If we loop for multishot receive on the initial attempt, and then abort
later on to wait for more, we miss a case where we should be copying the
io_async_msghdr from the stack to stable storage. This leads to the next
retry potentially failing, if the application had the msghdr on the
stack.

PM runtime can be done simultaneously with AER error handling. Avoid that
by using pm_runtime_get_sync() before and pm_runtime_put() after reset in
pcie_do_recovery() for all recovering devices.
pm_runtime_get_sync() will increase dev->power.usage_count counter to
prevent any possible future request to runtime suspend a device. It will
also resume a device, if it was previously in D3hot state.
I tested with igc device by doing simultaneous aer_inject and rpm
suspend/resume via /sys/bus/pci/devices/PCI_ID/power/control and can
reproduce:
igc 0000:02:00.0: not ready 65535ms after bus reset; giving up
pcieport 0000:00:1c.2: AER: Root Port link has been reset (-25)
pcieport 0000:00:1c.2: AER: subordinate device reset failed
pcieport 0000:00:1c.2: AER: device recovery failed
igc 0000:02:00.0: Unable to change power state from D3hot to D0, device inaccessible
The problem disappears when this patch is applied.

Calling irq_domain_remove() will lead to freeing the IRQ domain
prematurely. The domain is still referenced and will be attempted to get
used via rmi_free_function_list() -> rmi_unregister_function() ->
irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer.
With PaX's MEMORY_SANITIZE this will lead to an access fault when
attempting to dereference embedded pointers, as in Torsten's report that
was faulting on the 'domain->ops->unmap' test.
Fix this by releasing the IRQ domain only after all related IRQs have
been deactivated.

__uint() macro that is used to specify map attributes like:
__uint(type, BPF_MAP_TYPE_ARRAY);
__uint(map_flags, BPF_F_MMAPABLE);
It is limited to 32-bit, since BTF_KIND_ARRAY has u32 "number of elements"
field in "struct btf_array".
Introduce __ulong() macro that allows specifying values bigger than 32-bit.
In map definition "map_extra" is the only u64 field, so far.

Recognize 'void *p__map' kfunc argument as 'struct bpf_map *p__map'.
It allows kfunc to have 'void *' argument for maps, since bpf progs
will call them as:
struct {
__uint(type, BPF_MAP_TYPE_ARENA);
...
} arena SEC(".maps");
bpf_kfunc_with_map(... &arena ...);
Underneath libbpf will load CONST_PTR_TO_MAP into the register via ld_imm64
insn. If kfunc was defined with 'struct bpf_map *' it would pass the
verifier as well, but bpf prog would need to type cast the argument
(void *)&arena, which is not clean.

Drivers can return -ENODEV or -ENXIO from their probe to reject a device
match, and return -EPROBE_DEFER if probe should be retried. Any other
error code is not expected during normal behavior and indicates an
issue occurred, so it should be logged at the error level.
Also make use of the device variant, dev_err(), so that the device
metadata is attached to the log message.

A fwnode link between specific supplier-consumer fwnodes can be added
multiple times for multiple reasons. If that dependency doesn't exist,
deleting the fwnode link once doesn't guarantee that it won't get created
again.
So, add FWLINK_FLAG_IGNORE flag to mark a fwnode link as one that needs to
be completely ignored. Since a fwnode link's flags is an OR of all the
flags passed to all the fwnode_link_add() calls to create that specific
fwnode link, the FWLINK_FLAG_IGNORE flag is preserved and can be used to
mark a fwnode link as on that need to be completely ignored until it is
deleted.

Ben Greear further reports deadlocks during concurrent debugfs
remove while files are being accessed, even though the code in
question now uses debugfs cancellations. Turns out that despite
all the review on the locking, we missed completely that the
logic is wrong: if the refcount hits zero we can finish (and
need not wait for the completion), but if it doesn't we have
to trigger all the cancellations. As written, we can _never_
get into the loop triggering the cancellations. Fix this, and
explain it better while at it.

Use the UIO_MEM_DMA_COHERENT type to properly handle mmap for
dma_alloc_coherent buffers.
The cnic l2_ring and l2_buf mmaps have caused page refcount issues as
the dma_alloc_coherent no longer provide __GFP_COMP allocation as per
commit "dma-mapping: reject __GFP_COMP in dma_alloc_attrs".
Fix this by having the uio device use dma_mmap_coherent.
The bnx2 and bnx2x status block allocations are also dma_alloc_coherent,
and should use dma_mmap_coherent. They don't allocate multiple pages,
but this interface does not work correctly with an iommu enabled unless
dma_mmap_coherent is used.

Add CDX-MSI domain per CDX controller with gic-its domain as
a parent, to support MSI for CDX devices. CDX devices allocate
MSIs from the CDX domain. Also, introduce APIs to alloc and free
IRQs for CDX domain.
In CDX subsystem firmware is a controller for all devices and
their configuration. CDX bus controller sends all the write_msi_msg
commands to firmware running on RPU and the firmware interfaces with
actual devices to pass this information to devices
Since, CDX controller is the only way to communicate with the Firmware
for MSI write info, CDX domain per controller required in contrast to
having a CDX domain per device.

Commit f77bf01425b1 ("kbuild: introduce ccflags-y, asflags-y and
ldflags-y") deprecates use of EXTRA_CFLAGS in the kernel build.
This has been cleaned up in the whole kernel tree long ago, but this one
single place must have been missed.
Replace the EXTRA_CFLAGS use by the common pattern for such debug flags.
No functional change.

/dev/synth has always been 8bit, but applications nowadays mostly
expect to be using utf-8 encoding. This adds /dev/synthu to be able
to synthesize non-latin1 characters. This however remains limited
to 16bit unicode like the rest of speakup. Any odd input or input
beyond 16bit is just discarded.

When userland echoes 8bit characters to /dev/synth with e.g.
echo -e '\xe9' > /dev/synth
synth_write would get characters beyond 0x7f, and thus negative when
char is signed. When given to synth_buffer_add which takes a u16, this
would sign-extend and produce a U+ffxy character rather than U+xy.
Users thus get garbled text instead of accents in their output.
Let's fix this by making sure that we read unsigned characters.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Jerrin will be the new maintainer of the VMware balloon driver following
Broadcom's acquisition and Nadav's departure.
Update accordingly:
1. Update the maintainer name and email.
2. Update the reviewer list to Broadcom's, which acquired VMware.
3. Add .mailmap entries for Nadav.

Currently, there are two entries for CONFIG_GOLDFISH.
In arch/x86/Kconfig:
config GOLDFISH
def_bool y
depends on X86_GOLDFISH
In drivers/platform/goldfish/Kconfig:
menuconfig GOLDFISH
bool "Platform support for Goldfish virtual devices"
depends on HAS_IOMEM && HAS_DMA
While Kconfig allows multiple entries, it generally leads to tricky
code.
Prior to commit bd2f348db503 ("goldfish: refactor goldfish platform
configs"), CONFIG_GOLDFISH was an alias of CONFIG_X86_GOLDFISH.
After the mentioned commit added the second entry with a user prompt,
the former provides the 'default' property that is effective only when
X86_GOLDFISH=y.
Merge them tegether to clarify how it has worked in the past 8 years.

The C standard specifies that there is no need to cast from a pointer to
void [1]. Therefore, it can be safely dropped.
