charset="utf-8" RISC-V wants to introduce a full build of Xen without using the legacy definitions. PPC64 has the most minimal full build of Xen right now, so ma= ke it compile without the legacy definitions. Mostly this is just including xen/sections.h in a variety of common files. = In a couple of cases, we can drop an inclusion of {xen,asm}/cache.h, but almost all files get the definitions transitively. No functional change.
