Pull KVM fixes from Paolo Bonzini:
 "Many patches, pretty much all of them small, that accumulated while I
  was on vacation.

  ARM:

   - Remove the last leftovers of the ill-fated FPSIMD host state
     mapping at EL2 stage-1

   - Fix unexpected advertisement to the guest of unimplemented S2 base
     granule sizes

   - Gracefully fail initialising pKVM if the interrupt controller isn't
     GICv3

   - Also gracefully fail initialising pKVM if the carveout allocation
     fails

   - Fix the computing of the minimum MMIO range required for the host
     on stage-2 fault

   - Fix the generation of the GICv3 Maintenance Interrupt in nested
     mode

  x86:

   - Reject SEV{-ES} intra-host migration if one or more vCPUs are
     actively being created, so as not to create a non-SEV{-ES} vCPU in
     an SEV{-ES} VM

   - Use a pre-allocated, per-vCPU buffer for handling de-sparsification
     of vCPU masks in Hyper-V hypercalls; fixes a "stack frame too
     large" issue

   - Allow out-of-range/invalid Xen event channel ports when configuring
     IRQ routing, to avoid dictating a specific ioctl() ordering to
     userspace

   - Conditionally reschedule when setting memory attributes to avoid
     soft lockups when userspace converts huge swaths of memory to/from
     private

   - Add back MWAIT as a required feature for the MONITOR/MWAIT selftest

   - Add a missing field in struct sev_data_snp_launch_start that
     resulted in the guest-visible workarounds field being filled at the
     wrong offset

   - Skip non-canonical address when processing Hyper-V PV TLB flushes
     to avoid VM-Fail on INVVPID

   - Advertise supported TDX TDVMCALLs to userspace

   - Pass SetupEventNotifyInterrupt arguments to userspace

   - Fix TSC frequency underflow"

Pull CPU speculation fixes from Borislav Petkov:
 "Add the mitigation logic for Transient Scheduler Attacks (TSA)

  TSA are new aspeculative side channel attacks related to the execution
  timing of instructions under specific microarchitectural conditions.
  In some cases, an attacker may be able to use this timing information
  to infer data from other contexts, resulting in information leakage.

  Add the usual controls of the mitigation and integrate it into the
  existing speculation bugs infrastructure in the kernel"

af852f1f1c netlink: specs: enforce strict naming of properties
Add a regexp to make sure all names which may end up being visible
to the user consist of lower case characters, numbers and dashes.
Underscores keep sneaking into the specs, which is not visible
in the C code but makes the Python and alike inconsistent.

Note that starting with a number is okay, as in C the full
name will include the family name.

For legacy families we can't enforce the naming in the family
name or the multicast group names, as these are part of the
binary uAPI of the kernel.

For classic netlink we need to allow capital letters in names
of struct members. TC has some structs with capitalized members.

0981213407 dt-bindings: serial: 8250: Make clocks and clock-frequency exclusive
The 8250 binding before converting to json-schema states,

  - clock-frequency : the input clock frequency for the UART
  	or
  - clocks phandle to refer to the clk used as per Documentation/devicetree

for clock-related properties, where "or" indicates these properties
shouldn't exist at the same time.

Additionally, the behavior of Linux's driver is strange when both clocks
and clock-frequency are specified: it ignores clocks and obtains the
frequency from clock-frequency, left the specified clocks unclaimed. It
may even be disabled, which is undesired most of the time.

But "anyOf" doesn't prevent these two properties from coexisting, as it
considers the object valid as long as there's at LEAST one match.

Let's switch to "oneOf" and disallows the other property if one exists,
precisely matching the original binding and avoiding future confusion on
the driver's behavior.

7484e15dbb replace collect_mounts()/drop_collected_mounts() with a safer variant
collect_mounts() has several problems - one can't iterate over the results
directly, so it has to be done with callback passed to iterate_mounts();
it has an oopsable race with d_invalidate(); it creates temporary clones
of mounts invisibly for sync umount (IOW, you can have non-lazy umount
succeed leaving filesystem not mounted anywhere and yet still busy).

A saner approach is to give caller an array of struct path that would pin
every mount in a subtree, without cloning any mounts.

        * collect_mounts()/drop_collected_mounts()/iterate_mounts() is gone
        * collect_paths(where, preallocated, size) gives either ERR_PTR(-E...) or
a pointer to array of struct path, one for each chunk of tree visible under
'where' (i.e. the first element is a copy of where, followed by (mount,root)
for everything mounted under it - the same set collect_mounts() would give).
Unlike collect_mounts(), the mounts are *not* cloned - we just get pinning
references to the roots of subtrees in the caller's namespace.
        Array is terminated by {NULL, NULL} struct path.  If it fits into
preallocated array (on-stack, normally), that's where it goes; otherwise
it's allocated by kmalloc_array().  Passing 0 as size means that 'preallocated'
is ignored (and expected to be NULL).
        * drop_collected_paths(paths, preallocated) is given the array returned
by an earlier call of collect_paths() and the preallocated array passed to that
call.  All mount/dentry references are dropped and array is kfree'd if it's not
equal to 'preallocated'.
        * instead of iterate_mounts(), users should just iterate over array
of struct path - nothing exotic is needed for that.  Existing users (all in
audit_tree.c) are converted.

25e8b1dd48 KVM: TDX: Exit to userspace for GetTdVmCallInfo
Exit to userspace for TDG.VP.VMCALL<GetTdVmCallInfo> via KVM_EXIT_TDX,
to allow userspace to provide information about the support of
TDVMCALLs when r12 is 1 for the TDVMCALLs beyond the GHCI base API.

GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>,
<ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>,
<Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and
<Instruction.WRMSR>. They must be supported by VMM to support TDX guests.

For GetTdVmCallInfo
- When leaf (r12) to enumerate TDVMCALL functionality is set to 0,
  successful execution indicates all GHCI base TDVMCALLs listed above are
  supported.

  Update the KVM TDX document with the set of the GHCI base APIs.

- When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it
  indicates the TDX guest is querying the supported TDVMCALLs beyond
  the GHCI base TDVMCALLs.
  Exit to userspace to let userspace set the TDVMCALL sub-function bit(s)
  accordingly to the leaf outputs.  KVM could set the TDVMCALL bit(s)
  supported by itself when the TDVMCALLs don't need support from userspace
  after returning from userspace and before entering guest. Currently, no
  such TDVMCALLs implemented, KVM just sets the values returned from

cf207eac06 KVM: TDX: Handle TDG.VP.VMCALL<GetQuote>
Handle TDVMCALL for GetQuote to generate a TD-Quote.

GetQuote is a doorbell-like interface used by TDX guests to request VMM
to generate a TD-Quote signed by a service hosting TD-Quoting Enclave
operating on the host.  A TDX guest passes a TD Report (TDREPORT_STRUCT) in
a shared-memory area as parameter.  Host VMM can access it and queue the
operation for a service hosting TD-Quoting enclave.  When completed, the
Quote is returned via the same shared-memory area.

KVM only checks the GPA from the TDX guest has the shared-bit set and drops
the shared-bit before exiting to userspace to avoid bleeding the shared-bit
into KVM's exit ABI.  KVM forwards the request to userspace VMM (e.g. QEMU)
and userspace VMM queues the operation asynchronously.  KVM sets the return
code according to the 'ret' field set by userspace to notify the TDX guest
whether the request has been queued successfully or not.  When the request
has been queued successfully, the TDX guest can poll the status field in
the shared-memory area to check whether the Quote generation is completed
or not.  When completed, the generated Quote is returned via the same
buffer.

Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is
required to handle the KVM exit reason as the initial support for TDX,

  The ath12k fix to avoid FW crashes requires adding support for a

   - ptp: fix breakage after ptp_vclock_in_use() rework

   - openvswitch: allocate struct ovs_pcpu_storage dynamically, static

d4adf1c9ee bpf: Adjust free target to avoid global starvation of LRU map
BPF_MAP_TYPE_LRU_HASH can recycle most recent elements well before the
map is full, due to percpu reservations and force shrink before
neighbor stealing. Once a CPU is unable to borrow from the global map,
it will once steal one elem from a neighbor and after that each time
flush this one element to the global list and immediately recycle it.

Batch value LOCAL_FREE_TARGET (128) will exhaust a 10K element map
with 79 CPUs. CPU 79 will observe this behavior even while its
neighbors hold 78 * 127 + 1 * 15 == 9921 free elements (99%).

CPUs need not be active concurrently. The issue can appear with
affinity migration, e.g., irqbalance. Each CPU can reserve and then
hold onto its 128 elements indefinitely.

Avoid global list exhaustion by limiting aggregate percpu caches to
half of map size, by adjusting LOCAL_FREE_TARGET based on cpu count.
This change has no effect on sufficiently large tables.

Similar to LOCAL_NR_SCANS and lru->nr_scans, introduce a map variable
lru->free_target. The extra field fits in a hole in struct bpf_lru.
The cacheline is already warm where read in the hot path. The field is
only accessed with the lru lock held.
