Serge Semin f829230dd5 block: sed-opal: kmalloc the cmd/resp buffers ... In accordance with [1] the DMA-able memory buffers must be cacheline-aligned otherwise the cache writing-back and invalidation performed during the mapping may cause the adjacent data being lost. It's specifically required for the DMA-noncoherent platforms [2]. Seeing the opal_dev.{cmd,resp} buffers are implicitly used for DMAs in the NVME and SCSI/SD drivers in framework of the nvme_sec_submit() and sd_sec_submit() methods respectively they must be cacheline-aligned to prevent the denoted problem. One of the option to guarantee that is to kmalloc the buffers [2]. Let's explicitly allocate them then instead of embedding into the opal_dev structure instance. Note this fix was inspired by the commit c94b7f9bab ("nvme-hwmon: kmalloc the NVME SMART log buffer").
