Subject: [PATCH 18/19] lib/percpu_ida.c: Remove redundant includes

These three #includes seem to be completely redundant: Removing them
yields identical objdump -d output for each of
{allyes,allno,def}config, and neither included file end up in the
generated dependency file through some recursive include. In total,
about 50 lines are eliminated from .percpu.o.cmd.
