accel/tcg/ files requires the following definitions: - TARGET_LONG_BITS - TARGET_PAGE_BITS - TARGET_PHYS_ADDR_SPACE_BITS - TCG_GUEST_DEFAULT_MO The first 3 are defined in "cpu-param.h". The last one in "cpu.h", with a bunch of definitions irrelevant for TCG. By moving the TCG_GUEST_DEFAULT_MO definition to "cpu-param.h", we can simplify various accel/tcg includes.
