[PATCH 1/3] nvme: fix the dangerous reference of namespaces list

nvme_remove_namespaces and nvme_remove_invalid_namespaces reference the ctrl->namespaces list w/o holding namespaces_mutext. It is ok to invoke nvme_ns_remove there, but what if there is others. To be safer, reference the ctrl->namespaces list under namespaces_mutext. Signed-off-by: Jianchao

[PATCH] nvme-pci: drain the entered requests after ctrl is shutdown

Currently, we will unquiesce the queues after the controller is shutdown to avoid residual requests to be stuck. In fact, we can do it more cleanly, just wait freeze and drain the queue in nvme_dev_disable and finally leave the queues quiesced. Signed-off-by: Jianchao Wang

[PATCH 5/8] nvme-pci: suspend queues based on online_queues

nvme cq irq is freed based on queue_count. When the sq/cq creation fails, irq will not be setup. free_irq will warn 'Try to free already-free irq'. To fix it, we only increase online_queues when adminq/sq/cq are created and associated irq is setup. Then suspend queues based on online_queues.

[PATCH 10/17] kexec_file: Allow archs to set purgatory load address

For s390 new kernels are loaded to fixed addresses in memory before they are booted. With the current code this is a problem as it assumes the kernel will be loaded to an 'arbitrary' address. In particular, kexec_locate_mem_hole searches for a large enough memory region and sets the load address
