Slapping __percpu_qual into the next available header is sloppy at best. It's required by __percpu which is defined in compiler_types.h and that is meant to be included without requiring a boatload of other headers so that a struct or function declaration can contain a __percpu qualifier w/o further prerequisites. This implicit dependency on linux/percpu.h makes that impossible and causes a major problem when trying to separate headers. Create asm/percpu_types.h and move it there. Include that from compiler_types.h and the whole recursion problem goes away. Fix up UM so it uses the generic header and includes it in the UM_HOST build, which pulls in compiler_types.h. The USER_CFLAGS fix was suggested by Richard.
