Reject LAUNCH_FINISH for SEV-ES and SNP VMs if KVM is actively creating
one or more vCPUs, as KVM needs to process and encrypt each vCPU's VMSA.
Letting userspace create vCPUs while LAUNCH_FINISH is in-progress is
"fine", at least in the current code base, as kvm_for_each_vcpu() operates
on online_vcpus, LAUNCH_FINISH (all SEV+ sub-ioctls) holds kvm->mutex, and
fully onlining a vCPU in kvm_vm_ioctl_create_vcpu() is done under
kvm->mutex. I.e. there's no difference between an in-progress vCPU and a
vCPU that is created entirely after LAUNCH_FINISH.
However, given that concurrent LAUNCH_FINISH and vCPU creation can't
possibly work (for any reasonable definition of "work"), since userspace
can't guarantee whether a particular vCPU will be encrypted or not,
disallow the combination as a hardening measure, to reduce the probability
of introducing bugs in the future, and to avoid having to reason about the
safety of future changes related to LAUNCH_FINISH.

The static stack liveness analysis needs to know how many bytes a
helper or kfunc accesses through a stack pointer argument, so it can
precisely mark the affected stack slots as stack 'def' or 'use'.
Add bpf_helper_stack_access_bytes() and bpf_kfunc_stack_access_bytes()
which resolve the access size for a given call argument.

Add two passes before the main verifier pass:
bpf_compute_const_regs() is a forward dataflow analysis that tracks
register values in R0-R9 across the program using fixed-point
iteration in reverse postorder. Each register is tracked with
a six-state lattice:
UNVISITED -> CONST(val) / MAP_PTR(map_index) /
MAP_VALUE(map_index, offset) / SUBPROG(num) -> UNKNOWN
At merge points, if two paths produce the same state and value for
a register, it stays; otherwise it becomes UNKNOWN.
The analysis handles:
- MOV, ADD, SUB, AND with immediate or register operands
- LD_IMM64 for plain constants, map FDs, map values, and subprogs
- LDX from read-only maps: constant-folds the load by reading the
map value directly via bpf_map_direct_read()
Results that fit in 32 bits are stored per-instruction in
insn_aux_data and bitmasks.
bpf_prune_dead_branches() uses the computed constants to evaluate
conditional branches. When both operands of a conditional jump are
known constants, the branch outcome is determined statically and the
instruction is rewritten to an unconditional jump.
The CFG postorder is then recomputed to reflect new control flow.
This eliminates dead edges so that subsequent liveness analysis
doesn't propagate through dead code.
Also add runtime sanity check to validate that precomputed
constants match the verifier's tracked state.

Add a pass that sorts subprogs in topological order so that iterating
subprog_topo_order[] walks leaf subprogs first, then their callers.
This is computed as a DFS post-order traversal of the CFG.
The pass runs after check_cfg() to ensure the CFG has been validated
before traversing and after postorder has been computed to avoid
walking dead code.

Export the Q7.8 volume control helpers to allow reuse
by other ASoC drivers. These functions handle 16-bit
signed Q7.8 fixed-point format values for volume controls.
Changes include:
- Rename q78_get_volsw to sdca_asoc_q78_get_volsw
- Rename q78_put_volsw to sdca_asoc_q78_put_volsw
- Add a convenience macro SDCA_SINGLE_Q78_TLV and
SDCA_DOUBLE_Q78_TLV for creating mixer controls
This allows other ASoC drivers to easily implement controls
using the Q7.8 fixed-point format without duplicating code.

svc_rqst_replace_page() releases displaced pages through a
per-rqst folio batch, but exposes the add-or-flush sequence
directly. svc_tcp_restore_pages() releases displaced pages
individually with put_page().
Introduce svc_rqst_page_release() to encapsulate the
batched release mechanism. Convert svc_rqst_replace_page()
and svc_tcp_restore_pages() to use it. The latter now
benefits from the same batched release that
svc_rqst_replace_page() already uses.

As we add functionality to proxy execution, we may migrate a
donor task to a runqueue where it can't run due to cpu affinity.
Thus, we must be careful to ensure we return-migrate the task
back to a cpu in its cpumask when it becomes unblocked.
Peter helpfully provided the following example with pictures:
"Suppose we have a ww_mutex cycle:
,-+-* Mutex-1 <-.
Task-A ---' | | ,-- Task-B
`-> Mutex-2 *-+-'
Where Task-A holds Mutex-1 and tries to acquire Mutex-2, and
where Task-B holds Mutex-2 and tries to acquire Mutex-1.
Then the blocked_on->owner chain will go in circles.
Task-A -> Mutex-2
^ |
| v
Mutex-1 <- Task-B
We need two things:
- find_proxy_task() to stop iterating the circle;
- the woken task to 'unblock' and run, such that it can
back-off and re-try the transaction.
Now, the current code [without this patch] does:
__clear_task_blocked_on();
wake_q_add();
And surely clearing ->blocked_on is sufficient to break the
cycle.
Suppose it is Task-B that is made to back-off, then we have:
Task-A -> Mutex-2 -> Task-B (no further blocked_on)
and it would attempt to run Task-B. Or worse, it could directly
pick Task-B and run it, without ever getting into
find_proxy_task().
Now, here is a problem because Task-B might not be runnable on
the CPU it is currently on; and because !task_is_blocked() we
don't get into the proxy paths, so nobody is going to fix this
up.
Ideally we would have dequeued Task-B alongside of clearing
->blocked_on, but alas, [the lock ordering prevents us from
getting the task_rq_lock() and] spoils things."
Thus we need more than just a binary concept of the task being
blocked on a mutex or not.
So allow setting blocked_on to PROXY_WAKING as a special value
which specifies the task is no longer blocked, but needs to
be evaluated for return migration *before* it can be run.
This will then be used in a later patch to handle proxy
return-migration.

So far, we have been able to utilize the mutex::wait_lock
for serializing the blocked_on state, but when we move to
proxying across runqueues, we will need to add more state
and a way to serialize changes to this state in contexts
where we don't hold the mutex::wait_lock.
So introduce the task::blocked_lock, which nests under the
mutex::wait_lock in the locking order, and rework the locking
to use it.

Currently the high-level xor code chunks up all operations into small
units for only up to 1 + 4 vectors, and passes it to four different
methods. This means the FPU/vector context is entered and left a lot for
wide stripes, and a lot of indirect expensive indirect calls are
performed. Switch to passing the entire gen_xor request to the low-level
ops, and provide a macro to dispatch it to the existing helper.
This reduce the number of indirect calls and FPU/vector context switches
by a factor approaching nr_stripes / 4, and also reduces source and binary
code size.

xor_blocks is very annoying to use, because it is limited to 4 + 1 sources
/ destinations, has an odd argument order and is completely undocumented.
Lift the code that loops around it from btrfs and async_tx/async_xor into
common code under the name xor_gen and properly document it.

Move the generic implementations from asm-generic/xor.h to
per-implementaion .c files in lib/raid. This will build them
unconditionally even when an architecture forces a specific
implementation, but as we'll need at least one generic version for the
static_call optimization later on we'll pay that price.
Note that this would cause the second xor_block_8regs instance created by
arch/arm/lib/xor-neon.c to be generated instead of discarded as dead code,
so add a NO_TEMPLATE symbol to disable it for this case.

Drop the pretty confusing historic XOR_TRY_TEMPLATES and
XOR_SELECT_TEMPLATE, and instead let the architectures provide a
arch_xor_init that calls either xor_register to register candidates or
xor_force to force a specific implementation.

In a subsequent patch, the regs_refine_cond_op and reg_bounds_sync
functions will be called in is_branch_taken instead of reg_set_min_max,
to simulate each branch's outcome. Since they will run before we branch
out, these two functions will need to work on temporary registers for
the two branches.
This refactoring patch prepares for that change, by introducing the
temporary registers on bpf_verifier_env and using them in
reg_set_min_max.
This change also allows us to save one fake_reg slot as we don't need to
allocate an additional temporary buffer in case of a BPF_K condition.
Finally, you may notice that this patch removes the check for
"false_reg1 == false_reg2" in reg_set_min_max. That check was introduced
in commit d43ad9da8052 ("bpf: Skip bounds adjustment for conditional
jumps on same scalar register") to avoid an invariant violation. Given
that "env->false_reg1 == env->false_reg2" doesn't make sense and
invariant violations are addressed in a subsequent commit, this patch
just removes the check.

Implement the standard ETHTOOL_PHY_DOWNSHIFT tunable for the LAN88xx
PHY. This allows runtime configuration of the auto-downshift feature
via ethtool:
ethtool --set-phy-tunable eth0 downshift on count 3
The LAN88xx PHY supports downshifting from 1000BASE-T to 100BASE-TX
after 2-5 failed auto-negotiation attempts. Valid count values are
2, 3, 4 and 5.
This is based on an earlier downstream implementation by Phil Elwell.

"stdrng" is needed only in "FIPS mode". Therefore, make
crypto_stdrng_get_bytes() delegate to either the normal Linux RNG or to
"stdrng", depending on the current mode.
This will eliminate the need to built the SP800-90A DRBG and its
dependencies into CRYPTO_FIPS=n kernels.

All callers of crypto_get_default_rng() use the following sequence:
crypto_get_default_rng()
crypto_rng_get_bytes(crypto_default_rng, ...)
crypto_put_default_rng()
While it may have been intended that callers amortize the cost of
getting and putting the "default RNG" (i.e. "stdrng") over multiple
calls, in practice that optimization is never used. The callers just
want a function that gets random bytes from the "stdrng".
Therefore, add such a function: crypto_stdrng_get_bytes().
Importantly, this decouples the callers from the crypto_rng API. That
allows a later commit to make this function simply call
get_random_bytes_wait() unless the kernel is in "FIPS mode".

firmware: tegra: Changes for v7.1-rc1
This introduces a new API for the BPMP to be pass along a specifier from
DT when getting a reference from a phandle. This is used to reference
specific instances of the PCI controller on Tegra264. The ABI header for
BPMP is updated to the latest version and BPMP APIs now use the more
intuitive ENODEV instead of the non SUSV4 ENOTSUPP error code for stub
implementations.

Reset controller fixes for v7.0, part 2
* Decouple spacemit K3 reset lines that were incorrectly coupled
together as one, but are in fact separate resets in hardware.
* Fix a double free in the reset_add_gpio_aux_device() error path.
This has already been fixed on reset/next by commit a9b95ce36de4
("reset: gpio: add a devlink between reset-gpio and its consumer").
* Fix the MODULE_AUTHOR string in the rzg2l-usbphy-ctrl driver.
We merge this into reset/next to resolve a conflict between commits
a9b95ce36de4 ("reset: gpio: add a devlink between reset-gpio and its
consumer") and fbffb8c7c7bb ("reset: gpio: fix double free in
reset_add_gpio_aux_device() error path").

cpufreq_cpu_get() can sleep on PREEMPT_RT in presence of concurrent
writer(s), however amd-pstate depends on fetching the cpudata via the
policy's driver data which necessitates grabbing the reference.
Since schedutil governor can call "cpufreq_driver->update_perf()"
during sched_tick/enqueue/dequeue with rq_lock held and IRQs disabled,
fetching the policy object using the cpufreq_cpu_get() helper in the
scheduler fast-path leads to "BUG: scheduling while atomic" on
PREEMPT_RT [1].
Pass the cached cpufreq policy object in sg_policy to the update_perf()
instead of just the CPU. The CPU can be inferred using "policy->cpu".
The lifetime of cpufreq_policy object outlasts that of the governor and
the cpufreq driver (allocated when the CPU is onlined and only reclaimed
when the CPU is offlined / the CPU device is removed) which makes it
safe to be referenced throughout the governor's lifetime.

Srinivas Kandagatla <srinivas.kandagatla@oss.qualcomm.com> says:
This patchset contains few fixes for the bugs hit during testing with
Monza EVK platform
- around array out of bounds access on dai ids which keep extending but
the drivers seems to have hardcoded some numbers, fix this and clean
the mess up
- fix few issues discovered while trying to shut down dsp.
- flooding rpmsg with write requests due to not resetting queue pointer,
fix this resetting the pointer in trigger stop.
- possible multiple graph opens which can result in open failures.
Apart from this few new enhancements to the dsp side
- add new LPI MI2S and senary dai entries
- handle pipewire and Displayport issues by moving graph start to
trigger level, which should fix outstanding pipewire and DP issues on
Qualcomm SoCs.
- remove some unnessary loops in hot path
- support early memory map on DSP.
Tested this on top of linux-next on VENTUNO-Q platform.

xHCI hardware maintains its endpoint state between add_endpoint()
and drop_endpoint() calls followed by successful check_bandwidth().
So does the driver.
Core may call endpoint_disable() during xHCI endpoint life, so don't
clear host_ep->hcpriv then, because this breaks endpoint_reset().
If a driver calls usb_set_interface(), submits URBs which make host
sequence state non-zero and calls usb_clear_halt(), the device clears
its sequence state but xhci_endpoint_reset() bails out. The next URB
malfunctions: USB2 loses one packet, USB3 gets Transaction Error or
may not complete at all on some (buggy?) HCs from ASMedia and AMD.
This is triggered by uvcvideo on bulk video devices.
The code was copied from ehci_endpoint_disable() but it isn't needed
here - hcpriv should only be NULL on emulated root hub endpoints.
It might prevent resetting and inadvertently enabling a disabled and
dropped endpoint, but core shouldn't try to reset dropped endpoints.
Document xhci requirements regarding hcpriv. They are currently met.

There is an existing comedi_request_region(dev, start, len) function
used by COMEDI drivers for legacy devices to request an I/O port region
starting at a specified base address (which must be non-zero) and with a
specified length. It uses request_region(). On success, it sets
dev->iobase and dev->iolen and returns 0. There is a alternative
function __comedi_request_region(dev, start, len) which does the same
thing without setting dev->iobase and dev->iolen.
Most hardware devices have restrictions on the allowed I/O port base
address and alignment, so add new functions
comedi_check_request_region(dev, start, len, minstart, maxend, minalign)
and __comedi_check_request_region(dev, start, len, minstart, maxend,
minalign) to perform these additional checks. Turn the original
functions into static inline wrapper functions that call the new
functions.

Rather than querying the output device for its address in
mctp_local_output, set up the source address when we're populating the
dst structure. If no address is assigned, use MCTP_ADDR_NULL.
This will allow us more flexibility when routing for NULL-source-eid
cases. For now though, we still reject a NULL source address in the
output path.
We need to update the tests a little, so that addresses are assigned
before we do the dst lookups.

Making ->d_rcu and (then) ->d_child overlapping dates back to
2006; anon unions support had been added to gcc only in 4.6
(2011) and the minimal gcc version hadn't been bumped to that
until 4.19 (2018).
These days there's no reason not to keep that union named.

Most of the places using d_alias are loops iterating through all aliases for
given inode; introduce a helper macro (for_each_alias(dentry, inode))
and convert open-coded instances of such loop to it.
They are easier to read that way and it reduces the noise on the next steps.
You _must_ hold inode->i_lock over that thing.

Replace the coarse USB device lock with a dedicated offload_lock
spinlock to reduce contention during offload operations. Use
offload_pm_locked to synchronize with PM transitions and replace
the legacy offload_at_suspend flag.
Optimize usb_offload_get/put by switching from auto-resume/suspend
to pm_runtime_get_if_active(). This ensures offload state is only
modified when the device is already active, avoiding unnecessary
power transitions.
