FUJITA Tomonori fce5384755 cdrom: revert commit 22a9189 (cdrom: use kmalloced buffers instead of buffers on stack) ... The commit 22a9189fd0 (cdrom: use kmalloced buffers instead of buffers on stack) is introduced to use kmalloced buffers for packet commands to avoid stack corruption on non coherent platforms. SCSI cdrom uses blk_rq_map_kern, which properly avoids DMA on the stack by using the bounce buffers. IDE cdrom also has the mechnism to avoids DMA on the stack. So we don't need this extra complexitiy in cdrom.c, such as allocating just 8 bytes. The lower layers can handle it.
