The context bus is a "dummy" bus that contains struct devices that
correspond to IOMMU contexts assigned through Host1x to processes.
Even when host1x itself is built as a module, the bus is registered
in built-in code so that the built-in ARM SMMU driver is able to
reference it.

Guard ns_targets in struct bond_params by CONFIG_IPV6, which could save
256 bytes if IPv6 not configed. Also add this protection for function
bond_is_ip6_target_ok() and bond_get_targets_ip6().
Remove the IS_ENABLED() check for bond_opts[] as this will make
BOND_OPT_NS_TARGETS uninitialized if CONFIG_IPV6 not enabled. Add
a dummy bond_option_ns_ip6_targets_set() for this situation.

xen_remap() is used to establish mappings for frames not under direct
control of the kernel: for Xenstore and console ring pages, and for
grant pages of non-PV guests.
Today xen_remap() is defined to use ioremap() on x86 (doing uncached
mappings), and ioremap_cache() on Arm (doing cached mappings).
Uncached mappings for those use cases are bad for performance, so they
should be avoided if possible. As all use cases of xen_remap() don't
require uncached mappings (the mapped area is always physical RAM),
a mapping using the standard WB cache mode is fine.
As sparse is flagging some of the xen_remap() use cases to be not
appropriate for iomem(), as the result is not annotated with the
__iomem modifier, eliminate xen_remap() completely and replace all
use cases with memremap() specifying the MEMREMAP_WB caching mode.
xen_unmap() can be replaced with memunmap().

In qdisc_run_end(), the spin_unlock() only has store-release semantic,
which guarantees all earlier memory access are visible before it. But
the subsequent test_bit() has no barrier semantics so may be reordered
ahead of the spin_unlock(). The store-load reordering may cause a packet
stuck problem.
The concurrent operations can be described as below,
CPU 0 | CPU 1
qdisc_run_end() | qdisc_run_begin()
. | .
----> /* may be reorderd here */ | .
| . | .
| spin_unlock() | set_bit()
| . | smp_mb__after_atomic()
---- test_bit() | spin_trylock()
. | .
Consider the following sequence of events:
CPU 0 reorder test_bit() ahead and see MISSED = 0
CPU 1 calls set_bit()
CPU 1 calls spin_trylock() and return fail
CPU 0 executes spin_unlock()
At the end of the sequence, CPU 0 calls spin_unlock() and does nothing
because it see MISSED = 0. The skb on CPU 1 has beed enqueued but no one
take it, until the next cpu pushing to the qdisc (if ever ...) will
notice and dequeue it.
This patch fix this by adding one explicit barrier. As spin_unlock() and
test_bit() ordering is a store-load ordering, a full memory barrier
smp_mb() is needed here.

Pull f2fs updates from Jaegeuk Kim:
"In this round, we've refactored the existing atomic write support
implemented by in-memory operations to have storing data in disk
temporarily, which can give us a benefit to accept more atomic writes.
At the same time, we removed the existing volatile write support.
We've also revisited the file pinning and GC flows and found some
corner cases which contributeed abnormal system behaviours.
As usual, there're several minor code refactoring for readability,
sanity check, and clean ups.
Enhancements:
- allow compression for mmap files in compress_mode=user
- kill volatile write support
- change the current atomic write way
- give priority to select unpinned section for foreground GC
- introduce data read/write showing path info
- remove unnecessary f2fs_lock_op in f2fs_new_inode
Bug fixes:
- fix the file pinning flow during checkpoint=disable and GCs
- fix foreground and background GCs to select the right victims and
get free sections on time
- fix GC flags on defragmenting pages
- avoid an infinite loop to flush node pages
- fix fallocate to use file_modified to update permissions

This is a rework on the previous IRQ hardening that is done for
virtio-pci where several drawbacks were found and were reverted:
1) try to use IRQF_NO_AUTOEN which is not friendly to affinity managed IRQ
that is used by some device such as virtio-blk
2) done only for PCI transport
The vq->broken is re-used in this patch for implementing the IRQ
hardening. The vq->broken is set to true during both initialization
and reset. And the vq->broken is set to false in
virtio_device_ready(). Then vring_interrupt() can check and return
when vq->broken is true. And in this case, switch to return IRQ_NONE
to let the interrupt core aware of such invalid interrupt to prevent
IRQ storm.
The reason of using a per queue variable instead of a per device one
is that we may need it for per queue reset hardening in the future.
Note that the hardening is only done for vring interrupt since the
config interrupt hardening is already done in commit 22b7050a024d7
("virtio: defer config changed notifications"). But the method that is
used by config interrupt can't be reused by the vring interrupt
handler because it uses spinlock to do the synchronization which is
expensive.

This patches introduces the multiple address spaces support for vDPA
device. This idea is to identify a specific address space via an
dedicated identifier - ASID.
During vDPA device allocation, vDPA device driver needs to report the
number of address spaces supported by the device then the DMA mapping
ops of the vDPA device needs to be extended to support ASID.
This helps to isolate the environments for the virtqueue that will not
be assigned directly. E.g in the case of virtio-net, the control
virtqueue will not be assigned directly to guest.
As a start, simply claim 1 virtqueue groups and 1 address spaces for
all vDPA devices. And vhost-vDPA will simply reject the device with
more than 1 virtqueue groups or address spaces.

Allows to read vendor statistics of a vdpa device. The specific
statistics data are received from the upstream driver in the form of an
(attribute name, attribute value) pairs.
An example of statistics for mlx5_vdpa device are:
received_desc - number of descriptors received by the virtqueue
completed_desc - number of descriptors completed by the virtqueue
A descriptor using indirect buffers is still counted as 1. In addition,
N chained descriptors are counted correctly N times as one would expect.
A new callback was added to vdpa_config_ops which provides the means for
the vdpa driver to return statistics results.
The interface allows for reading all the supported virtqueues, including
the control virtqueue if it exists.
Below are some examples taken from mlx5_vdpa which are introduced in the
following patch:
1. Read statistics for the virtqueue at index 1
$ vdpa dev vstats show vdpa-a qidx 1
vdpa-a:
queue_type tx queue_index 1 received_desc 3844836 completed_desc 3844836
2. Read statistics for the virtqueue at index 32
$ vdpa dev vstats show vdpa-a qidx 32
vdpa-a:
queue_type control_vq queue_index 32 received_desc 62 completed_desc 62
3. Read statisitics for the virtqueue at index 0 with json output
$ vdpa -j dev vstats show vdpa-a qidx 0
{"vstats":{"vdpa-a":{
"queue_type":"rx","queue_index":0,"name":"received_desc","value":417776,\
"name":"completed_desc","value":417548}}}
4. Read statistics for the virtqueue at index 0 with preety json output
$ vdpa -jp dev vstats show vdpa-a qidx 0
{
"vstats": {
"vdpa-a": {
"queue_type": "rx",
"queue_index": 0,
"name": "received_desc",
"value": 417776,
"name": "completed_desc",
"value": 417548
}
}

RFC 9131 changes default behaviour of handling RX of NA messages when the
corresponding entry is absent in the neighbour cache. The current
implementation is limited to accept just unsolicited NAs. However, the
RFC is more generic where it also accepts solicited NAs. Both types
should result in adding a STALE entry for this case.
Expand accept_untracked_na behaviour to also accept solicited NAs to
be compliant with the RFC and rename the sysctl knob to
accept_untracked_na.

One big issue with the file registration feature is that it needs user
space apps to maintain free slot info about io_uring's fixed file table,
which really is a burden for development. io_uring now supports choosing
free file slot for user space apps by using IORING_FILE_INDEX_ALLOC flag
in accept, open, and socket operations, but they need the app to use
direct accept or direct open, which not all apps are prepared to use yet.
To support apps that still need real fds, make use of the registration
feature easier. Let IORING_OP_FILES_UPDATE support choosing fixed file
slots, which will store picked fixed files slots in fd array and let cqe
return the number of slots allocated.

When building the kernel for arm with the "-mabi=apcs-gnu" option, gcc
will force alignment of all structures and unions to a word boundary
(see also STRUCTURE_SIZE_BOUNDARY and the "-mstructure-size-boundary=XX"
option if you're a gcc person), even when the members of said structures
do not want or need said alignment.
This completely messes up the structure alignment of 'struct edid' on
those targets, because even though all the embedded structures are
marked with "__attribute__((packed))", the unions that contain them are
not.
This was exposed by commit f1e4c916f97f ("drm/edid: add EDID block count
and size helpers"), but the bug is pre-existing. That commit just made
the structure layout problem cause a build failure due to the addition
of the
BUILD_BUG_ON(sizeof(*edid) != EDID_LENGTH);
sanity check in drivers/gpu/drm/drm_edid.c:edid_block_data().
This legacy union alignment should probably not be used in the first
place, but we can fix the layout by adding the packed attribute to the
union entries even when each member is already packed and it shouldn't
matter in a sane build environment.
You can see this issue with a trivial test program:
union {
struct {
char c[5];
};
struct {
char d;
unsigned e;
} __attribute__((packed));
} a = { "1234" };
where building this with a normal "gcc -S" will result in the expected
5-byte size of said union:
.type a, @object
.size a, 5
but with an ARM compiler and the old ABI:
arm-linux-gnu-gcc -mabi=apcs-gnu -mfloat-abi=soft -S t.c
you get
.type a, %object
.size a, 8
instead, because even though each member of the union is packed, the
union itself still gets aligned.
This was reported by Sudip for the spear3xx_defconfig target.

Let the caller set it together with the end_io_data instead of passing
a pointless argument. Note the the target code did in fact already
set it and then just overrode it again by calling blk_execute_rq_nowait.

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for this cycle.
The highlight is new driver-core infrastructure and CXL subsystem
changes for allowing lockdep to validate device_lock() usage. Thanks
to PeterZ for setting me straight on the current capabilities of the
lockdep API, and Greg acked it as well.
On the CXL ACPI side this update adds support for CXL _OSC so that
platform firmware knows that it is safe to still grant Linux native
control of PCIe hotplug and error handling in the presence of CXL
devices. A circular dependency problem was discovered between suspend
and CXL memory for cases where the suspend image might be stored in
CXL memory where that image also contains the PCI register state to
restore to re-enable the device. Disable suspend for now until an
architecture is defined to clarify that conflict.
Lastly a collection of reworks, fixes, and cleanups to the CXL
subsystem where support for snooping mailbox commands and properly
handling the "mem_enable" flow are the highlights.
Summary:
- Add driver-core infrastructure for lockdep validation of
device_lock(), and fixup a deadlock report that was previously
hidden behind the 'lockdep no validate' policy.
- Add CXL _OSC support for claiming native control of CXL hotplug and
error handling.
- Disable suspend in the presence of CXL memory unless and until a
protocol is identified for restoring PCI device context from memory
hosted on CXL PCI devices.
- Add support for snooping CXL mailbox commands to protect against
inopportune changes, like set-partition with the 'immediate' flag
set.
- Rework how the driver detects legacy CXL 1.1 configurations (CXL
DVSEC / 'mem_enable') before enabling new CXL 2.0 decode
configurations (CXL HDM Capability).
- Miscellaneous cleanups and fixes from -next exposure"

BLK_STS_AGAIN should only be used if RQF_NOWAIT is set and the bio
would block. So we'd better document that to avoid accidental misuse.

Pull libnvdimm and DAX updates from Dan Williams:
"New support for clearing memory errors when a file is in DAX mode,
alongside with some other fixes and cleanups.
Previously it was only possible to clear these errors using a truncate
or hole-punch operation to trigger the filesystem to reallocate the

as well.
This change spans x86/mm, nvdimm, and fs/dax, and has received the
appropriate sign-offs. Thanks to Jane for her work on this.

Pull clk updates from Stephen Boyd:
"Mainly driver updates this time around.
There's a single patch to the core clk framework that simplifies a
runtime PM call. Otherwise the majority of the diff falls to a few SoC
drivers: Qualcomm, STM32 and MediaTek. Those SoCs gain some new
hardware support and what comes along with that is quite a few lines
of data and some clk_ops code.
Beyond the new hardware support we have the usual pile of driver
updates that add missing clks on already supported SoCs or fix up
problems like bad clk tree descriptions. It's nice to see that more
drivers are moving to clk_hw based APIs too.
New Drivers:
- Add STM32MP13 RCC driver (Reset Clock Controller)
- MediaTek MT8186 SoC clk support
- Airoha EN7523 SoC system clocks
- Clock driver for exynosautov9 SoC
- Renesas R-Car V4H and RZ/V2M SoCs
- Renesas RZ/G2UL SoC
- LPASS clk driver for Qualcomm sc7280 SoC
- GCC clk driver for Qualcomm SC8280XP SoC
Updates:
- SDCC uses floor clk ops on Qualcomm MSM8976
- Add modem reset and fix RPM clks on Qualcomm MSM8976
- Add the two missing CLKOUT clocks for U8500/DB8500 SoC
- Mark some clks critical on Ingenic X1000
- Convert ux500 to clk_hw
- Move MediaTek driver to clk_hw provider APIs
- Use i2c driver probe_new to avoid id scans
- Convert a number of Rockchip dt bindings to YAML
- Mark hclk_vo critical on Rockchip rk3568
- Use pm_runtime_resume_and_get to fix pm_runtime_get_sync() usage
- Various cleanups like memory allocation error checks and plugged
leaks
- Allwinner H6 RTC clock support
- Allwinner H616 32 kHz clock support
- Add the Universal Flash Storage clock on Renesas R-Car S4-8
- Add I2C, SSIF-2 (sound), USB, CANFD, OSTM (timer), WDT, SPI Multi
I/O Bus, RSPI, TSU (thermal), and ADC clocks and resets on Renesas
RZ/G2UL
- Add display clock support on Renesas RZ/G2L
- Add RPC (QSPI/HyperFlash) clocks on Renesas R-Car E3 and D3
- Add 27 MHz phy PLL ref clock on i.MX
- Add mcore_booted module parameter to tell kernel M core has already
booted for i.MX
- Remove snvs clock on i.MX because it was for secure world only
- Add dt bindings for i.MX8MN GPT
- Add DISP2 pixel clock for i.MX8MP
- Add clkout1/2 for i.MX8MP
- Fix parent clock of ubs_root_clk for i.MX8MP
