Huacai Chen c2e8fbf908 scsi: libsas: align sata_device's rps_resp on a cacheline ... The rps_resp buffer in ata_device is a DMA target, but it isn't explicitly cacheline aligned. Due to this, adjacent fields can be overwritten with stale data from memory on non-coherent architectures. As a result, the kernel is sometimes unable to communicate with an SATA device behind a SAS expander. Fix this by ensuring that the rps_resp buffer is cacheline aligned. This issue is similar to that fixed by Commit 84bda12af3 ("libata: align ap->sector_buf") and Commit 4ee34ea3a1 ("libata: Align ata_device's id on a cacheline").
