Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (ufs, lpfc, fnic, qla2xx, mpi3mr).

  The major core change is the renaming of the slave_ methods plus a bit
  of constification. The rest are minor updates and fixes"

scsi: replace blk_mq_pci_map_queues with blk_mq_map_hw_queues

2024-12-23T15:17:23+00:00

Replace all users of blk_mq_pci_map_queues with the more generic
blk_mq_map_hw_queues. This in preparation to retire
blk_mq_pci_map_queues.

scsi: Constify struct pci_device_id

2024-12-10T02:59:52+00:00

'struct pci_device_id' is not modified in these drivers.

Constifying this structure moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  70237	   9137	    320	  79694	  1374e	drivers/scsi/3w-9xxx.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  70461	   8913	    320	  79694	  1374e	drivers/scsi/3w-9xxx.o

scsi: Eliminate scsi_register() and scsi_unregister() usage & docs

2024-12-10T02:53:01+00:00

scsi_mid_low_api.rst refers to scsi_register() and scsi_unregister() but
these functions don't exist. They have been replaced by more meaningful
names.

Update one driver (megaraid_mbox.c) that uses "scsi_unregister" in a
warning message. Update scsi_mid_low_api.rst to eliminate references to
scsi_register() and scsi_unregister().

scsi: Rename .slave_alloc() and .slave_destroy()

2024-12-04T20:34:28+00:00

Rename .slave_alloc() into .sdev_init() and .slave_destroy() into
.sdev_destroy(). The new names make it clear that these are actions on
SCSI devices. Make this change in the SCSI core, SCSI drivers and also
in the ATA drivers. No functionality has been changed.

This patch has been created as follows:
* Change the text "slave_alloc" into "sdev_init" in all source files
  except those in drivers/net/ and Documentation/.
* Change the text "slave_destroy" into "sdev_destroy" in all source
  files except those in drivers/net/ and Documentation/.
* Rename lpfc_no_slave() into lpfc_no_sdev().
* Manually adjust whitespace where necessary to restore vertical
  alignment (dc395x driver and include/linux/libata.h).

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

	sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i
