sun4m_iommu: avoid structure holes spotted by pahole
Report from pahole on amd64 host: struct IOMMUState { SysBusDevice busdev; /* 0 5648 */ /* --- cacheline 88 boundary (5632 bytes) was 16 bytes ago --- */ uint32_t regs[4096]; /* 5648 16384 */ /* --- cacheline 344 boundary (22016 bytes) was 16 bytes ago --- */ target_phys_addr_t iostart; /* 22032 8 */ uint32_t version; /* 22040 4 */ /* XXX 4 bytes hole, try to pack */ qemu_irq irq; /* 22048 8 */ /* size: 22056, cachelines: 345 */ /* sum members: 22052, holes: 1, sum holes: 4 */ /* last cacheline: 40 bytes */ }; /* definitions: 1 */ Fix by rearranging the structure to avoid padding.
