git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt:
- A revert for the mmap() change that ties the allocation range to the
hint adress, as what we tried to do ended up regressing on other
userspace workloads.
- A fix to avoid a kernel memory leak when emulating misaligned
accesses from userspace.
- A Kconfig fix for toolchain vector detection, which now correctly
detects vector support on toolchains where the V extension depends on
the M extension.
- A fix to avoid failing the linear mapping bootmem bounds check on
NOMMU systems.
- A fix for early alternatives on relocatable kernels.

Pull x86 kvm fixes from Paolo Bonzini:
"Many small fixes that accumulated while I was on vacation...
- Fixup missed comments from the REMOVED_SPTE => FROZEN_SPTE rename
- Ensure a root is successfully loaded when pre-faulting SPTEs
- Grab kvm->srcu when handling KVM_SET_VCPU_EVENTS to guard against
accessing memslots if toggling SMM happens to force a VM-Exit
- Emulate MSR_{FS,GS}_BASE on SVM even though interception is always
disabled, so that KVM does the right thing if KVM's emulator
encounters {RD,WR}MSR
- Explicitly clear BUS_LOCK_DETECT from KVM's caps on AMD, as KVM
doesn't yet virtualize BUS_LOCK_DETECT on AMD
- Cleanup the help message for CONFIG_KVM_AMD_SEV, and call out that
KVM now supports SEV-SNP too
- Specialize return value of
KVM_CHECK_EXTENSION(KVM_CAP_READONLY_MEM), based on VM type
- Remove unnecessary dependency on CONFIG_HIGH_RES_TIMERS
- Note an RCU quiescent state on guest exit. This avoids a call to
rcu_core() if there was a grace period request while guest was
running"

get_stashed_dentry() tries to optimistically retrieve a stashed dentry
from a provided location. It needs to ensure to hold rcu lock before it
dereference the stashed location to prevent UAF issues. Use
rcu_dereference() instead of READ_ONCE() it's effectively equivalent
with some lockdep bells and whistles and it communicates clearly that
this expects rcu protection.

Flow for creating Tx topology is the same as for VF port representors,
but the devlink port is stored in different place (sf->devlink_port).
When creating VF devlink lock isn't taken, when creating subfunction it
is. Setting Tx topology function needs to take this lock, check if it
was taken before to not do it twice.

Implement devlink port handlers responsible for ethernet type devlink
subfunctions. Create subfunction devlink port and setup all resources
needed for a subfunction netdev to operate. Configure new VSI for each
new subfunction, initialize and configure interrupts and Tx/Rx resources.
Set correct MAC filters and create new netdev.
For now, subfunction is limited to only one Tx/Rx queue pair.
Only allocate new subfunction VSI with devlink port new command.
Allocate and free subfunction MSIX interrupt vectors using new API
calls with pci_msix_alloc_irq_at and pci_msix_free_irq.
Support both automatic and manual subfunction numbers. If no subfunction
number is provided, use xa_alloc to pick a number automatically. This
will find the first free index and use that as the number. This reduces
burden on users in the simple case where a specific number is not
required. It may also be slightly faster to check that a number exists
since xarray lookup should be faster than a linear scan of the dyn_ports
xarray.

Now reshape supports two ways: with backup file or without backup file.
For the situation without backup file, it needs to change data offset.
It doesn't need systemd service mdadm-grow-continue. So it can finish
the reshape job in one process environment. It can know the new level
from mdadm --grow command and can change to new level after reshape
finishes.
For the situation with backup file, it needs systemd service
mdadm-grow-continue to monitor reshape progress. So there are two process
envolved. One is mdadm --grow command whick kicks off reshape and wakes
up mdadm-grow-continue service. The second process is the service, which
doesn't know the new level from the first process.
In kernel space mddev->new_level is used to record the new level when
doing reshape. This patch adds a new interface to help mdadm update
new_level and sync it to metadata. Then mdadm-grow-continue can read the
right new_level.

The zram_table_entry::flags member is of type long and uses 8 bytes on a
64bit architecture. With a PAGE_SIZE of 256KiB we have PAGE_SHIFT of 18
which in turn leads to __NR_ZRAM_PAGEFLAGS = 27. This still fits in an
ordinary integer.
By reducing the size of `flags' to four bytes, the size of the struct
goes back to 16 bytes. The padding between the lock and ac_time (if
enabled) is also gone.
Make zram_table_entry::flags an unsigned int and update the build test
to reflect the change.

The bit spinlock disables preemption. The spinlock_t lock becomes a sleeping
lock on PREEMPT_RT and it can not be acquired in this context. In this locked
section, zs_free() acquires a zs_pool::lock, and there is access to
zram::wb_limit_lock.
Add a spinlock_t for locking. Keep the set/ clear ZRAM_LOCK bit after
the lock has been acquired/ dropped. The size of struct zram_table_entry
increases by 4 bytes due to lock and additional 4 bytes padding with
CONFIG_ZRAM_TRACK_ENTRY_ACTIME enabled.

The version of the NBD protocol implemented by the kernel driver
currently has a 32 bit field for length values. As the NBD protocol uses
bytes as a unit of length, length values larger than 2^32 bytes cannot
be expressed.
Update the max_hw_discard_sectors field to match that.

BFQ has been lacking active maintenance for approximately two years, and it
was recently transitioned to the Orphan state. However, there are still
many users, I have decided to step forward and assume the role of
maintainer to ensure continued support and development.
While I may not be the one with the most extensive knowledge of BFQ's
internals, I have been actively involved in its development since 2021.
Moreover, our team continues to rigorously test BFQ in downstream kernels,
ensuring it's stability and performance. Despite my confidence to maintain
BFQ, I believe it is prudent to classify its state as "Odd Fixes" to
accurately reflect my relatively new position as the maintainer.
By assuming this responsibility, I am committed to providing the necessary
support and addressing any issues that may arise with BFQ. As time
progresses, we will reassess the situation and determine the appropriate
state.

Replace comma between expressions with semicolons.
Using a ',' in place of a ';' can have unintended side effects.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `struct_group_tagged()`
helper to create a new tagged `struct mt76_connac2_mcu_rxd_hdr`.
This structure groups together all the members of the flexible
`struct mt76_connac2_mcu_rxd` except the flexible array.
As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct mt76_connac2_mcu_rxd` to `struct
mt76_connac2_mcu_rxd_hdr`.
We also want to ensure that when new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.
This approach avoids having to implement `struct mt76_connac2_mcu_rxd_hdr`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
So, with these changes, fix the following warnings:
drivers/net/wireless/mediatek/mt76/mt7915/mcu.h:32:37: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
