
|
|
architectures built with Clang (all released versions), whereby the stack

frame gets blown up to well over 5k. This would cause an immediate kernel

panic on most architectures. We'll revert this when the following bug report
|

has been resolved: https://github.com/llvm/llvm-project/issues/41896.
