fsl_mc_allocator_driver_exit() was added explicitly by
commit 1e8ac83b6caf ("bus: fsl-mc: add fsl_mc_allocator cleanup function")
but was never used.
Remove it.
fsl_mc_portal_reset() was added in 2015 by
commit 197f4d6a4a00 ("staging: fsl-mc: fsl-mc object allocator driver")
but was never used.
Remove it.
fsl_mc_portal_reset() was the only caller of dpmcp_reset().
Remove it.

This reverts commit 3dd075fe8ebbc6fcbf998f81a75b8c4b159a6195.
Tomasz has reported that his device, Generalplus Technology Inc. 808 Camera,
with ID 1b3f:2002, stopped being detected:
$ ls -l /dev/video*
zsh: no matches found: /dev/video*
[ 7.230599] usb 3-2: Found multiple Units with ID 5
This particular device is non-compliant, having both the Output Terminal
and Processing Unit with ID 5. uvc_scan_fallback, though, is able to build
a chain. However, when media elements are added and uvc_mc_create_links
call uvc_entity_by_id, it will get the incorrect entity,
media_create_pad_link will WARN, and it will fail to register the entities.
In order to reinstate support for such devices in a timely fashion,
reverting the fix for these warnings is appropriate. A proper fix that
considers the existence of such non-compliant devices will be submitted in
a later development cycle.

When block drivers or the core block code perform allocations with a
frozen queue, this could try to recurse into the block device to
reclaim memory and deadlock. Thus all allocations done by a process
that froze a queue need to be done without __GFP_IO and __GFP_FS.
Instead of tying to track all of them down, force a noio scope as
part of freezing the queue.
Note that nvme is a bit of a mess here due to the non-owner freezes,
and they will be addressed separately.

"Including fixes from IPSec, netfilter and Bluetooth.
Nothing really stands out, but as usual there's a slight concentration

wider distribution.
Current release - regressions:
- net: revert RTNL changes in unregister_netdevice_many_notify()
- Bluetooth: fix possible infinite recursion of btusb_reset
- eth: adjust locking in some old drivers which protect their state
with spinlocks to avoid sleeping in atomic; core protects netdev
state with a mutex now
Previous releases - regressions:
- eth:
- mlx5e: make sure we pass node ID, not CPU ID to kvzalloc_node()
- bgmac: reduce max frame size to support just 1500 bytes; the
jumbo frame support would previously cause OOB writes, but now
fails outright
- mptcp: blackhole only if 1st SYN retrans w/o MPC is accepted, avoid
false detection of MPTCP blackholing
Previous releases - always broken:
- mptcp: handle fastopen disconnect correctly
- xfrm:
- make sure skb->sk is a full sock before accessing its fields

Pull more s390 updates from Alexander Gordeev:
- The rework that uncoupled physical and virtual address spaces
inadvertently prevented KASAN shadow mappings from using large pages.
Restore large page mappings for KASAN shadows
- Add decompressor routine physmem_alloc() that may fail, unlike
physmem_alloc_or_die(). This allows callers to implement fallback
paths
- Allow falling back from large pages to smaller pages (1MB or 4KB) if
the allocation of 2GB pages in the decompressor can not be fulfilled
- Add to the decompressor boot print support of "%%" format string,
width and padding hadnling, length modifiers and decimal conversion
specifiers
- Add to the decompressor message severity levels similar to kernel
ones. Support command-line options that control console output
verbosity
- Replaces boot_printk() calls with appropriate loglevel- specific
helpers such as boot_emerg(), boot_warn(), and boot_debug().
- Collect all boot messages into a ring buffer independent of the
current log level. This is particularly useful for early crash
analysis
- If 'earlyprintk' command line parameter is not specified, store
decompressor boot messages in a ring buffer to be printed later by
the kernel, once the console driver is registered
- Add 'bootdebug' command line parameter to enable printing of
decompressor debug messages when needed. That parameters allows
message suppressing and filtering
- Dump boot messages on a decompressor crash, but only if 'bootdebug'
command line parameter is enabled
- When CONFIG_PRINTK_TIME is enabled, add timestamps to boot messages
in the same format as regular printk()
- Dump physical memory tracking information on boot: online ranges,
reserved areas and vmem allocations
- Dump virtual memory layout and randomization details
- Improve decompression error reporting and dump the message ring
buffer in case the boot failed and system halted
- Add an exception handler which handles exceptions when FPU control
register is attempted to be set to an invalid value. Remove '.fixup'
section as result of this change
- Use 'A', 'O', and 'R' inline assembly format flags, which allows
recent Clang compilers to generate better FPU code
- Rework uaccess code so it reads better and generates more efficient
code
- Cleanup futex inline assembly code
- Disable KMSAN instrumention for futex inline assemblies, which
contain dereferenced user pointers. Otherwise, shadows for the user
pointers would be accessed
- PFs which are not initially configured but in standby create only a
single-function PCI domain. If they are configured later on, sibling
PFs and their child VFs will not be added to their PCI domain
breaking SR-IOV expectations.
Fix that by allowing initially configured but in standby PFs create
multi-function PCI domains
- Add '-std=gnu11' to decompressor and purgatory CFLAGS to avoid
compile errors caused by kernel's own definitions of 'bool', 'false',
and 'true' conflicting with the C23 reserved keywords
- Fix sclp subsystem failure when a sclp console is not present
- Fix misuse of non-NULL terminated strings in vmlogrdr driver

bgmac allocates new replacement buffer before handling each received
frame. Allocating & DMA-preparing 9724 B each time consumes a lot of CPU
time. Ideally bgmac should just respect currently set MTU but it isn't
the case right now. For now just revert back to the old limited frame
size.
This change bumps NAT masquerade speed by ~95%.
Since commit 8218f62c9c9b ("mm: page_frag: use initial zero offset for
page_frag_alloc_align()"), the bgmac driver fails to open its network
interface successfully and runs out of memory in the following call
stack:
bgmac_open
-> bgmac_dma_init
-> bgmac_dma_rx_skb_for_slot
-> netdev_alloc_frag
BGMAC_RX_ALLOC_SIZE = 10048 and PAGE_FRAG_CACHE_MAX_SIZE = 32768.
Eventually we land into __page_frag_alloc_align() with the following
parameters across multiple successive calls:
__page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=0
__page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=10048
__page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=20096
__page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=30144
So in that case we do indeed have offset + fragsz (40192) > size (32768)
and so we would eventually return NULL. Reverting to the older 1500
bytes MTU allows the network driver to be usable again.

This fixes a regression caused by previous commit for fixing truncated
ACL data, which is causing some intermittent glitches when running two
A2DP streams.
serdev_device_write_buf() is the root cause of the glitch, which is
reverted, and the TX work will continue to write until the queue is empty.
This change fixes both issues. No A2DP streaming glitches or truncated
ACL data issue observed.

The documentation for usb_driver_claim_interface() says that "the
device lock" is needed when the function is called from places other
than probe(). This appears to be the lock for the USB interface
device. The Mediatek btusb code gets called via this path:
Workqueue: hci0 hci_power_on [bluetooth]
Call trace:
usb_driver_claim_interface
btusb_mtk_claim_iso_intf
btusb_mtk_setup
hci_dev_open_sync
hci_power_on
process_scheduled_works
worker_thread
kthread
With the above call trace the device lock hasn't been claimed. Claim
it.
Without this fix, we'd sometimes see the error "Failed to claim iso
interface". Sometimes we'd even see worse errors, like a NULL pointer
dereference (where `intf->dev.driver` was NULL) with a trace like:
Call trace:
usb_suspend_both
usb_runtime_suspend
__rpm_callback
rpm_suspend
pm_runtime_work
process_scheduled_works
Both errors appear to be fixed with the proper locking.

Commit 6e176bf8d461 ("PM: sleep: core: Do not skip callbacks in the
resume phase") overlooked the case in which the parent of a device with
DPM_FLAG_SMART_SUSPEND set did not use that flag and could be runtime-
suspended before a transition into a system-wide sleep state. In that
case, if the child is resumed during the subsequent transition from
that state into the working state, its runtime PM status will be set to
RPM_ACTIVE, but the runtime PM status of the parent will not be updated
accordingly, even though the parent will be resumed too, because of the
dev_pm_skip_suspend() check in device_resume_noirq().
Address this problem by tracking the need to set the runtime PM status
to RPM_ACTIVE during system-wide resume transitions for devices with
DPM_FLAG_SMART_SUSPEND set and all of the devices depended on by them.

bits so it is necessary to do some calculation when changing BSM to keep
the rest of the configuration as-is. However, when BSM is disabled, there
is no configuration with BLD enabled so this will be lost when coming back
to a mode with BSM enabled.

does not require the queue. As a result, the process_context_addr was
not assigned when the KFD process was released, ultimately leading to
this page fault during the execution of the function
kfd_process_dequeue_from_all_devices().
