block: simplify disk shutdown

2022-09-28T09:32:01Z

[ Upstream commit 6f8191fdf41d3a53cc1d63fe2234e812c55a0092 ] Set the queue dying flag and call blk_mq_exit_queue from del_gendisk for all disks that do not have separately allocated queues, and thus remove the need to call blk_cleanup_queue for them. Rename blk_cleanup_disk to blk_mq_destroy_queue to make it clear that this function is intended only for separately allocated blk-mq queues. This saves an extra queue freeze for devices without a separately allocated queue.

nvme-apple: Add initial Apple SoC NVMe driver

2022-05-02T15:24:45Z

Apple SoCs such as the M1 come with an embedded NVMe controller that is not attached to any PCIe bus. Additionally, it doesn't conform to the NVMe specification and requires a bunch of changes to command submission and IOMMU configuration to work.
