powerpc/warp: Fix error handling in pika_dtm_thread
pika_dtm_thread() acquires client through of_find_i2c_device_by_node()
but fails to release it in error handling path. This could result in a
reference count leak, preventing proper cleanup and potentially
leading to resource exhaustion. Add put_device() to release the
reference in the error handling path.

powerpc: 82xx: fix uninitialized pointers with free attribute
Uninitialized pointers with `__free` attribute can cause undefined
behavior as the memory allocated to the pointer is freed automatically
when the pointer goes out of scope.
powerpc/km82xx doesn't have any bugs related to this as of now, but,
it is better to initialize and assign pointers with `__free` attribute
in one statement to ensure proper scope-based cleanup

powerpc/8xx: Fix interrupt mask in cpm1_gpiochip_add16()
Allthough fsl,cpm1-gpio-irq-mask always contains a 16 bits value,
it is a standard u32 OF property as documented in
Documentation/devicetree/bindings/soc/fsl/cpm_qe/gpio.txt
The driver erroneously uses of_property_read_u16() leading to a
mask which is always 0.
Fix it by using of_property_read_u32() instead.

pseries/papr-hvpipe: Fix the usage of copy_to_user()
copy_to_user() return bytes_not_copied to the user buffer. If there was
an error writing bytes into the user buffer, i.e. if copy_to_user
returns a non-zero value, then we should simply return -EFAULT from the
->read() call.
Otherwise, in the non-patched version, we may end up mixing
"bytes_not_copied + bytes_copied (HVPIPE_HDR_LEN)" as the return value
to the user in ->read() call
Also let's make sure we clear the hvpipe_status flag, if we have
consumed the hvpipe msg by making the rtas call. ret = -EFAULT means
copy_to_user has failed but that still means that the msg was read from
the hvpipe, hence for both cases, success & -EFAULT, we should clear the
HVPIPE_MSG_AVAILABLE flag in hvpipe_status.

pseries/papr-hvpipe: Fix & simplify error handling in papr_hvpipe_init()
Remove such 3 levels of nesting patterns to check success return values
from function calls.
ret = enable_hvpipe_IRQ()
if (!ret)
ret = set_hvpipe_sys_param(1)
if (!ret)
ret = misc_register()
Instead just bail out to "out*:" labels, in case of any error. This
simplifies the init flow.
While at it let's also fix the following error handling logic:
We have already enabled interrupt sources and enabled hvpipe to received
interrupts, if misc_register() fails, we will destroy the workqueue, but
the HMC might send us a msg via hvpipe which will call, queue work on
the workqueue which might be destroyed.
So instead, let's reverse the order of enabling set_hvpipe_sys_param(1)
and in case of an error let's remove the misc dev by calling
misc_deregister().

pseries/papr-hvpipe: Prevent kernel stack memory leak to userspace
The hdr variable is allocated on the stack and only hdr.version and
hdr.flags are initialized explicitly. Because the struct papr_hvpipe_hdr
contains reserved padding bytes (reserved[3] and reserved2[40]), these
could leak the uninitialized bytes to userspace after copy_to_user().
This patch fixes that by initializing the whole struct to 0.

powerpc/pseries/htmdump: Add memory configuration dump support to htmdump module
H_HTM (Hardware Trace Macro) hypervisor call has capability to capture SystemMemory Configuration. This information helps to understand the address mapping for the partitions in the system. Support dumping system memory configuration from Hardware Trace Macro (HTM) function via debugfs interface. Under debugfs folder "/sys/kernel/debug/powerpc/htmdump", add file "htmsystem_mem". The interface allows only read of this file which will present the content of HTM buffer from the hcall. The 16th offset of HTM buffer has value for the number of entries for array of processors.

powerpc/pseries/htmdump: Free the global buffers in htmdump module exit
htmdump modules uses global memory buffers to capture details like capabilities, status of specified HTM, read the trace buffer. These are initialized during module init and hence needs to be freed in module exit. Patch adds freeing of the memory in module exit. The change also includes minor clean up for the variable name. The read call back for the debugfs interface file saves filp->private_data to local variable name which is same as global variable name for the memory buffers. Rename these local variable names.

gpio updates for v7.1-rc1
GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software nodes
- allow matching GPIO controllers by secondary firmware node if matching
by primary does not succeed
- demote deferral warnings to debug level as they are quite normal when
using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig by
default
- rework several core functions in preparation for the upcoming Revocable
helper library for protecting resources against sudden removal, this
reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by using
FD_PREPARE()
- introduce a header defining symbols used by both GPIO consumers and
providers to avoid having to include provider-specific headers from
drivers which only consume GPIOs

New drivers:
- add the gpio-by-pinctrl generic driver using the ARM SCMI protocol to
control GPIOs (along with SCMI changes pulled from the pinctrl tree)

GPIO-signalled ACPI events (used on Intel Nova Lake and later platforms)
Driver changes:
- extend the gpio-kempld driver with support for more recent models,
interrupts and setting/getting multiple values at once
- improve interrupt handling in gpio-brcmstb
- add support for multi-SoC systems in gpio-tegra186
- make sure we return correct values from the .get() callbacks in several
GPIO drivers by normalizing any values other than 0, 1 or negative error
numbers
- use flexible arrays in several drivers to reduce the number of required
memory allocations
- simplify synchronous waiting for virtual drivers to probe and remove the
dedicated, a bit overengineered helper library dev-sync-probe
- remove unneeded Kconfig dependencies on OF_GPIO in several drivers and
subsystems
- convert the two remaining users of of_get_named_gpio() to using GPIO
descriptors and remove the (no longer used) function along with the
header that declares it

- allow to specify the active-low setting of simulated hogs over the
configfs interface (in addition to existing devicetree support) in
gpio-sim
Bug fixes:
- clear the OF_POPULATED flag on hog nodes in GPIO chip remove path on
OF systems
- fix resource leaks in error path in gpiochip_add_data_with_key()
- drop redundant device reference in gpio-mpsse
Tests:

DT bindings:
- add a DT binding document for SCMI based, gpio-over-pinctrl devices
- fix interrupt description in microchip,mpfs-gpio
- add new compatible for gpio-realtek-otto
- describe the resets of the mpfs-gpio controller

Misc:
- convert OMAP1 ams-delta board to using GPIO hogs described with software
nodes

Merge tag 'gpio-updates-for-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.
Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.
There's also a number of driver reworks and refactoring, documentation
updates, some bug-fixes and new tests.

- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet

powerpc: opal-core: pair alloc_pages_exact() with free_pages_exact()
opal-core allocates buffers with alloc_pages_exact(), but then marks them as reserved and frees using free_reserved_area(). This is completely unnecessary and the pages allocated with alloc_pages_exact() can be naturally freed with free_pages_exact(). Replace freeing of memory in opalcore_cleanup() with free_pages_exact() and simplify allocation code so that it won't mark allocated pages as reserved.

powerpc/44x/uic: Consolidate chained IRQ handler install/remove
The driver currently sets the handler data and the chained handler in two separate steps. This creates a theoretical race window where an interrupt could fire after the handler is set but before the data is assigned, leading to a NULL pointer dereference.

powerpc/pseries: Correct MSI allocation tracking
The per-device MSI allocation calculation in pseries_irq_domain_alloc()

Correct it.

powerpc: 83xx: km83xx: Fix keymile vendor prefix
When kmeter.c was refactored into km83xx.c in 2011, the "keymile" vendor
prefix was changed to upper-case "Keymile". The devicetree at
arch/powerpc/boot/dts/kmeter1.dts never underwent the same change,
suggesting that this was simply a mistake.

powerpc/e500: Always use 64 bits PTE
Today there are two PTE formats for e500: - The 64 bits format, used - On 64 bits kernel - On 32 bits kernel with 64 bits physical addresses - On 32 bits kernel with support of huge pages - The 32 bits format, used in other cases Maintaining two PTE formats means unnecessary maintenance burden because every change needs to be implemented and tested for both formats. Remove the 32 bits PTE format. The memory usage increase due to larger PTEs is minimal (approx. 0,1% of memory). This also means that from now on huge pages are supported also with 32 bits physical addresses.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument
This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org> |

Updates for the [PCI] MSI subsystem:
- Add interrupt redirection infrastructure
Some PCI controllers use a single demultiplexing interrupt for the MSI
interrupts of subordinate devices.
This prevents setting the interrupt affinity of device interrupts, which
causes device interrupts to be delivered to a single CPU. That obviously is
counterproductive for multi-queue devices and interrupt balancing.
To work around this limitation the new infrastructure installs a dummy
irq_set_affinity() callback which captures the affinity mask and picks a
redirection target CPU out of the mask.
When the PCI controller demultiplexes the interrupts it invokes a new
handling function in the core, which either runs the interrupt handler in
the context of the target CPU or delegates it to irq_work on the target CPU.
- Utilize the interrupt redirection mechanism in the PCI DWC host controller
driver.
This allows affinity control for the subordinate device MSI interrupts
instead of being randomly executed on the CPU which runs the demultiplex
handler.
- Replace the binary 64-bit MSI flag with a DMA mask
Some PCI devices have PCI_MSI_FLAGS_64BIT in the MSI capability, but
implement less than 64 address bits. This breaks on platforms where such a
device is assigned an MSI address higher than what's supported.
With the binary 64-bit flag there is no other choice than disabling 64-bit
MSI support which leaves the device disfunctional.
By using a DMA mask the address limit of a device can be described
correctly which provides support for the above scenario.
- Make use of the DMA mask based address limit in the hda/intel and radeon
drivers to enable them on affected platforms.
- The usual small cleanups and improvements
