Title
scsi: qla2xxx: Use raw_smp_processor_id() instead of smp_processor_id()
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Use raw_smp_processor_id() instead of smp_processor_id()
The following call trace was observed:
localhost kernel: nvme nvme0: NVME-FC{0}: controller connect complete
localhost kernel: BUG: using smp_processor_id() in preemptible [00000000] code: kworker/u129:4/75092

localhost kernel: caller is qla_nvme_post_cmd+0x216/0x1380 [qla2xxx]
localhost kernel: CPU: 6 PID: 75092 Comm: kworker/u129:4 Kdump: loaded Tainted: G B W OE --------- --- 5.14.0-70.22.1.el9_0.x86_64+debug #1
localhost kernel: Hardware name: HPE ProLiant XL420 Gen10/ProLiant XL420 Gen10, BIOS U39 01/13/2022
localhost kernel: Workqueue: nvme-wq nvme_async_event_work [nvme_core]
localhost kernel: Call Trace:

localhost kernel: check_preemption_disabled+0xc8/0xd0
localhost kernel: qla_nvme_post_cmd+0x216/0x1380 [qla2xxx]
Use raw_smp_processor_id() instead of smp_processor_id().
Also use queue_work() across the driver instead of queue_work_on() thus
avoiding usage of smp_processor_id() when CONFIG_DEBUG_PREEMPT is enabled.
