m48t59: avoid structure holes spotted by pahole
Report from pahole on amd64 host: struct M48t59State { uint32_t type; /* 0 4 */ /* XXX 4 bytes hole, try to pack */ qemu_irq IRQ; /* 8 8 */ uint32_t io_base; /* 16 4 */ uint32_t size; /* 20 4 */ time_t time_offset; /* 24 8 */ time_t stop_time; /* 32 8 */ struct tm alarm; /* 40 56 */ /* --- cacheline 1 boundary (64 bytes) was 32 bytes ago --- */ struct QEMUTimer * alrm_timer; /* 96 8 */ struct QEMUTimer * wd_timer; /* 104 8 */ uint8_t lock; /* 112 1 */ /* XXX 1 byte hole, try to pack */ uint16_t addr; /* 114 2 */ /* XXX 4 bytes hole, try to pack */ uint8_t * buffer; /* 120 8 */ /* --- cacheline 2 boundary (128 bytes) --- */ /* size: 128, cachelines: 2 */ /* sum members: 119, holes: 3, sum holes: 9 */ }; /* definitions: 1 */ Fix by rearranging the structure to avoid padding.
