In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for
those drivers requiring them. For the DEFXX driver the use of I/O
ports is optional and we only need to fence specific code paths. It also
turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need
the !S390 dependency and successfully builds the bpqether driver.

through ifr_data, but the use of a pointer in s_skfp_ioctl is

Replace repeated "defxx" strings with a reference to the DRV_NAME macro
and then use the driver's name rather that the bus address with resource
requests so as to have contents of /proc/iomem and /proc/ioports more
meaningful to the user, in line with what drivers usually do.
So rather than say:

Recent versions of the PCI Express specification have deprecated support
for I/O transactions and actually some PCIe host bridges, such as Power
Systems Host Bridge 4 (PHB4), do not implement them. Conversely a DEFEA
adapter can have its MMIO decoding disabled with ECU (EISA Configuration
Utility) and therefore not available for us with the resource allocation
infrastructure we implement.
However either I/O address space will always be available for use with
the DEFEA (EISA) and DEFPA (PCI) adapters and both have double address
decoding implemented in hardware for Control and Status Register access.
The two kinds of adapters can be present both at once in a single mixed
PCI/EISA system. For the DEFTA (TURBOchannel) variant there is no issue
as there has been no port I/O address space defined for that bus.
To make people's life easier and the driver more robust remove the
DEFXX_MMIO configuration option so as to rather than making the choice
for the I/O address space to use at build time for all the adapters
installed in the system let the driver choose the most suitable address
space dynamically on a case-by-case basis at run time. Make MMIO the
default and resort to port I/O should the default fail for some reason.
This way multiple adapters installed in one system can use different I/O
address spaces each, in particular in the presence of DEFEA adapters in
a pure-EISA or a mixed EISA/PCI system (it is expected that DEFPA boards
will use MMIO in normal circumstances).
The choice of the I/O address space to use continues being reported by
the driver on startup, e.g.:
eisa 00:05: EISA: slot 5: DEC3002 detected
defxx: v1.12 2021/03/10 Lawrence V. Stefani and others
00:05: DEFEA at I/O addr = 0x5000, IRQ = 10, Hardware addr = 00-00-f8-c8-b3-b6
00:05: registered as fddi0
and:
defxx: v1.12 2021/03/10 Lawrence V. Stefani and others
0031:02:04.0: DEFPA at MMIO addr = 0x620c080020000, IRQ = 57, Hardware addr = 00-60-6d-93-91-98
0031:02:04.0: registered as fddi0
and:
defxx: v1.12 2021/03/10 Lawrence V. Stefani and others
tc2: DEFTA at MMIO addr = 0x1f100000, IRQ = 21, Hardware addr = 08-00-2b-b0-8b-1e
tc2: registered as fddi0
so there is no need to add further information.
The change is supposed to cause a negligible performance hit as I/O
accessors will now have code executed conditionally at run time.

Recent versions of the PCI Express specification have deprecated support
for I/O transactions and actually some PCIe host bridges, such as Power
Systems Host Bridge 4 (PHB4), do not implement them.
The default kernel configuration choice for the defxx driver is the use
of I/O ports rather than MMIO for PCI and EISA systems. It may have
made sense as a conservative backwards compatible choice back when MMIO
operation support was added to the driver as a part of TURBOchannel bus
support. However nowadays this configuration choice makes the driver
unusable with systems that do not implement I/O transactions for PCIe.
Make DEFXX_MMIO the configuration default then, except where configured
for EISA. This exception is because an EISA adapter can have its MMIO
decoding disabled with ECU (EISA Configuration Utility) and therefore
not available with the resource allocation infrastructure we implement,
while port I/O is always readily available as it uses slot-specific
addressing, directly mapped to the slot an option card has been placed
in and handled with our EISA bus support core. Conversely a kernel that
supports modern systems which may not have I/O transactions implemented
for PCIe will usually not be expected to handle legacy EISA systems.
The change of the default will make it easier for people, including but
not limited to distribution packagers, to make a working choice for the
driver.
Update the option description accordingly and while at it replace the
potentially ambiguous PIO acronym with IOP for "port I/O" vs "I/O ports"
according to our nomenclature used elsewhere.

Recent versions of the PCI Express specification have deprecated support
for I/O transactions and actually some PCIe host bridges, such as Power
Systems Host Bridge 4 (PHB4), do not implement them.
For those systems the PCI BARs that request a mapping in the I/O space
have the length recorded in the corresponding PCI resource set to zero,
which makes it unassigned:
# lspci -s 0031:02:04.0 -v
0031:02:04.0 FDDI network controller: Digital Equipment Corporation PCI-to-PDQ Interface Chip [PFI] FDDI (DEFPA) (rev 02)

Flags: bus master, medium devsel, latency 136, IRQ 57, NUMA node 8

I/O ports at <unassigned> [disabled]

Capabilities: [50] Power Management version 2
Kernel driver in use: defxx
Kernel modules: defxx
#
Regardless the driver goes ahead and requests it (here observed with a
Raptor Talos II POWER9 system), resulting in an odd /proc/ioport entry:
# cat /proc/ioports
00000000-ffffffffffffffff : 0031:02:04.0
#
Furthermore, the system gets confused as the driver actually continues
and pokes at those locations, causing a flood of messages being output
to the system console by the underlying system firmware, like:
defxx: v1.11 2014/07/01 Lawrence V. Stefani and others
defxx 0031:02:04.0: enabling device (0140 -> 0142)
LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010000
IPMI: dropping non severe PEL event
LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010014
IPMI: dropping non severe PEL event
LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010014
IPMI: dropping non severe PEL event
and so on and so on (possibly intermixed actually, as there's no locking
between the kernel and the firmware in console port access with this
particular system, but cleaned up above for clarity), and once some 10k
of such pairs of the latter two messages have been produced an interace
eventually shows up in a useless state:
0031:02:04.0: DEFPA at I/O addr = 0x0, IRQ = 57, Hardware addr = 00-00-00-00-00-00
This was not expected to happen as resource handling was added to the
driver a while ago, because it was not known at that time that a PCI
system would be possible that cannot assign port I/O resources, and
oddly enough `request_region' does not fail, which would have caught it.
Correct the problem then by checking for the length of zero for the CSR
resource and bail out gracefully refusing to register an interface if
that turns out to be the case, producing messages like:
defxx: v1.11 2014/07/01 Lawrence V. Stefani and others
0031:02:04.0: Cannot use I/O, no address set, aborting
0031:02:04.0: Recompile driver with "CONFIG_DEFXX_MMIO=y"
Keep the original check for the EISA MMIO resource as implemented,
because in that case the length is hardwired to 0x400 as a consequence
of how the compare/mask address decoding works in the ESIC chip and it
is only the base address that is set to zero if MMIO has been disabled
for the adapter in EISA configuration, which in turn could be a valid
bus address in a legacy-free system implementing PCI, especially for
port I/O.
Where the EISA MMIO resource has been disabled for the adapter in EISA
configuration this arrangement keeps producing messages like:
eisa 00:05: EISA: slot 5: DEC3002 detected
defxx: v1.11 2014/07/01 Lawrence V. Stefani and others
00:05: Cannot use MMIO, no address set, aborting
00:05: Recompile driver with "CONFIG_DEFXX_MMIO=n"
00:05: Or run ECU and set adapter's MMIO location
with the last two lines now swapped for easier handling in the driver.
There is no need to check for and catch the case of a port I/O resource
not having been assigned for EISA as the adapter uses the slot-specific
I/O space, which gets assigned by how EISA has been specified and maps
directly to the particular slot an option card has been placed in. And
the EISA variant of the adapter has additional registers that are only
accessible via the port I/O space anyway.
While at it factor out the error message calls into helpers and fix an
argument order bug with the `pr_err' call now in `dfx_register_res_err'.

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Refactor the code according to the use of flexible-array members in
smt_sif_operation structure, instead of one-element arrays. Also, make
use of the struct_size() helper instead of the open-coded version
to calculate the size of the struct-with-flex-array. Additionally, make
use of the typeof operator to properly determine the object type to be
passed to macro smtod().
Also, this helps the ongoing efforts to enable -Warray-bounds by fixing
the following warnings:

it.

One-element arrays are being deprecated[1]. Replace the one-element array
with a simple object of type u_char: 'u_char rm_pad1'[2], once it seems
this is just a placeholder for padding.

While we're at it, remove some code which has never been invoked.
Keep the comment though, as it seems potentially half useful.

kbuild test robot found that addr_to_string() is available only when
DEBUG is defined. And I found that what that function is doing is
what %pM will do. Thus, replace %s with %pM and remove thread-unsafe
addr_to_string() function.
