With EIOINTC interrupt controller, physical CPU ID is set for irq route.
However the function kvm_get_vcpu() is used to get destination vCPU when
delivering irq. With API kvm_get_vcpu(), the logical CPU ID is used.
With API kvm_get_vcpu_by_cpuid(), vCPU ID can be searched from physical
CPU ID.

With function eiointc_update_sw_coremap(), there is forced assignment
like val = *(u64 *)pvalue. Parameter pvalue may be pointer to char type
or others, there is problem with forced assignment with u64 type.
Here the detailed value is passed rather address pointer.

IOCSR instruction supports 1/2/4/8 bytes access, the address should be
naturally aligned with its access size. Here address alignment check is
added in the EIOINTC kernel emulation.

Pull bcachefs fixes from Kent Overstreet:
- Lots of small check/repair fixes, primarily in subvol loop and
directory structure loop (when involving snapshots).
- Fix a few 6.16 regressions: rare UAF in the foreground allocator path
when taking a transaction restart from the transaction bump
allocator, and some small fallout from the change to log the error
being corrected in the journal when repairing errors, also some
fallout from the btree node read error logging improvements.
(Alan, Bharadwaj)
- New option: journal_rewind
This lets the entire filesystem be reset to an earlier point in time.
Note that this is only a disaster recovery tool, and right now there
are major caveats to using it (discards should be disabled, in
particular), but it successfully restored the filesystem of one of
the users who was bit by the subvolume deletion bug and didn't have
backups. I'll likely be making some changes to the discard path in
the future to make this a reliable recovery tool.
- Some new btree iterator tracepoints, for tracking down some
livelock-ish behaviour we've been seeing in the main data write path.

A previous commit aborted mapping more for a non-incremental ring for
bundle peeking, but depending on where in the process this peeking
happened, it would not necessarily prevent a retry by the user. That can
create gaps in the received/read data.
Add struct buf_sel_arg->partial_map, which can pass this information
back. The networking side can then map that to internal state and use it
to gate retry as well.
Since this necessitates a new flag, change io_sr_msg->retry to a
retry_flags member, and store both the retry and partial map condition
in there.

When performing a file read from RDMA, smbd_recv() prints an "Invalid msg
type 4" error and fails the I/O. This is due to the switch-statement there
not handling the ITER_FOLIOQ handed down from netfslib.
Fix this by collapsing smbd_recv_buf() and smbd_recv_page() into
smbd_recv() and just using copy_to_iter() instead of memcpy(). This
future-proofs the function too, in case more ITER_* types are added.

The handling of received data in the smbdirect client code involves using
copy_to_iter() to copy data from the smbd_reponse struct's packet trailer
to a folioq buffer provided by netfslib that encapsulates a chunk of
pagecache.
If, however, CONFIG_HARDENED_USERCOPY=y, this will result in the checks
then performed in copy_to_iter() oopsing with something like the following:
CIFS: Attempting to mount //172.31.9.1/test
CIFS: VFS: RDMA transport established
usercopy: Kernel memory exposure attempt detected from SLUB object 'smbd_response_0000000091e24ea1' (offset 81, size 63)!

The problem is that the smbd_response slab's packet field isn't marked as

Fix this by passing parameters to kmem_slab_create() to indicate that
copy_to_iter() is permitted from the packet region of the smbd_response

While bdev_count_inflight is interating all cpus, if some IOs are issued

// cpu0 is 0
infliht += 0

// cpu 1 is 0
inflight += 0

...
In this case, the total inflight will be -1, causing lots of false

While we are indirectly draining our dedicated workqueue ggtt->wq
that we use to complete asynchronous removal of some GGTT nodes,
this happends as part of the managed-drm unwinding (ggtt_fini_early),
which could be later then manage-device unwinding, where we could
already unmap our MMIO/GMS mapping (mmio_fini).

During driver probe we might be briefly using CT safe mode, which
is based on a delayed work, but usually we are able to stop this
once we have IRQ fully operational. However, if we abort the probe
quite early then during unwind we might try to destroy the workqueue
while there is still a pending delayed work that attempts to restart
itself which triggers a WARN.
This was recently observed during unsuccessful VF initialization:
[ ] xe 0000:00:02.1: probe with driver xe failed with error -62
[ ] ------------[ cut here ]------------

When the KCOV is enabled all functions get instrumented, unless
the __no_sanitize_coverage attribute is used. To prepare for
__no_sanitize_coverage being applied to __init functions, we have to

For LoongArch this exposed several places where __init annotations
were missing but ended up being "accidentally correct". So fix these

The EFI memory map at 'boot_memmap' is crucial for kdump to understand
the primary kernel's memory layout. This memory region, typically part
of EFI Boot Services (BS) data, can be overwritten after ExitBootServices
if not explicitly preserved by the kernel.
This commit addresses this by:
1. Calling memblock_reserve() to reserve the entire physical region
occupied by the EFI memory map (header + descriptors). This prevents
the primary kernel from reallocating and corrupting this area.
2. Setting the EFI_PRESERVE_BS_REGIONS flag in efi.flags. This indicates
that efforts have been made to preserve critical BS code/data regions
which can be useful for other kernel subsystems or debugging.
These changes ensure the original EFI memory map data remains intact,
improving kdump reliability and potentially aiding other EFI-related
functionalities that might rely on preserved BS code/data.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembler code, __ASSEMBLY__ is a macro
that only gets defined by the Makefiles in the kernel. This is bad
since macros starting with two underscores are names that are reserved
by the C language. It can also be very confusing for the developers
when switching between userspace and kernelspace coding, or when
dealing with uapi headers that rather should use __ASSEMBLER__ instead.
So let's now standardize on the __ASSEMBLER__ macro that is provided
by the compilers.
This is almost a completely mechanical patch (done with a simple
"sed -i" statement), with one comment tweaked manually in the
arch/loongarch/include/asm/cpu.h file (it was missing the trailing
underscores).

The remove_work will proceed with permanently disconnecting on the
initial final path failure if the head shows no paths after the delay.
If a new path connects while the remove_work is pending, and if that new
path happens to disconnect before that remove_work executes, the delayed
removal should reset based on the most recent path disconnect time, but
queue_delayed_work() won't do anything if the work is already pending.
Attempt to cancel the delayed work when a new path connects, and use
mod_delayed_work() in case the remove_work remains pending anyway.

If an AUX event overruns, the event core layer intends to disable the
event by setting the 'pending_disable' flag. Unfortunately, the event
is not actually disabled afterwards.
In commit:
ca6c21327c6a ("perf: Fix missing SIGTRAPs")
the 'pending_disable' flag was changed to a boolean. However, the
AUX event code was not updated accordingly. The flag ends up holding a
CPU number. If this number is zero, the flag is taken as false and the
IRQ work is never triggered.
Later, with commit:
2b84def990d3 ("perf: Split __perf_pending_irq() out of perf_pending_irq()")
a new IRQ work 'pending_disable_irq' was introduced to handle event
disabling. The AUX event path was not updated to kick off the work queue.
To fix this bug, when an AUX ring buffer overrun is detected, call
perf_event_disable_inatomic() to initiate the pending disable flow.
Also update the outdated comment for setting the flag, to reflect the
boolean values (0 or 1).

Fix a 6.16 regression from the recovery pass rework, which introduced a
bug where calling bch2_run_explicit_recovery_pass() would only return
the error code to rewind recovery for the first call that scheduled that
recovery pass.
If the error code from the first call was swallowed (because it was
called by an asynchronous codepath), subsequent calls would go "ok, this
pass is already marked as needing to run" and return 0.
Fixing this ensures that check_topology bails out to run btree_node_scan

Previously, calling bch2_btree_has_scanned_nodes() when btree node

This fixes a 6.16 regression from moving the scheduling of btree node

it persistently in the superblock) and only scheduling it when
check_toploogy() is asking for scanned btree nodes.

syzbot reported a warning below during atm_dev_register(). [0]
Before creating a new device and procfs/sysfs for it, atm_dev_register()
looks up a duplicated device by __atm_dev_lookup(). These operations are
done under atm_dev_mutex.
However, when removing a device in atm_dev_deregister(), it releases the
mutex just after removing the device from the list that __atm_dev_lookup()
iterates over.
So, there will be a small race window where the device does not exist on
the device list but procfs/sysfs are still not removed, triggering the
splat.
Let's hold the mutex until procfs/sysfs are removed in
atm_dev_deregister().

validate_addr() checks whether the address returned by mmap() lies in the
low or high VA space, according to whether a high addr hint was passed or
not. The fix commit mentioned below changed the code in such a way that
this function will always return failure when passed high_addr == 1; addr
will be >= HIGH_ADDR_MARK always, we will fall down to "if (addr >
HIGH_ADDR_MARK)" and return failure. Fix this.

The dm_crypt code fails to build without CONFIG_KEYS:
kernel/crash_dump_dm_crypt.c: In function 'restore_dm_crypt_keys_to_thread_keyring':
kernel/crash_dump_dm_crypt.c:105:9: error: unknown type name 'key_ref_t'; did you mean 'key_ref_put'?
There is a mix of 'select KEYS' and 'depends on KEYS' in Kconfig,
so there is no single obvious solution here, but generally using 'depends on'
makes more sense and is less likely to cause dependency loops.

The WARN_ON_ONCE is introduced on truncate_folio_batch_exceptionals() to
capture whether the filesystem has removed all DAX entries or not.
And the fix has been applied on the filesystem xfs and ext4 by the commit
0e2f80afcfa6 ("fs/dax: ensure all pages are idle prior to filesystem
unmount").
Apply the missed fix on filesystem fuse to fix the runtime warning:
