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.
