The bin_attribute argument of bin_attribute::read() is now const.
This makes the _new() callbacks unnecessary. Switch all users back.

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.
Conversion was done with coccinelle plus manual fixups where necessary.

Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced
secs_to_jiffies(). As the value here is a multiple of 1000, use
secs_to_jiffies() instead of msecs_to_jiffies to avoid the multiplication.
This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with
the following Coccinelle rules:
@@ constant C; @@
- msecs_to_jiffies(C * 1000)
+ secs_to_jiffies(C)
@@ constant C; @@
- msecs_to_jiffies(C * MSEC_PER_SEC)

The only difference between the .sdev_configure() and .slave_configure()
methods is that the former accepts an additional 'limits' argument.
Convert all SCSI drivers that define a .slave_configure() method to
.sdev_configure(). This patch prepares for removing the
.slave_configure() method. No functionality has been changed.

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally reading across neighboring array fields.
pcmd->sense_buffer is 96 bytes, and was being manually zero-filled.
However, struct SENSE_DATA is 18 bytes, with ccb->arcmsr_cdb.SenseData only
being 15 bytes, resulting in a 3 byte over-read.
Copy only the contents of ccb->arcmsr_cdb.SenseData and zero fill the
remainder, avoiding potential over-reads.

Originally the SCSI subsystem has been using 'special' SCSI status codes,
which were the SAM-specified ones but shifted by 1. As most drivers have
now been modified to use the SAM-specified ones, having two nearly
identical sets of definitions only causes confusion.
The Linux-specifed SCSI status codes have been marked obsolete for several
years so drop them and use the SAM-specified status codes throughout.

Drivers should do only device-specific jobs. But in general, drivers using
legacy PCI PM framework for .suspend()/.resume() have to manage many PCI
PM-related tasks themselves which can be done by PCI Core itself. This
brings extra load on the driver and it directly calls PCI helper functions
to handle them.
Switch to the new generic framework by updating function signatures and
define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove
unnecessary calls to the PCI Helper functions along with the legacy
.suspend & .resume bindings.

The driver calls pci_enable_wake(...., false) in arcmsr_resume(), and there
is no corresponding pci_enable_wake(...., true) in arcmsr_suspend().
Either it should do enable-wake the device in .suspend() or should not
invoke pci_enable_wake() at all.
Concluding that this driver doesn't support enable-wake and PCI core calls
pci_enable_wake(pci_dev, PCI_D0, false) during resume, drop it from
arcmsr_resume().

Pull more SCSI updates from James Bottomley:
"The set of core changes here is Christoph's submission path cleanups.
These introduced a couple of regressions when first proposed so they
got held over from the initial merge window pull request to give more
testing time, which they've now had and Syzbot has confirmed the
regression it detected is fixed.
The other main changes are two driver updates (arcmsr, pm80xx) and
assorted minor clean ups"

Pull SCSI updates from James Bottomley:
"This series has a huge amount of churn because it pulls in Mauro's doc
update changing all our txt files to rst ones.
Excluding that, we have the usual driver updates (qla2xxx, ufs, lpfc,
zfcp, ibmvfc, pm80xx, aacraid), a treewide update for scnprintf and
some other minor updates.
The major core change is Hannes moving functions out of the aacraid
driver and into the core"

Call scsi_bios_ptable from scsi_partsize instead of requiring boilerplate
code in the callers. Also switch the calling convention to match that
of the ->bios_param instances calling this function, and use true/false
for the return value instead of the weird -1 convention.

This file had its own peculiar style, not following any other
files inside the Kernel (as far as I saw).
Had to do a number of changes here, starting by removing the two
leading asterisks from each line, adding table and literal
block markups and changing whitespace and blank lines.
The end result is that (IMHO), it is now a lot easier to read
it as a text file, while producing a good html output.
