The IXP4XX_EXP_T1_MASK was shifted one bit to the right, overlapping
IXP4XX_EXP_T2_MASK and leaving bit 29 unused. The offset being wrong is
also confirmed at least by the datasheet of IXP45X/46X [1].
Fix this by aligning it to IXP4XX_EXP_T1_SHIFT.

Changes in VFIO caused a pseudo-device to be created as child of
fsl-mc devices causing a crash [1] when trying to bind a fsl-mc
device to VFIO. Fix this by checking the device type when enumerating
fsl-mc child devices.

The value returned by an fsl-mc driver's remove function is mostly
ignored. (Only an error message is printed if the value is non-zero
and then device removal continues unconditionally.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Instead of silently returning an error in the remove callback (which yields
a generic and little informing error message), annotate each error path of
fsl_mc_resource_pool_remove_device() with an error message and return zero
in the remove callback to suppress the error message.
Note that changing the return value has no other effect than suppressing
the error message by the fsl_mc bus driver.

If fsl_mc_is_allocatable(mc_dev) evaluates to false, the driver won't
have bound to that device and then fsl_mc_allocator_remove() is never
called for that device. fsl_mc_allocator_remove() is the only caller of
fsl_mc_resource_pool_remove_device(), so the same check can be removed
from there.

The error message emitted in fsl_mc_driver_remove() is very generic.
Replace it by a message that mentions the reason for the failure.
Returning zero instead of a negative value has no side effect apart from
suppressing the generic error message.
The first if condition in dprc_remove() can never be true, as this would
prevent successful probing of the device and then .remove wasn't called.
So this can just be dropped.

If a platform driver's remove function returns an error code, this
results in a (generic and little helpful) error message. Otherwise the
value is ignored.
As fsl_mc_driver_remove() already emit an error message, return 0 also
in the error case. The only effect is to suppress the device core's
error message.

git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux
Pull module updates from Luis Chamberlain:
"The summary of the changes for this pull requests is:
- Song Liu's new struct module_memory replacement
- Nick Alcock's MODULE_LICENSE() removal for non-modules
- My cleanups and enhancements to reduce the areas where we vmalloc
module memory for duplicates, and the respective debug code which
proves the remaining vmalloc pressure comes from userspace.
Most of the changes have been in linux-next for quite some time except
the minor fixes I made to check if a module was already loaded prior
to allocating the final module memory with vmalloc and the respective
debug code it introduces to help clarify the issue. Although the
functional change is small it is rather safe as it can only *help*
reduce vmalloc space for duplicates and is confirmed to fix a bootup
issue with over 400 CPUs with KASAN enabled. I don't expect stable
kernels to pick up that fix as the cleanups would have also had to
have been picked up. Folks on larger CPU systems with modules will
want to just upgrade if vmalloc space has been an issue on bootup.
Given the size of this request, here's some more elaborate details:
The functional change change in this pull request is the very first
patch from Song Liu which replaces the 'struct module_layout' with a
new 'struct module_memory'. The old data structure tried to put
together all types of supported module memory types in one data
structure, the new one abstracts the differences in memory types in a
module to allow each one to provide their own set of details. This
paves the way in the future so we can deal with them in a cleaner way.
If you look at changes they also provide a nice cleanup of how we
handle these different memory areas in a module. This change has been
in linux-next since before the merge window opened for v6.3 so to
provide more than a full kernel cycle of testing. It's a good thing as
quite a bit of fixes have been found for it.
Jason Baron then made dynamic debug a first class citizen module user
by using module notifier callbacks to allocate / remove module
specific dynamic debug information.
Nick Alcock has done quite a bit of work cross-tree to remove module
license tags from things which cannot possibly be module at my request
so to:
a) help him with his longer term tooling goals which require a
deterministic evaluation if a piece a symbol code could ever be
part of a module or not. But quite recently it is has been made
clear that tooling is not the only one that would benefit.
Disambiguating symbols also helps efforts such as live patching,
kprobes and BPF, but for other reasons and R&D on this area is
active with no clear solution in sight.
b) help us inch closer to the now generally accepted long term goal
of automating all the MODULE_LICENSE() tags from SPDX license tags
In so far as a) is concerned, although module license tags are a no-op
for non-modules, tools which would want create a mapping of possible
modules can only rely on the module license tag after the commit
8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf").
Nick has been working on this *for years* and AFAICT I was the only
one to suggest two alternatives to this approach for tooling. The
complexity in one of my suggested approaches lies in that we'd need a
possible-obj-m and a could-be-module which would check if the object
being built is part of any kconfig build which could ever lead to it
being part of a module, and if so define a new define
-DPOSSIBLE_MODULE [0].
A more obvious yet theoretical approach I've suggested would be to
have a tristate in kconfig imply the same new -DPOSSIBLE_MODULE as
well but that means getting kconfig symbol names mapping to modules
always, and I don't think that's the case today. I am not aware of
Nick or anyone exploring either of these options. Quite recently Josh
Poimboeuf has pointed out that live patching, kprobes and BPF would
benefit from resolving some part of the disambiguation as well but for
other reasons. The function granularity KASLR (fgkaslr) patches were
mentioned but Joe Lawrence has clarified this effort has been dropped
with no clear solution in sight [1].
In the meantime removing module license tags from code which could
never be modules is welcomed for both objectives mentioned above. Some
developers have also welcomed these changes as it has helped clarify
when a module was never possible and they forgot to clean this up, and
so you'll see quite a bit of Nick's patches in other pull requests for
this merge window. I just picked up the stragglers after rc3. LWN has
good coverage on the motivation behind this work [2] and the typical
cross-tree issues he ran into along the way. The only concrete blocker
issue he ran into was that we should not remove the MODULE_LICENSE()
tags from files which have no SPDX tags yet, even if they can never be
modules. Nick ended up giving up on his efforts due to having to do
this vetting and backlash he ran into from folks who really did *not
understand* the core of the issue nor were providing any alternative /
guidance. I've gone through his changes and dropped the patches which
dropped the module license tags where an SPDX license tag was missing,
it only consisted of 11 drivers. To see if a pull request deals with a
file which lacks SPDX tags you can just use:
./scripts/spdxcheck.py -f \
$(git diff --name-only commid-id | xargs echo)
You'll see a core module file in this pull request for the above, but
that's not related to his changes. WE just need to add the SPDX
license tag for the kernel/module/kmod.c file in the future but it
demonstrates the effectiveness of the script.
Most of Nick's changes were spread out through different trees, and I
just picked up the slack after rc3 for the last kernel was out. Those
changes have been in linux-next for over two weeks.
The cleanups, debug code I added and final fix I added for modules
were motivated by David Hildenbrand's report of boot failing on a
systems with over 400 CPUs when KASAN was enabled due to running out
of virtual memory space. Although the functional change only consists
of 3 lines in the patch "module: avoid allocation if module is already
present and ready", proving that this was the best we can do on the
modules side took quite a bit of effort and new debug code.
The initial cleanups I did on the modules side of things has been in
linux-next since around rc3 of the last kernel, the actual final fix
for and debug code however have only been in linux-next for about a
week or so but I think it is worth getting that code in for this merge
window as it does help fix / prove / evaluate the issues reported with
larger number of CPUs. Userspace is not yet fixed as it is taking a
bit of time for folks to understand the crux of the issue and find a
proper resolution. Worst come to worst, I have a kludge-of-concept [3]
of how to make kernel_read*() calls for modules unique / converge
them, but I'm currently inclined to just see if userspace can fix this
instead"

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing

So remove it in the files in this commit, none of which can be built as

Pull char/misc drivers updates from Greg KH:
"Here is the "big" set of char/misc and other driver subsystems for
6.4-rc1.
It's pretty big, but due to the removal of pcmcia drivers, almost
breaks even for number of lines added vs. removed, a nice change.
Included in here are:
- removal of unused PCMCIA drivers (finally!)
- Interconnect driver updates and additions
- Lots of IIO driver updates and additions
- MHI driver updates
- Coresight driver updates
- NVMEM driver updates, which required some OF updates
- W1 driver updates and a new maintainer to manage the subsystem
- FPGA driver updates
- New driver subsystem, CDX, for AMD systems
- lots of other small driver updates and additions
All of these have been in linux-next for a while with no reported
issues"

Manivannan writes:
MHI Host
========
Core
----
- Removed the "mhi_poll()" API as there are no in-kernel users available at the
moment.
- Added range check for the CHDBOFF and ERDBOFF registers in case the device
reports bad values.
- Fixed the errno for the rest of the range checks to use -ERANGE.
- Modified the event ring handlers to ring the doorbell only if there are
any pending elements in the ring to process for the device.
- Removed the check for EE (Execution Environment) while processing the SYS_ERR
transition as it creates device recovery issues when SBL (Secondary
Bootloader) crashes early.
- Used mhi_tryset_pm_state() API to set the error state instead of open coding
if the firmware loading fails. This avoids the race with other pm_state
updates.
pci_generic
-----------
- Dropped the dedundant pci_{enable/disable}_pcie_error_reporting() calls from
driver probe's error path as the PCI core itself takes care of that now.
- Revered the commit 2d5253a096c6 ("bus: mhi: host: pci_generic: Add a secondary
AT port to Telit FN990") as it turned out to be erroneous. This happened due
to the patch adding secondary AT port for FN990 getting applied through NET
and MHI trees and this caused two commits for the same functionality but one
of them ended up wrong.
- Added support for Foxconn T99W510 modem based on SDX24 chipset from Qualcomm.
MHI Endpoint
============
- Demoted the channel not supported error log to debug as not all devices will
support all channels defined in MHI spec and this may spam users.

If firmware loading fails, the controller's pm_state is updated to
MHI_PM_FW_DL_ERR unconditionally. This can corrupt the pm_state as the
update is not done under the proper lock, and also does not validate
the state transition. The firmware loading can fail due to a detected
syserr, but if MHI_PM_FW_DL_ERR is unconditionally set as the pm_state,
the handling of the syserr can break when it attempts to transition from
syserr detect, to syserr process.
By grabbing the lock, we ensure we don't race with some other pm_state
update. By using mhi_try_set_pm_state(), we check that the transition
to MHI_PM_FW_DL_ERR is valid via the state machine logic. If it is not
valid, then some other transition is occurring like syserr processing, and
we assume that will resolve the firmware loading error.

If we detect a system error via intvec, we only process the syserr if the
current ee is different than the last observed ee. The reason for this
check is to prevent bhie from running multiple times, but with the single
queue handling syserr, that is not possible.
The check can cause an issue with device recovery. If PBL loads a bad SBL
via BHI, but that SBL hangs before notifying the host of an ee change,
then issuing soc_reset to crash the device and retry (after supplying a
fixed SBL) will not recover the device as the host will observe a PBL->PBL
transition and not process the syserr. The device will be stuck until
either the driver is reloaded, or the host is rebooted. Instead, remove
the check so that we can attempt to recover the device.

Currently, mhi_process_data_event_ring()/mhi_process_ctrl_ev_ring() APIs
are ringing DB even if there are no ring elements to process. This could
cause the device to process the DB event in the absence of ring elements.
So to avoid this unnecessary device processing, let's ring event DB only
if there are any ring elements to process.

If the value read from the CHDBOFF and ERDBOFF registers is outside the
range of the MHI register space then an invalid address might be computed
which later causes a kernel panic. Range check the read value to prevent
a crash due to bad data from the device.

This reverts commit 2d5253a096c6057bbf7caa5520856dcdf7eca8bb.
There are 2 commits with commit message "Add a secondary AT port to Telit
FN990":
commit 2d5253a096c6 ("bus: mhi: host: pci_generic: Add a secondary AT port
to Telit FN990")
commit 479aa3b0ec2e ("bus: mhi: host: pci_generic: Add a secondary AT port
to Telit FN990")
This turned out to be due to the patch getting applied through different
trees and git settled on a resolution while applying it second time. But
the second AT port of Foxconn devices don't work in PCIe mode. So the
second commit needs to be reverted.

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since commit <f26e58bf6f54> ("PCI/AER: Enable error reporting
when AER is native"), the PCI core does this for all devices during
enumeration, so the driver doesn't need to do it itself.
Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
Note that this only controls ERR_* Messages from the device. An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

Not all MHI endpoints will support all available channels. Most of them
support only a selected number of channels based on the implementations.
In those cases, it is not needed to print error messages in the endpoint.
So let's demote the error log to debug.

mhi_poll() API is not used within the MHI stack and also not by any client
drivers in mainline. So let's remove it until any consumer is available.

Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening
in the driver core in the quest to be able to move "struct bus" and
"struct class" into read-only memory, a task now complete with these
changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules
for all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most
of them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
All of these have been in linux-next for a while with no reported
problems"

zram: fix up permission for the hot_add sysfs file
cacheinfo: Add use_arch[|_cache]_info field/function

struct bus_type should never be modified in a sysfs callback as there is
nothing in the structure to modify, and frankly, the structure is almost
never used in a sysfs callback, so mark it as constant to allow struct
bus_type to be moved to read-only memory.

git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull more devicetree updates from Rob Herring:
- First part of DT header detangling dropping cpu.h from of_device.h
and replacing some includes with forward declarations. A handful of
drivers needed some adjustment to their includes as a result.
- Refactor of_device.h to be used by bus drivers rather than various
device drivers. This moves non-bus related functions out of
of_device.h. The end goal is for of_platform.h and of_device.h to
stop including each other.
- Refactor open coded parsing of "ranges" in some bus drivers to use DT
address parsing functions
- Add some new address parsing functions of_property_read_reg(),
of_range_count(), and of_range_to_resource() in preparation to
convert more open coded parsing of DT addresses to use them.
- Treewide clean-ups to use of_property_read_bool() and
of_property_present() as appropriate. The ones here are the ones that
didn't get picked up elsewhere.

We introduce a new HAS_IOPORT Kconfig option to indicate support for I/O
Port access. In a future patch HAS_IOPORT=n will disable compilation of
the I/O accessor functions inb()/outb() and friends on architectures
which can not meaningfully support legacy I/O spaces such as s390.
The following architectures do not select HAS_IOPORT:
* ARC
* C-SKY
* Hexagon
* Nios II
* OpenRISC
* s390
* User-Mode Linux
* Xtensa
All other architectures select HAS_IOPORT at least conditionally.
The "depends on" relations on HAS_IOPORT in drivers as well as ifdefs
for HAS_IOPORT specific sections will be added in subsequent patches on
a per subsystem basis.
