slavio_intctl: avoid structure holes spotted by pahole
Report from pahole on amd64 host:
struct SLAVIO_INTCTLState {
SysBusDevice busdev; /* 0 5648 */
/* --- cacheline 88 boundary (5632 bytes) was 16 bytes ago --- */
uint32_t intregm_pending; /* 5648 4 */
uint32_t intregm_disabled; /* 5652 4 */
uint32_t target_cpu; /* 5656 4 */
/* XXX 4 bytes hole, try to pack */
qemu_irq cpu_irqs[16][16]; /* 5664 2048 */
/* --- cacheline 120 boundary (7680 bytes) was 32 bytes ago --- */
SLAVIO_CPUINTCTLState slaves[16]; /* 7712 384 */
/* --- cacheline 126 boundary (8064 bytes) was 32 bytes ago --- */
/* size: 8096, cachelines: 127 */
/* sum members: 8092, holes: 1, sum holes: 4 */
/* last cacheline: 32 bytes */
}; /* definitions: 1 */
struct SLAVIO_CPUINTCTLState {
uint32_t intreg_pending; /* 0 4 */
/* XXX 4 bytes hole, try to pack */
struct SLAVIO_INTCTLState * master; /* 8 8 */
uint32_t cpu; /* 16 4 */
uint32_t irl_out; /* 20 4 */
/* size: 24, cachelines: 1 */
/* sum members: 20, holes: 1, sum holes: 4 */
/* last cacheline: 24 bytes */
}; /* definitions: 1 */
Fix by rearranging the structures to avoid padding.
